  5. 5. 5 Before we start ... I love Notes.
  6. 6. 6 Your IBM Notes Client: Version 9.0.1 FP2 > 20.000 41.000 files (Notes 6/7 | 8/9 Basic used to have ~550) = +7.400%  17.000 21.800 files in Notes Programframework in 1.800 2.150 subdirectories  7.500 8.800 (largely undocumented) .properties files  1.500 1.600 jar files  1.200 1.300 HTML files  3.000 1.182 files in Notes Dataworkspace in 2.400subdirectories, out of which 1,850 are empty 700 subdirectories  900 180 (largely undocumented) XML files  100+ 80 (largely undocumented) .properties files  Which is  20.000 41.000 files in 4.600 4.860 subdirectories  8.500+ 9.000+ largely undocumented files  Many (many many) subdirectories are plain empty, especially in Dataworkspace  ... and around 100 NSFs/NTFs (=0.5 0.2 %)  ... and the good old notes.ini file
  7. 7. 7 Your IBM Notes Client: Version 9.0.1 FP2 - Continued Add over 80 preference/dialog boxes • Each dialog has ~15 settings at average For a total of 1,200+ settings sprayed across • address book (very few) • notes.ini (few) • and XML files (lots) Plus any plugins, widgets, add-ons, etc. “you“ or the user may have added to the Notes client install
  8. 8. 8 Your IBM Notes Client: Version 9.0.1 FP2 - Continued Search Sidebar Shortcut Buttons Toolbars Bookmarkbar

  10. 10. 10 Agenda A Performance Boost for your IBM Notes Client Your IBM Notes Client: Version 9.0.1 What makes your Notes Client START slow What makes your Notes Client PERFORM slow Performance Tips and Tricks
  11. 11. 11 What makes your Notes Client START slow If you‘re not on at least 9.0.1 yet  9.0.1 is a significant improvement  Pre-loading the client might also be recommended EOM of IBM Lotus products  http://www-01.ibm.com/software/lotus/support/lifecycle/
  12. 12. 12 What makes your Notes Client START slow - Continued ~50% of the entire data volume in the Data directory changes on a DAILY basis in most setups  5 - 10% in Dataworkspace ( up to 300 files)  DISABLE Antivirus scanning for at least *.ns* in Data Directory. Period.
  13. 13. 13 What makes your Notes Client START slow - Continued Client crashes/database fixups  especially bad for network based data directories clients Outdated Hardware  You need >1-2 GB memory if you want to use Notes AND something else  Old fixed disks with fragmentation  Fun Exercise: Buy a small Solid State Disk and make Notes boot off of that ;-) Tons of startup programs/scripts launching during the “boot storm”  if the disk is unable to keep up, it‘s not Notes' fault  Again, see http://bit.ly/ACzO6Z
  14. 14. 14 What makes your Notes Client START slow - Continued Outdated Data directories  Virtually 100% of all NTFs (Laptops: 90%) can be removed by  Cleaning up old Notes 4+5+6 templates  using ini:SharedDataDirectory= (also with Single User install!) Operating System  Windows 7 boots ~40% faster than XP  Windows 8 ~55% faster than XP  ~20% faster than Windows 7, supposedly
  15. 15. 15 What makes your Notes Client START slow - ODS ODS = On Disk Structure  ODS 16 = Notes 2  ODS 17 = Notes 3  ODS 20 = Notes 4 (oder Templates)  ODS 41 = Notes 5  ODS 43 = Notes 6 & 7  ODS 48 = Notes 8  ODS 51 = Notes 8.5 & 9  ODS 52 = Notes 9.0.1 The difference between ODS 43 and 51 = up to 80% LESS FILE I/O This helps with ANY client AND server hardware
  16. 16. 16 What makes your Notes Client START slow – ODS - Continued CAUTION: The ODS is not automatically updated when upgrading clients  Except for names.nsf, bookmark.nsf, and desktop*.dsk/ndk – IF – you upgrade properly (think ini:Setup/TemplateSetup=)  ODS 48 requires Notes >= 8 and CREATE_R8_DATABASES=1 in notes.ini for NEW db's  ODS 52 requires Notes >= 9.0.1 and CREATE_R9_DATABASES=1 in notes.ini for NEW db's Good News for Notes > 8.5  Use NSF_UpdateODS=1 with CREATE_R85/9_DATABASES=1 for a one-time upgrade of most local databases  NOTE: USE WITH EXTREME CARE IF YOUR DATA DIRECTORIES ARE ON A NETWORK DRIVE!  NOTE: End users can't access databases during compact
  17. 17. 17 What makes your Notes Client START slow – ODS - Continued Impact examples  Startup time of a Notes 8.5.2 client with 3 ODS 20 apps in Notes data = 10 seconds  After ODS upgrade: 2 seconds  Reduced File I/O of your disks/SAN/NAS after ODS 41 to 51 upgrade by 60%  Removing 70% of all old files in Data directories on SAN/NAS = 45% less managed storage (backup) The bad news: There is no way to tell what is “out there”  3rd party tools or random inspections are highly recommended

  19. 19. 19 What makes your Notes Client START fast Eclipse Framework Performance Improvement Speeds up starting the IBM Notes client up to 65 % ONLY usable in virtual environments (e. g. Citrix XenApp, etc.) ONLY usable with a IBM Notes Roaming Solution
  20. 20. 20 What makes your Notes Client START fast - Continued Eclipse Framework Performance Improvement Example: Configuration of an IBM Notes 9.0.1 FP2 Client 1. With a non-admin user (OS + Notes) run an initial setup of the Notes client. 2. Start the Notes client 3x and wait then wait for each 2-3minutes 3. Shutdown the Notes client 4. Create the the following directory  c:ProgramDataIBMNotesDataCommon 5. Copy the workspace directory from %LocalAppData%IBMNotesData to c:ProgramDataIBMNotesDataCommon 6. Delete the following files/directories out of c:ProgramDataIBMNotesDataCommonworkspace a) UDM b) Logs  all but .prov2install c) cache  if available d) .metadata.pluginscom.ibm.collaboration.* e) .metadata.pluginscom.ibm.rcp.personality.framework f) .metadata.pluginscom.ibm.rcp.security.auth

  22. 22. 22 Agenda A Performance Boost for your IBM Notes Client Your IBM Notes Client: Version 9.0.1 What makes your Notes Client START slow What makes your Notes Client PERFORM slow Performance Tips and Tricks
  23. 23. 23 What makes your Notes Client PERFORM slow ODS of databases (again) Hardware (again) Notes.ini  EXTMGR_ADDINS = (not just) local virus scanners  Disable Notes “plugins“ like virus scanners etc.  they increase Network traffic by up to 200 – 250%! Data directory on the network vs.. fixed disk  Disk performance is the #1 bottleneck (think SSD vs. normal HDD ; 7.200rpm vs. 5.400rpm ; network drive vs. local fixed disk = latency/bandwidth limitation)
  24. 24. 24 What makes your Notes Client PERFORM slow – Port settings Port settings are included in the notes.ini  Type / Active / Encryption / Compression / Timeout Bad idea  LAN0 / COMx / DisabledPorts  should be removed Good idea  Use TCPIP according to the client type  PORTS = TCPIP  TCPIP = TCP,0,15,0,,12320,  Desktops  TCPIP = TCP,0,15,0,,45088,  Laptops  TCPIP = TCP,0,15,0,,12288,  Citrix / VDI  Riverbed !? Don‘t forget your Servers!
  25. 25. 25 What makes your Notes Client PERFORM slow - Continued Install types: Basic vs. Standard  Basic client starts up fast, Standard client, well … not so fast Roaming Users  Try replicating 80MB each time you logon to Notes before use! Connection documents  Pointing to outdated server names or IP addresses  Low priority connection documents, which can cause connectivity failures Location documents  IP addresses for mailserver  breaks Policies  Outdated mail and home server information  Outdated mail file path  Outdated Catalog server  In general: catalog.nsf  see next slide
  26. 26. 26 What makes your Notes Client PERFORM slow – The catalog.nsf problem User in Hamburg Sends Doc|DB-Link to user in Frankfurt Unfortunately, the user in Frankfurt does not open the database from a local server but from the one in Hamburg ... or even in Augsburg (Alphatbeth!)

  28. 28. 28 Make Notes faster = 1 Search for the file jvm.properties underneath [LotusNotesProgramDir]frameworkrcp (might be in subdirectory ...deploy)  Open it in a text editor  First line to look for is: vmarg.Xmx=-Xmx256m  Change it to e.g. vmarg.Xmx=-Xmx1024m (Maximum is ½ of physical memory; do NOT change it to more than 1024m regardless of how much memory you have) Change vmarg.Xms=-Xms48m to ¼ of what you changed Xmx to; e.g. if you changed vmarg.Xmx to -Xmx1024m then use vmarg.Xms=-Xms256m NOT recommended for production / normal end users; for admins & developers only!  But in reality, who else counts ;)
  29. 29. 29 Performance Measuring - Client Clocking NOTE: All of this should only be done on “ONE” client – slows down client, creates huge log files! Use the following to see and measure client performance CLIENT_CLOCK=1 CONSOLE_LOG_ENABLED=1 Debug_Outfile=c:debug.txt Debug_Console=1 DEBUG_TCP_ALL=1 (use only if needed) Fileserver or local disk Performance Debugging is virtually impossible If on >8.5 try adding DEBUGGINGWCTENABLED=16386 in Notes >= 8.5
  30. 30. 30 Performance Measuring - Client Clocking - Continued Client_Clock=1 leads to a debug file of the following format:
  31. 31. 31 Performance Measuring - Client Clocking - Continued OpenNTF – NRPC Parser Link: http://www.openntf.org/internal/home.nsf/project.xsp?action=openDocument&name=Notes%20RPC%20Parser Developed by: Jamie Magee, MartinScott Consulting LLC, US Andrew Magerman, Magerman Collaborative Software GmbH, Switzerland
  32. 32. 32 Performance Measuring - Network Latency Network Latency has a major impact on perceived client performance for users that (try to) work on server-side databases For example • Number of NRPC calls x (Latency Up + Latency Down) = how long it takes for a client to “talk something through” with the server • 30 Calls for opening the mailfile x (60 ms download + 60 ms upload) = 3.600 ms to talk through what's necessary to open the mailfile
  33. 33. 33 Performance Tuning – Understanding cache.ndk We've all been “advised to”/guilty of deleting the cache.ndk in an effort to cure Notes performance problems/symptoms  Some companies even delete cache.ndk on a scheduled basis HOWEVER, let us explain the impact of that on Notes performance ...  Increases traffic between client and server by 4,000% (forty times more traffic, yes) (10,000+% if the data directory is on a network drive)  The more databases end users use, the worse it gets  There is always a root cause – deleting cache.ndk only fixes symptoms (since 1992 I've had to delete my cache.ndk only once(!))  Let's look at some detailed traffic analysis for just ONE application (the mail file) of ONE user ...
  34. 34. 34 Performance Tuning – Understanding cache.ndk - Continued After deleting cache.ndk Keeping / NOT deleting cache.ndk 100 users = 150 MB vs. 3,7 MB 1000 users = 1.5 GB vs. 37 MB Excluding Fileservers!
  35. 35. 35 Summary Update/clean out your ODS, databases and templates and hardware Standardize whenever and however possible  This will save you hugely on support time/cost Keep your users version/fix packs current  Each release brings performance improvements but also resource demands Work around your inability to see clients  Write an inventory agent, login script, get a 3rd party tool Any challenge can be overcome with Knowledge and Tools  All client issues are solvable  Be careful with thinking that removing the client/going to the cloud solves everything
  36. 36. 36 The end is near ... Spending 30 minutes on Performance Improvements can be compared to a walk on the tip of the iceberg.
