12. SPMonitored Scope using (SPMonitoredScope monitoredScope = new SPMonitoredScope("Monitor My Code")) { LongRunningCall(); } SPCriticalTraceCounter.AddDataToScope(99, "What happened ?", 15, "Add additional info here"); 1 Critical 4 Exception (Watson) 6 Assert 8 Warning 10 Unexpected 15 Monitorable

13. DEV DASHBOARD Show you something cool

16. Object – Common objects and query results

17. BLOB – Commonly requested files put on WFE diskhttp://download.microsoft.com/download/7/F/0/7F069D0B-B6BD-4692-868B-E8555BB72445/SharePointServerCachesPerformance.docx

18. Caching

20. Enable output cache at site collection

21. Time to live vs. Check for Changes

22. Each page uses 2x+32 KB of memory

24. Enabled

25. Duration

26. Check for changes

27. Vary by custom , http header ,query string ,user rights

28. Cachability

29. Safe for authenticated use

31. Cache profile overrides for host header site collections avavilable for:varyByHeader varyByParam varyByCustom varyByRights cacheForEditRights

33. Via code e.g. PortalSiteMapProvider

35. Super User = web policy full

36. Not run as system

39. Best for infrequently changed css, js and images or large video

40. Video is normally buffered from SQL on WFE adding latency, BLOB cache is nearly equivalent of IIS direct

42. Extended web app has it’s own blob cache

43. Long url’s can break blob cache (server relative > 160 characters)

44. Can affect and be corrupted by IIS recycle if large

46. Delete file not cached, delete folder, rename/delete list, change permissions, title, description, add/remove content type = all files in list removed

47. Rename/delete web, add/remove permissions, change inheritance, add/update/delete roles = all files in web removed

48. Delete site collection = all files in site collection removed

50. Max-Age is optional , defaults to 86400 seconds (1 day)

52. User Centric

53. Blob Cache can help

54. Different libraries may have varied results for anonymous

55. _Layouts

56. Default SharePoint Max Age

58. Authors want it to change asap

59. Version CSS/Image to ensure reload

61. SPWEB is not therefore any item with embedded web like SPSListItemCollection can cause issues

63. CACHE Show you something cool

64. Logging

65. Dispose It’s complicated ! 64 bit helps hide the problem for longer Not just memory, SPRequest = 1:1 SQL connection http://blogs.msdn.com/b/rogerla

66. Do NOT DISPOSe SPContext.Current.Site SPContext.Current.Web SPContext.Site SPContext.Web SPControl.GetContextWeb(..) SPControl.GetContextSite(..) SPFeatureReceiverProperties.Feature.Parent SPItemEventProperties.ListItem.Web SPList.BreakRoleInheritance() Do not call list.ParentWeb.Dispose() SPListEventProperties.Web SPListEventProperties.List.Web SPSite.RootWeb Problems may occur when SPContext.Web has equality to the SPContext.Web.. make sure you dispose of SPSite and it will cleanup sub webs automatically SPSite.LockIssue SPSite.Owner SPSite.SecondaryContact SPWeb.ParentWeb SPWebEventProperties.Web

67. SHarePoint 2010 changes Microsoft.SharePoint.WebControls.SiteAdminsitrationSelector.CurrentItem 2007 must dispose, 2010 don’t Event Recievers Properties.OpenWeb() – 2007 dispose of SPWeb SPItemEventProperties.Web instead and no dispose

68. Dispose Monitoring SPDisposeCheck ULS Logs Memory Internals SQL Server Connections

70. PortalSitemapProvidor if data is low and relatively static

71. SPListItemsGetDataTable and SPQuery for list data retrieval

72. For each is the last optionhttp://office.microsoft.com/download/afile.aspx?AssetID=AM102377231033

73. Content Iterator SPQuery query = new SPQuery(); query.Query= "<Where><Eq><FieldRef Name=quot;MyIndexedFieldquot;/><Value Type=quot;Textquot;>FieldValue</Value></Eq></Where>" + ContentIterator.ItemEnumerationOrderByNVPField; ContentIterator ci = new ContentIterator();ci.MaxItemsPerQuery = 500; ci.ProcessItemsInList(query, delegate(SPListItem item) { // Work on each item. }, delegate(SPListItem item, Exception e) { // Handle an exception that was thrown while iterating. // Return true so that ContentIteratorrethrows the exception. } );

75. Row and Column Throttling

76. Http Request

77. Unique Permissions

79. Default is 5000 items, beware of table locks if you change

80. Overrides for auditors and administrators only in OM

81. Machine admin overrides all throttle limits

84. Fallback query for subset of data

85. Enabled for all lists in the web once metadata navigation feature is enabled

87. Health Score Health score is given back as part of the http headers X-SharePointHealthScore 0 is healthiest, 10 is the worst Office applications such as workspace use adaptive sync based on health score Consider use if performing high load operations remotely

88. Health Score

90. Caching

91. Logging

92. Object Disposal

93. Querying
