Layout

Controller
Controllers are classes that handle incoming browser requests
Retrieve data, and then specify view templates and return a
response to the browser
MVC requires the name of all controllers to end with "Controller"
Controller classes inherited from Controller base class
The Controllers Folder contains the controller classes

31. MAHEDEE.NET
31
Action and Parameters
Action is a public method
The controller defines action methods
Controllers can include as many action methods as needed
Action methods typically have a one-to-one mapping with user
interactions
Can take one or more parameter

43. Performance tuning and
scalability improvement tips!!
MAHEDEE.NET

44. • How affect in performance?
– Create pdb (program database – uses for debugging) files which
creates extra overhead.
– For this reason you may face timeout problem.
• Best Practice
– Always prepare release in release mode.
MAHEDEE.NET
46
Prepare release with release mode

45. • By default debug=”true” when you create a web application.
• It is necessary to set debug=”true” in development
environment.
• How affect in performance?
– If you set debug = “true”, application requires the pdb
information to be inserted into the file
– So results in a comparatively larger file and hence processing will
be slow.
MAHEDEE.NET
47
In Web.Config, Set debug=”false”

46. • Best Practice
– In deployment server, set debug = “false” in web.config
<system.web>
<compilation debug="false" targetFramework="4.5.1" />
</system.web>
MAHEDEE.NET
48
In Web.Config, Set debug=”false”

47. • Trace the application to monitor the executions of
application or a pages
• Uses for diagnostic purpose
• How affect in performance?
– Loaded extra information to the pages which degrades
performances.
MAHEDEE.NET
49
Turn off Tracing unless until required

48. • Best Practice
– Always set trace enabled = “false” unless or until you required to
monitor a page’s executions
<system.web>
<trace enabled="true" pageOutput="true" requestLimit="10"
localOnly="false" mostRecent="true" traceMode="SortByTime"/>
</system.web>
MAHEDEE.NET
50
Turn off Tracing unless until required

49. • Though, ASP.NET manages session state by default, we must
pay attention of session memory management.
• How affect in performance?
– When you store your data in in-process or on a state server or in
a SQL Database, it requires memory.
– It is also time consuming when you store or retrieve data in-
process or state server or SQL server.
MAHEDEE.NET
51
Carefully manage session state

50. • Best Practice
– If your page is static, it is recommended not to use session state.
In such cases where you don’t need to use session state, disable it
on your web form using the following directive:
<@%Page EnableSessionState="false"%>
– In case you use the session state only to retrieve data and not to
update, make the session state read-only using the following
directive.
<@%Page EnableSessionState ="ReadOnly"%>
– Consider carefully whether there is a need of the state server or
SQL Server mode.
MAHEDEE.NET
52
Carefully manage session state …

51. • Best Practice
– SQL Server session mode provides lower performance than state
server mode.
– Try to avoid keeping object in session. Since it requires serializing
then de-serializing which affected in performance.
– Use client-side state management than server side.
MAHEDEE.NET
53
Carefully manage session state …

52. • View State provides page level state management
• As long as the user is on the current page, state is available
and the user redirects to the next page and the current page
state is lost
• View State can store any type of data because it is object
type but it is preferable not to store a complex type of data
due to the need for serialization and deserialization on each
post back
MAHEDEE.NET
54
Disable View State of a page if not required

53. • How affect in performance?
– It increases the total payload of a page when submitted and
when serving request.
– Serialization and deserialization of the data is required when
submitting data and gets requested data.
• Best Practice
– Pages that do not have any server postback events can have the
view state turned off.
– The default behaviour of the View State property is enabled, but
if you don’t need it, you can turn it off at the control or page
level.
<%@ Page EnableViewState="false" %>
MAHEDEE.NET
55
Disable View State of a page if not required

54. • Finally block executes whether any exception occurs or not.
• How affect in performance?
– Sometimes application occupy resources where as it doesn’t
need it.
• Best Practice
– Always use a finally block to release resources like closing
database connections, closing files, disposing objects etc.
MAHEDEE.NET
56
Use finally block to release resources

55. • To show huge number of data in gridview, we cannot think
general way because it takes huge time to load.
• Best Practice
– To load grid view faster take advantages of paging, it shows small
subsets of data at a time.
– JQGrid is faster than asp.net grid view because it does
everything in client side.
MAHEDEE.NET
57
Use paging in grid view

56. • How affect in performance?
– The uses of web server controls increase the response time.
– Web server controls go to the server executes all of its life cycle
and then rendered on the client side.
• Best Practice
– Don’t use server control unless until required.
– Use HTML elements where suited.
MAHEDEE.NET
58
Minimizes number of web server control
