Hi friends,
In this article I will tell you how to improve performance of
our asp.net website. There is very small setting but it improves huge
performance.
In the web.config file you can do the following setting
1)
Set debug=false under compilation as follows:
<compilation
default Language="c#" debug="false">
3)
Always check Page.IsValid when using Validator Controls
4)
Use Foreach loop instead of For loop for String Iteration.
5)
Use Client-Side Validation. (but not all the time you have to validate even on
the server side)
6)
Check “Page.IsPostBack”. To avoid repetition code execution.
7)
GIF and PNG are similar, but PNG typically produces a lower file size. (True,
but some browsers not supporting PNG format)
8)
Use the AppOffline.htm when updating binaries
9)
Turn off Tracing unless until required. (by default it's off, use on the pages
where it's required)
<trace
enabled="false" requestLimit="10"
pageOutput="false" traceMode="SortByTime"
localOnly="true"/>
Some times after doing
this setting also ASP.NET Page is very slow. What will you do to make it fast?
1. Find out which is slow, is it the application
or the database : If the page is executing SQL queries or stored procedures,
run those on the database and check how long do they take to run. If the
queries are taking most of the time, then you know you have to tune the queries
for better performance. To tune the queries, there are several ways and I have
listed some of them below.
a) Check if there are indexes to help the query
b) Select only the required columns, avoid Select
*.
c) Check if there is a possibility to reduce the number of joins
d) If possible use NO LOCK on your select
statements
e) Check if there are cursors and if you can replace them with joins
2. If the queries are running fast, then we know
it is the application code that is causing the slowness. Isolate the page event
that is causing the issue by turning tracing on. To turn tracing on, set Trace="true" in the page directive. Once
you have tracing turned on you should see trace information at the bottom of
the page as shown in the image below. In this case Page Load event is taking
the maximum time. So we know, the code in Page_Load
event is causing the issue. Once you look at the code, you should be able to
nail down the issue.
Happy Programming ! !
