Tips and Tricks for Faster ASP.NET and MVC Applications


    http://www.slideshare.net/SarveshKushwaha/tips-and-tricks-for-aspnet

     Summary of this,

    Design and Architecture play a major role before you start thinking about performance, if it is     started with a sound design and architecture in focus with best practices which are obvious then you might not hit major bottle necks. Design for failure and Cloud applications follow this principle.  

1.Static resources should be Cacheable
   <system.webServer>
<staticContent>
 <clientCache cacheControlMode="UserMaxAge" cacheControlMaxAge="365:00:00" />
</staticContent>
   </system.webServer>
2.Bundling and Minification
3.Use ViewState when its necessary
   EnableViewState="false"  in a text box control
   Page level - <%@ Page EnableViewState="false"%>
   in web config - <pages enableViewState="false"/>
4.Use effecting pages
5.URL Compression - 
   <system.webServer>
<urlCompression doDynamicCompression="true" doStaticCompression="true" dynamicCompressionBeforeCache="true"/>
   </system.webServer>
6.Use sprite images   - you can use nuget packages to do this
7.Image Optimization - you can use Image Resizer nuget package also allocate space for image using <height/> <width/>
8.Always deploy in Release mode  Set debug="false"
9.Use client side validations
10.Remove unnecessary HTTP Headers -
Removing X-AspNet-Version - <httpRuntimeenableVersionHeader="false"/>
Remove X-AspNetMvc-Version - in Global.asx.cx file - MvcHandler.DisableMvcResponseHeader=true;
Remove Server Http Header - https://blogs.technet.microsoft.com/stefan_gossner/2008/03/12/iis-7-how-to-send-a-custom-server-http-header/
Remove or Edit X-Powered-By - IIS7 Manager > Http Response Header > Edit or Remove
11.Pipeline Optimization - Remove unnecssary Http Modules
12.Use Content Delivery Network
13.Dispose Objects Manually - use a USING statement
14.Effective use of Jquery Ajax - async data fetching, not too many, on scroll load data
15.Use Asynchronous methods to get multiple data
16.Turn of tracing
17.Instead of Response.Redirect() use Server.Transfer() or Server.TransferRequest()
    Response.Redirect simply sends a message (HTTP 302) down to the browser.
    Server.Transfer happens without the browser knowing anything, the browser request a page, but the server returns the content of another.

18.String Management Use += operator or String.Concat() if number of appends known else use StringBuilder
19.ASP .NET literal and lable are different
20.Remove Blank Space and lines from HTML
21.Use performance tools - DotNetMemoryProfiler, SQLServerProfiler -
   YSlow, Speed Tracer, Firebug, Chrome Dev Tools, Page Analyzer, Pingdom, Fiddler

API design best practices

API Design summary 1. Use two base URLs per resource 2. Keep verbs out of your base URLs 3. Use HTTP verbs to operate on the collections and elements 4. Be consistent either use plural nouns or singular nouns 5. Use concreate names rather than abstract names     An intuitive API uses plural rather than singular nouns, and concrete rather than abstract names 6. keep your API intuitive by simplifying the associations between resources, and sweeping parameters and other complexities under the rug of the HTTP question mark. Handling errors Errors boil down to Everything worked - ok The application did something wrong – client error The API did something wrong – server error In summary, be verbose and use plain language descriptions. Add as many hints as your API team can think of about what's causing an error. eg: HTTP Status Code: 401 {"status" : "401", "message":"Authenticate","code": 20003, "...

DB Connection Issues

1. Application gives "1c86bdf0 SharedPool I J2CA0086W: Shareable connection MCWrapper id 686bbdf9 Managed connection com.ibm.ws.rsadapter.spi.WSRdbManagedConnectionImpl@6156bdf9 State:STATE_TRAN_WRAPPER_INUSE" message when trying to do a db update within loop which is querying a view and carrying out some operations. In IBM this problem is documented under the topic " Application hangs with prior J2CA0086W warning messages" The solutions are  1. The application must be modified to use serial reuse or 2. The connection pool can be changed to unshareable. Shareable connections are not allowed within a local transaction containment boundary. The above scenario suggests a possible problem in the application logic and how it is using the connection code. The J2CA0086 message is telling you that your application is using a shared connection in a LocalTransaction. Since the connection is enlisted in a Local Transaction, and not a Global Transaction, di...
