ASP.NET Application Performance Considerations

ASP.NET Application Performance Considerations
Threading Efficiency	Thread pool tuning, Burst load, Creation of thread on per request, Blocking threads, Asynchronous calls
Pool Resources	Same connection string, Dispose or Close Call, Caching of pool resources, Obtain resource and release time
ASP.NET Pages	Page timeout, Page Size, Buffering, Page.IsPostBack, Partition Page Content, Expensive loops, Sever.Transfer instead of Response.Redirect
Server Controls	View State in Server Control, Deep hierarchies of Server Control
Data Binding	Page.DataBind, DataBinder.Eval
Caching	Dynamic data and static data, Memory limit, Caching right data, Refreshing cache, Cache API, Output Caching, Partial Page or Fragment Caching, Cache location, Kernel caching
State Management	InProc, StateServer,  SQL Server
View State	Disabling of View State, Number of objects in View State, Size of View State
String Management	Response.Write for formatting output, String builder for temporary buffers, HTMLTextWriter for custom controls, Large number of temporary allocations in short time
Exception Management	Global error handler, Number of exceptions thrown, Try/Finally on disposable resources, Code to avoid exceptions,
Data Access	Paging for large result set, DataReader vs DataSet, Requesting too much data
Security	Unwanted web server traffic, Authentication for anonymous access, Validation on client-side, Per-request impersonation, Caching sensitive data, Secure & non-secure content, SSL for selective pages, Absolute URLs for Navigation between HTTP and HTTPs, SSL Hardware, SSL Timeout
Deployment	Overhead of inter process and inter computer communication, Memory limit configuration, Tracing & Debugging, Web garden configuration, HTTP Compression
