Use Server Cache Control to Improve Performance - apache web server settings for optimized caching with configuration files

by camel & 3 others
Caching is the temporary storage of frequently accessed data in higher speed media (typically SRAM or RAM) for more efficient retrieval. Web caching stores frequently used objects closer to the client through browser, proxy, or server caches. By storing "fresh" objects closer to your users, you avoid round trips to the origin server, reducing bandwidth consumption, server load, and most importantly, latency. This article shows how to configure your Apache server for more efficient caching to save bandwidth and improve performance. Caching is not just for static sites, even dynamic sites can benefit from caching. Graphics and multimedia typically don't change as frequently as (X)HTML files. Graphics that seldom change like logos, headers, and navigation can be given longer expiration times while resources that change more frequently like XHTML and XML files can be given shorter expiration times. By designing your site with caching in mind, you can target different classes of resources to give them different expiration times with only a few lines of code.

To benchmark a web server the time it will take to give a page is not important: you don’t care if a user can have his page in 0.1 ms or in 0.05 ms as nobody can have such delays on the Internet.

15 Seconds : Tuning Up ADO.NET Connection Pooling in ASP.NET Applications

by brianwaustin (via)
Opening a database connection is a resource intensive and time consuming operation. Connection pooling increases the performance of Web applications by reusing active database connections instead of creating a new connection with every request. Connection pool manager maintains a pool of open database connections. When a new connection requests come in, the pool manager checks if the pool contains any unused connections and returns one if available. If all connections currently in the pool are busy and the maximum pool size has not been reached, the new connection is created and added to the pool. When the pool reaches its maximum size all new connection requests are being queued up until a connection in the pool becomes available or the connection attempt times out.
