Random Logic l Forum.NET l ASP.NET performance Forum.NET 5 th Meeting ● March 2006 By Yaniv Sharon

Random Logic l Forum.NET l Agenda  What is Performance tuning  Problem description  Viewstate  Mass data handling  ASP.NET controls  Excel exports  Zipping content  Compressed output

Random Logic l Forum.NET l What is Performance tuning? Monitoring and analyzing the net performance of a system and adjusting its configuration to obtain optimum performance.

Random Logic l Forum.NET l What is Performance tuning? -In computing, optimization is the process of modifying a system to improve its efficiency. The system can be a single computer program, a collection of computers or even an entire network such as the Internet.

Random Logic l Forum.NET l Problem description -Slow access of FE & BO users -Physical line limitations (BO) -Multi posting of forms (BO & FE)

Random Logic l Forum.NET l HTTP REQUEST (GET) Process Request RESULT 500ms 200ms 100ms 1.Get 200ms 2.Process 100ms 3.Result 500ms Total 800ms

Random Logic l Forum.NET l HTTP REQUEST (GET) Process Request RESULT500ms 1500ms 3000ms 1.Get 4500ms 2.Process 3000ms 3.Result 500ms Total 8000ms HTTP REQUEST (GET) 1500ms

Random Logic l Forum.NET l ASP.NET controls  Control names  Single object controls  Multi-objects controls (tables etc)

Random Logic l Forum.NET l Viewstate -The Viewstate input -Minimize Viewstate usage -Using server-side solutions -Re-generating the data -Session object (higher server utilization, less network traffic)

Random Logic l Forum.NET l  Using asp.net httpModules, to add compression to generated html: Web config:  Supported by IE5.5+ Content compression

Random Logic l Forum.NET l Compressed output -IIS supports compress output -IE 5.5(?) and higher -Not fully supported in all browsers -Good for BO -Images -Saves 30%-40% of traffic

Random Logic l Forum.NET l Excel exports -Most exports are done with exporter objects. -Pros: -Styled output -Cons: -Slow processing -High Cpu utilization (server side) -Limited line numbers (5K)

Random Logic l Forum.NET l Excel exports -Export using the response object -Pros: -Faster -Line number limit is 64K -Minimum cpu usage (server side) -Cons: -No styling

Random Logic l Forum.NET l Zipping content! -Determine what content can be zipped (excel exports) -Use zip component to zip the output -Save 90% of network traffic -Save 90% of download time
