18. Web Service Enhancements

19. Obfuscator

20. Microsoft ACT ACT is a web stress tool designed to simulate a high volume of HTTP requests Test applications or web services as they are being developed Discovers bottlenecks and provides performance information Not a multiple client tool (developer only)

21. Creating an ACT test Manually create tests Browser recording tests Setting the test properties Simultaneous browser connections Run time or iterations

22. Adding dynamic data Changing request data makes the simulation more accurate You can modify any part of the request or response Query strings Controlling the current user Cookies ASP.NET view state

23. Security Authentication schemes supported: Basic Integrated Windows DigestPassportForms Encryption types supported Secure Socket Layer

24. Using SOAP SOAP request can be obtained from the web service help page You’ll need to format the SOAP request to be properly encoded Utilize Visual Studios built-in macro recorder

25. Creating an ACT Test

26. Analyzing the results Getting performance information is an iterative process Stand-alone ACT interface has better reporting Saturation point Processor, memory, disk, network, backend Response time: TTLB of 10,000 ms Watch client CPU utilization!

27. Decreasing requests/second

28. MHz cost formula for a Page Mhz Cost = N * S * avg (CPU) / avg(RPS) Where: N = Number of Processors S = Speed of Processors CPU = Processor: % CPU Utilization RPS = ASP.NET: Requests/Second

29. MHz cost formula explained A test using a 2 processor web server achieved 80 requests per second, with the processors 70% utilized So, this works out to … 2 processors * 700 MHz = 1,400 MHz 70% CPU utilization = (1,400) * (0.70) = 980 MHz available to use 80 ASP requests per second 980/80 = 12.25 MHz per ASPx request

30. Performance counters Processor Processor, % CPU Utilization Memory System, Context Switches/Sec Network bandwidth Network interface, Bytes Total/Sec Disk Physical Disk, % Disk Time_Total Backend resource ASP.NET, Requests Queued

31. Performance tips Try to use a dedicated web server for testing Use SQLDataReader for SQL Server data access, not the OleDB reader Turn off debug mode when not using Turn off view state where its not needed Turn off session state if not needed

32. Performance tips (cont.) Pre-batch compile - request a page from the web application Running code in both managed and unmanaged worlds is expensive Cache items that have a long expiration Use a Repeater instead of a DataGrid control – its less expensive

33. web app Making Your.NET Apps More Reliable A New Architecture for IIS6 GOAL: enable complete app isolation from other web apps and core web server Web service in INETINFO split out to do this: HTTP.SYS: kernel mode listener and request router WAS: config and process manager W3WP.exe: where web apps are processed Multiple W3WP.exe’s WAS W3WP.exe web app HTTP.SYS kernel W3WP.exe W3WP.exe

34. Making Your.NET Apps More Reliable Application Pools Can create 1 or more application pools Each served by 1 or more W3WP.exe’s. Each W3WP.exe serves only 1 pool. Reqs routed directly to pool by HTTP.sys Isolate apps based on: Site/CustomerFunctionalityReliability

35. Making Your.NET Apps More Reliable.NET Application Domains vs Application Pools Application Domains Lightweight CLR unit of isolation One app domain per IIS application Combine w/W3WP.exe’s to achieve high scalability and isolation ASP.NET manages app domains independently Recycled within a single process Can have private components, session variables, etc. HTTP.SYS W3WP.exe ASP.NET WAS App pool W3WP.exe ASP.NET AppDomain AppDomain AppDomain AppDomain AppDomain AppDomain AppDomain AppDomain Application Pool W3WP.exe ASP.NET App pool

36. Making Your.NET Apps More Reliable Periodic Process Recycling What is it? Periodically restart applications based on: Uptime # of requests Scheduled time Memory consumption On-demand Why use it? Refresh apps to ensure availability Prevent bad apps from taking over the system

37. Making Your.NET Apps More Reliable Dynamic Kernel Caching GET http://www.acme.com/store/sproketcatalog.aspx RequestResponse WithoutCacheWithCacheRequestResponse

38. Summary More “in the box” Developer productivity enhancements Java developers can develop for.NET platform Web Service Enhancements Stress test your ASP.NET applications Protect your intelectual property IIS 6.0
