how multiple cpu are handled in "iRules Runtime Calculator" document
Hi iRule Team,
I have a question to the "iRules Runtime Calculator" (*)
http://devcentral.f5.com/Tutorials/TechTips/tabid/63/articleType/ArticleView/articleId/123/iRules-Optimization-101--05--Evaluating-iRule-Performance.aspx
My customer had an irule that work in v9 and the performance was acceptable. After we migrated to v10.2.0 we faced a performance issue with the command (1). We could be able to improve the performance by rewriting it to (2).
1) set ppass [ class get -nocase ProxyPass $query_value]
2) set ppass [ class search -element ProxyPass equals [string tolower $query_value]]
We have now couple of questions in regards to (*).
1) When using the iRules Runtime Calculator Excel sheet provided by F5, could we multiply the results by 4 when we have 4 CPU devices? In the Excel sheet only the CPU cycles could be filled in, not the CPU count.
2) The results in the "Max number of requests" table refer to the HTTP requests/sec or to the Active connections? In case we have Max 12000 HTTP request on the production box and the results we got in the sheet are average 21000 requests, are we save to use the iRule even with ASM enabled?
FYI, we have still a case at Support in regards to he performance issue: C812254.
Looking forward
Rado
