Performance Tuning and Monitoring
Performance is low due to the user code
So we can find out that thing using the below
Http .sys listener in kernel mode is passing the requests to websites app pools and worker process of app pool will execute the requests.
if the worker process will get the requests of type html pages, then the performance will be high.
This is best case for iis.
IIS will be worst when executing the following
IIS performance will be fast when it executes the MS code
It will be slow when it executes the user code
Means Bad performance in IIS is not iis fault, its developer fault.
When the server configured for iis is also having the sql server, my sql, active directory etc… Then the iis needs to share the memory with them
1…WCAT: it will send the numerous static web page requests to IIS
we can do test like this
Check the sermon’s and by running wcat tool to send requests to IIS
and do the test in the other server
when u r running wcat , don’t use asp,asp.net,php etc.. only use html static request
in the perfmon.msc add the counter like w3wp, wap (app pool) and checks the performance
in the other server check the performance for user code , if there is huge difference ask the dev team to fix the code
2… IIS SCOM PACK:
—->check the graph in the perfmon.msc, if processor is taking high and iis is taking low then it means processor not enough to handle the iis request or there are some other resources to that are using processors
check the task manager check the processes that are consuming more memory than worker processes
