Web Site Performance


We have a web site which has over the past 12 months become very busy and is now handling about 50,000 transactions each day.

I have been watching the server performance and the CPU spikes a lot so I need to find any inefficiencies in the code which could affect performance. Are there any tools out there to help me with this ? I need to see where in the code the spikes are happening, how many conncurrent db connections are happening etc ... This will allow me to root out any areas of the application which are inefficient and will cause increasing rpoblems as we scale our business ...

Thanks so much,

You can install Fiddler from http://www.fiddler2.com/fiddler2/ and start exploring and fixing your site's performance issues.

I hope it helps.
I will try to change your directions :)
if you server is not very old, try to check the TOE (TCP offloading) feature on NIC cards, enabiling this will releafe the CPU, also think about faster HDD with raid or SSD, CPU spikes can be a symptom for Disk IO problem.

windows performance monitor, performance counter are very helpfull, there is specific counters for ASP.NET and SQL...  that can be very helpful, Microsoft Published doucumentions about those counters and how to analyze it. including the one you mentioned,

good luck
