The machine is Windows 2003 server SP2 with 8 GB RAM, Dual Quad core CPU and SQL 2000 SP4 and .NET Framework 3.5 with SP2.
We run CuteChat 5.0.
All these people login at 10:00 AM - 4:00 PM and we have see the the data transfer is whopping 5 GB with just simple chat.
We observed that the file ChatAjax.ashx consumes 3.5 GB plus.
We are facing high 100% CPU utilization due to w3wp.exe due to logging of 250 users when there would be around 150 odd users
the usage comes down to 50-60%. We setup a Web Garden with 4 worker processes but only one of the process takes most of the load and the load is not evenly distributed.
Please help us identify the issue at the earliest.
