Hi,
I'm trying to optimize an ASP.NET 2.0 app where, with a load of 100 users, the CPU usage on the web server is a reasonable <20% but the db server (SQL Server 2005) often goes up to 100% and never below 20%. When viewing the Performance Monitor counter SQL Server :General Statistics/User Connections this shows that there are 50-65 connections. When the number of connections go up the db server's CPU usage also goes up along with web page response times.
When viewing the Sql server Activity Monitor it, for all connections, always says that the Login Time and the Last Batch are the same. This has got me wondering if no connections are pooled and that all connections always are closed and reopened and that would explain why the db server is so jammed.
Could someone give me some pointers as what to check to find optimization points.
Regards,
Mathias
Which operating system is running on your server?|||Hi Mathias,
Please check in your connection string to see if pooling has been turned off.
If it is on, you can try to increase the connection lifetime and the min pool size, to make sure that the connections are available for using.
