Question

Slow web app login

Asked by: ryankahan

Hi,

I have a web app (written in C#, ASP2, Ajax...) using SQL 2005 Expess as db and IIS on Windows2003 SP2 running on a HP ML110 with 4GB RAM and SATA2 HDD's.
When I hit the login to access my web app (remotely/local) on my server, it takes up to 30secs to open.
I have an exact same install to the above on another box that login in 2secs max.

I have been running perf mon for a couple of hours now and notice that when I hit login on the web app the Memory-Pages/sec, SQLSrver:Transactions flat line at 100%.
At this point it seems that hardware is NOT an issue at all, but more an SQL/IIS issue (I am guessing!).

Please help!

Thanks.

Hannes.

while submitting the login details, check is there any block is created in sql server.

switch on the SQL Server profile tracer and check which part is taking more time. If all the above test result is positive then you need to check Network.
