Dev Server Slow

Hi All,

Im working on ECC 6.0.

OS is windows 2003 server and database is Ms SQL 2005. RAM is 4 GB.

Had set pagefile four times RAM and its static.

My DEV server at times becomes very very slow so i chk

- CPU usages in task manager thts also hardly 5-10%

- there is no locked process also.

- when I chk in ST02 all the hit ratio is above 99%.

- there is hardly 15-20 users logged in

Can any one plz tell me wht else could be looked into to make server work at good speed.

Many thanks

Mani
