moving indexes onto another partition

Hi
From several weeks I suffer poor performance of my SQL Serv (as backend to
the web application).
I heard that sometimes splitting database to different hard disk could raise
performance. But in my case I have got only one HDD devided to 2 partition -
my question is: if it is good idea to migrate tables or indexes to anther
partition - does it make sens?
Or maybe thare is another solution to my problem - connected mostly with HDD
queue legth. So I could say that all the delay in answers are connected with
poor HDD performance.
Best Regards
Darek T.It does not help to move the indexes to the other partition: it is still the
same physical disk drive.

vast majority of performance problems can be fixed by rewriting queries or
adding indexes.
Beyond that, you can only add physical drives to distribute the read/writes.
