Improving CVS Performance?

[Vivek Venugopalan]

Hello
   We have a 2 GB repository running on a Linux system for over an year.  It
has a few thousand files (approx 10,000 ) and has started progressievly
become very slow.  We have a lot of tags (daily builds with a tag for each
build) and a few branches ( < 10).  Can you folks suggest what are the
things I can do to improve the overall performance of the system?

For example, a cvs update takes close to half an hour for the entire
repository on the local box itself.

TIA

Vivek
