workspace performance in CVS

[Bala]

Hi,

We have a tool which is written over CVS and exposes all
functionalities that CVS to a set of developers in our organisation. We
have noticed that it takes a long time for cvs update to create files
in the user's workspace when they start their work.  Right now, the
basic options available from the tool allows developers to create a
workspace from files in main branch directly to their home directories.
The CVSROOT is roughly 1G and it takes close to 2 mins for the
workspace to be created.

We have been thinking about various alternatives to optimize the
workspace creation such that developers dont need to wait for a
indefinite time to get started with their work. Has anyone faced such
problem and is there a better way to solve the performance ? Please let
me know.
