Hi
When using CVS at the office (local LAN, 10/100 mixed network), performance
is not an issue.
When I use eclipse/CVS (Win/XP pro) from home I notice that most of the
wall-time of a CVS transaction is spent in 'Authentication'.
The connection at the office is ADSL (128KB outbound, 512+KB inbound).
My connection at home is a cable modem which typically downloads at T1
speeds or greater.
The application I'm working on has multiple projects. When I select them all
(40+) and perform a 'global' CVS operation (ex: refresh branches) the
operation which takes at most a few minutes in the office, takes 30-60
minutes from home.
As far as I can tell, most of the delay is due to repeated authentication.
It seems CVS is authenticating me for each project it access rather than a
single authentication when the request starts.
My questions:
1- Is my interpretation of what is going on correct?
2- More importantly, how can I solve this problem? I would like the
performance from home to be in the same ball park as my work at my office.
-TIA
David

Hi
As a follow-up, I took a closer look at my CVS connection in eclipse.
I'm already using 'pserver' which means that the split of the read/write
connections suggested by the release notes will not help. I really do need a
mode which does a single global validation once, then performs the selected
operation on all the selected projects rather than doing an authentication
on each project selected.
-TIA

David,
The use of a connection per project is related to the Team archtitecture
of Eclipse. It is also typically how CVS works. Having said that, it
would be feasible to perform the operation over a minmal number of
connections. Please log a feature request against Platform VCM.
