Inconsistent performance while updating working copy

I have seen inconsistent performance while updating working copy of a branch to head revision. No commits are happening to this branch. Some time it takes as long as 10 minutes and some times its complete under 5 minutes even though there are no commits to this branch.
Most of the time first update tried after couple of days takes time and subsequent updates are faster. As I explained before there are no commits happening to this branch, but commits are happening to other branches. My first thought was McAfee On-Access Scan is impacting performance but excluding McAfee Scan did not help. Any idea why would this happen ? Is there some kind of caching happening on client or server which could improve the performance of subsequent updates ?

Tortoise SVN Version: 1.6.16, Build 21511 - 64 Bit , 2011/06/01 19:00:35

Subversion Server Version: 1.5.7 running on Windows.

Thanks for your time.
