Hi Nouha,
Based on the relative size of the repositories, one might expect that the
larger repository would take about twice as long to export. So clearly
something is weird here.
You'll still need to provide more details:
- Are the types of files in the two repositories different?
- Are you running a virus scanner on the client?
- Have you timed the command, to find out how much system, user, and
real time is being spent?
- What command are you using to export? (Are you exporting from a
working copy, or directly from the server?)
- What OS & version thereof are you using on the client?
- Have you observed the problem with other clients / OSes?
- Does an export take the same time as a checkout?
- Have you tried doing a export of the repository on the server? Does it
show the same time discrepancy?
Somehow, you need to establish enough information to identify whether the
source of the problem is the server, the client, the network, or the
protocol.
For example, the client could be running a virus scanner that goes nuts for
your 30K files repository. Or it could be that something is unreliable
about your network, but only manifests itself with a few files from your
30K repository.
