Biggest number of revisions under FSFS?
As I'm aproaching 200k revisions in a repository, I was wondering. In
FSFS, each commit is one file. What's the biggest number of revisions
people have with FSFS out there?
I'm currently using 1.4.3, with ext3 FS + dir_index option.

I sure hope not!

You probably didn't have a properly configured DB_CONFIG file when doing
the load with the BDB backend.

I don't remember the dump time, but the load time for a BDB repository
with ~60k revs and a ~3GB dump file took something like 10-12 hours.
It was significantly shorter for a FSFS repo, only about 5 or 6 hours.

In my case, dumping 150k revisions (repo is 50Gb large) takes about 3h
and something on a core2duo E6300, 2Gb RAM, with a common sata disk.

Does anyone know how long a dump/load would take with something like that?

KDE is up to 655k:

Subversion 1.5 will have repository sharding in it, so not all revisions
will be placed into the same directory.

Assuming they're using FSFS - the repository is over 4 years old, at
which point the default was BDB (they could have converted at some
point, of course).
I seem to recall hearing that the limit (for FSFS) was dictated by the
host filesystem's number of files per directory.

The repository at apache.org is currently over 530k revisions...
http://svn.apache.org/viewvc/
You could ask them if they're experiencing any problems with that.
