Our largest single repository is around 150G currently. No limit
that I know of. The biggest performance killer I have found is
a large number of files in a single transaction, not the individual
size of the files.

Using the http:// protocol, you will be limited to around 2G for
a single compressed diff of a file in a transaction. Even with
apr >= 1.2.x. The transaction itself isn't limited.
(The svn client sends a negative value in the http header during
 the txn causing the problem. Last time I tested on Solaris,
 Linux and Windows using svn 1.5.1, neon 0.28.3, and apr 1.2.12.)

Using the svn:// protocol I haven't found a limit yet, but the
largest single file I have done is around 6G.

This all assumes your svn server is using apr >= 1.2.x and
it has been enabled for 64-bit file access.
