I guess I could try to contribute to IntelliJ (to the SVN plugin) to implement similar functionality as TortoiseSVN (i.e. --limit 100 and offer buttons to get more), or to load the history in the background and show it while it comes in. There are actually two IntelliJ issues open for this "improvement": http://www.jetbrains.net/jira/browse/IDEA-11092 and http://www.jetbrains.net/jira/browse/IDEA-22245. But I'd really, ultimately like this to be solved by the SVN server (all other solutions are patchwork).

Is it possible that your server is I/O bound? Logs are stored in
revprops, one per revision. So if you're pulling the history for a
large range of revisions, you're doing a lot of access on many small
files - some filesystems are very poor in this usage scenario.
