Extremely long commit times

I've been using Bazaar to keep roughly 300 megs of text and binary files in sync across some computers. I chose bazaar because I have some non-techie friends that I'm distributing this to and it was easy to script some batch files for them to use. I'm using FTP to upload and download, and I usually get 800KBs down / 100KBs up on my connection.

Anyway, after a few commits, I've noticed the time to commit rising exponentially. The first load took a few minutes, which is understandable. The next few were short. Now, on revision 5, it's taking hours to commit a couple megabytes worth of adds. And/or stalling. I tried to retry it this morning (using the GUI) before leaving for work, and left it going all day. When I returned 8 hours later, it was sitting at 80%, and I saw zero network traffic in Task Manager.

I did do some uncommits the other day, and I worry that might have borked something up between the uncommits and the few times I killed the process and broke locks thinking it was dead.

I attempted to do a local commit, and it is done within a couple seconds. I was hoping this would speed up the remote commit to my webserver, but it doesn't seem to.

I'm just wondering if this is extremely unusual behavior because of the amount of data I'm working with, or if I have a corrupted index or something that actually is stopping my commit.

Thanks in advance for your help or advice.
