Excessive Memory usage

I'm running obnam (1st run) on a decent sized (2.8T) volume. It's been running for days and beyond being slow, it's using a good bit of memory. This does not seem reasonable. Is there something I should tweak?

Thanks

I have not benchmarked Obnam's memory usage for a while, so I don't know if that is unexpectedly large. It's certainly larger than I would like, though. You can try different sizes of the following settings:

node-size
upload-queue-size
lru-size

If you change the node size, you'll need to remove the repository and start over, since it only affects new instances of the in-repository data structures, so it's probably best to start by trying different values for the other two settings.

--liw

I've reduced the default values for lru-size and upload-queue-size. Obnam should now be using a lot less memory. --liw
