As Daniel mentioned to me on irc, subversion doesn't use threading internally, so things like client side commit processing and merge operations are done one file at at time IIUC.
Over in the openoffice podling we have a use-case for a 9GB working copy that regularly sees churn on each file in the tree. commit and merge operations for such changes take upwards of 20min, and I'm wondering if there's anything we could do here to reduce that processing time by 2x or better by threading the per-dir processing somehow. Thoughts?
