If the commit backend has high latency, it can make a big difference to read files concurrently. This patch updates the working copy code to do that in the update code (when reading files from the backend to write to the working copy). Because our backend at Google reads files from a local daemon process that already does a lot of prefetching, this patch doesn't actually help us. I think it's still the right thing to do for backends that don't do the same kind of prefetching. It speeds up `jj sparse set --add` by >10x when I disable the prefetching in our daemon (our `Backend::concurrency()` is 100). |
