Does Git on MSWindows use a dentry like cache in user land to speed up filename lookups? Does it use a stat() equiv cache? Is there a reason that such caches weren't put into ntoskrnl.exe? Would you be able to give us a brief list (say top 5) of changes that sped up git on windows? And which ones had the most effect on super sized monoreops. Thanks!
I have seen poor performance of git on Linux in very large repos, so I'm not super convinced that the dentry cache magically makes things better.
In particular, if my repo is big enough, I often don't have the entire tree in memory (because I'm doing other useful things with memory and caches got evicted). core.untrackedCache makes things a little better, but it's still not great.
