Are you just guessing or have you actually seen the delay I'm talking about disappear as a result of this (or as a result of anything else for that matter)? Because I've already done this (yes, entirely, even the kernel mode drivers) and it's definitely not the issue.
There was a release of subversion back in the day that reduced the number of files that were opened during a repo action like pull, and the number of times any one file got opened. On Linux it ran about 2-3x faster. Very nice change.
On windows it was almost 10x faster. On the project where this change was released, my morning ritual was to come in, log on, run an svn pull command, lock my screen and go get coffee. I had at least ten minutes to kill after I got coffee, if the pot wasn’t empty when I got there.
Windows is hot garbage about fopen particularly when virus scanning is on.
