It's known and oft-lamented. NTFS just doesn't handle this scenario
well - it's probably one of the reasons FSFS sharding was introduced

How's the checkout performance with a command-line client on that XP
box? It could also be your on-access virus scanner, and testing w/ the
command-line client may help diagnose that.
