A reservecache of 16 makes it behave quite nicely. Snappy performance.

Snappy on both the id3lib and libid3tag versions? I'm curious because my id3lib performance is much worse than my libid3tag performance. I kinda would like to lean towards libid3tag because of less executable bloat, and the fact that it performs better for me, but if you're seeing something different, I'd like to figure it out.

Incidentally, how much did you torture-test 1.01? I'm curious as to why you wouldn't have seen crappy performance in 1.01 without any ReserveCache. When I ran with no ReserveCache on 1.01, it was a complete dog.
