Adam Heath commented on VFS-159:
--------------------------------
Uncertain about how hotspot is implemented. My testing involved calling my
processing chain 10000 times. However, a lot went on under the hood. Each
call may have 300 FileObjects that it makes use of(it does extension
resolution; the internal paths have no extension, and it tries to find the
correct file by comparing with a list of configured extensions). It also does
a check for attributes on each intervening directory. Then, each
file/directory in use has several attributes that are looked up(using that
foo@/name syntax I mentioned elsewhere).
Each of these speedup patches was done with a noticeable improvement. It's
been a while since I did that testing, and since it was so iterative, I didn't
keep before/after pictures.
