Re: heh

It'll be even more obvious to you when I describe how I measured the
difference. :-)

I modified svndiff-test to leave out the base64 encoder and and the
actual output of the diff, then tested that on two versions of a 6 MB
Win32 optimised executable, then measured user time (by the way, the
un-base64ed svndiff size would've been about 1.5 MB, in 86 windows).

The speedup (using gcc -O2 optimised code!) was 5-15%, depending on
platform -- and txdelta->svndiff and file reading is included in this
time, so I suspect the difference for the actual vdelta encoder is even
larger. Take into account the fact that we calculate the hash -- with
key length of only 4 bytes -- exactly *once* for every lookup.

Let's just say that I was "mildly" surpriesd by the results ...
