I would not recommend that. With a merge factor that high you may
run out of file handles, and, moreover, I doubt that disks are very
efficient when reading from that many streams.
Running out of filehandles is a solvable problem because you can set
ulimit -n to whatever on OS X -- and you pretty much have to, since
the default is 256.
The streams issue is more complicated. N-way merges from disk tend
to be IO-bound. The best I can do is try a couple numbers and see
what works. IIRC, the number 100 has gone by on the Plucene mailing
list as a good value.
