Building on Fedora 6

Wed May 9 12:03:02 UTC 2007

It's worth mentioning somewhere in the instructions that "make -j"
doesn't work when building openjdk.  The actual parallelism is
supposed to be controlled by HOTSPOT_BUILD_JOBS, but it doesn't seem
to be very effective.  On a dual-processor box with
HOTSPOT_BUILD_JOBS=4 I get:

Control build finished: 07-05-09 13:00
1729.91user 166.63system 23:53.03elapsed 132%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (1002major+40812683minor)pagefaults 0swaps

which is not bad, but it would be nice to increase the parallalism.
