source operating system landscape." This document [.pdf] describes all the changes.

"I did a simple mysql super-smack benchmark test on a Intel XEON machine,
the CPU has 4 cores:
CPU: Intel(R) Xeon(R) CPU 5130 @ 2.00GHz (1997.03-MHz)
I have set environment variable LIBPTHREAD_YIELDLOOPS to 30 and start
mysql server:
setenv LIBPTHREAD_YIELDLOOPS 30
/usr/local/etc/rc.d/mysql-server start
and repeat doing
#super-smack ./select-key.smack 10 20000
The result is very surprising:
# /usr/src/tools/tools/ministat/ministat normal.txt yield_30.txt
x normal.txt
+ yield_30.txt

(Student's t, pooled s = 1478.47)
it seems over 44% performance is improved.

This is amazing now!
Kriss Kennaway, could you try it out and update the benchmark graphs?
