Hi Manfred,
Just wanted to let you know I tried your patch-spinlock-i386 patch on
our STP (our automated test platform) 8-way systems and saw a 5.5%
improvement with Pentium III Xeons. If you want to see those results:
PostgreSQL 7.4.1:http://khack.osdl.org/stp/285062/
PostgreSQL 7.4.1 w/ your patch:http://khack.osdl.org/stp/285087/
