Hi all, I've run a 'let's check if it does not skip frames test'. kernel is 2.5.62-mm2.
** How I performed the test ** startx I've opened to xterminal
terminal1 [test@frodo test]$ glxgears
terminal2 ./dbench 16
Following the results:
** booted with scheduler=as ** Throughput 19.8092 MB/sec (NB=24.7615 MB/sec 198.092 MBit/sec) 16 procs

I can not see any difference in the results above.
I guess the test I've run it is not a good test, isn't it ?
Comments/suggesiontions ?
Ciao, Paolo
