Hi all,
I've revived my Dual-CPU Pentium III/850: I couldn't notice a scalability-problem (two cpus are around 190%, but just the normal performance of 2.6.25-rc3 is abyssimal, 55 to 60% slower than 2.6.18.8:
psem 2.6.18 2.6.25 Diff [%] 1 cpu 948.005 398.435 -57,97 2 cpus 1.768.273 734.816 -58,44 Scalability [%] 193,26 192,21
pmsg 2.6.18 2.6.25 Diff [%] 1 cpu 821.582 356.904 -56,56 2 cpus 1.488.058 661.754 -55,53 Scalability [%] 190,56 192,71
Attached are the .config files and the individual results. Did I accidentially enable a scheduler debug option?
