I disabled the L2 cache to see if that would make any differences: the

With kernels 2.1.x SMP on PPro and PII, when the system is altered
(after an heavy load on the system), everything slows down.

Did you try Solaris 2.6 on your K6 system ?

Does Sun offers trials version of Solaris for Intel CPU ?
