However, I took a look at the relevant code in 2.4.22pre7aa1 and I believe my patch should help there as well. The writepage() and page rotation behaviour is similar to stock 2.4.22 though the inactive_list is per-classzone in -aa. I am less sure about the inode/dcache part though under -aa. --- Mike Fedyk wrote: > On Fri, Aug 29, 2003 at 10:55:44AM -0700, Shantanu > Goel wrote: > > I am not very knowledgeable about > micro-optimizations. > > I'll take your word for it. ;-) What interests > me > > more is whether others notice any performance > > improvement under swapout with this patch given > that > > is on the order of milliseconds. > > But have you compared your patch with the VM patches > in -aa?
