I observed that performance of some memory hog benchmark does not stable, depending on the pagecache size. I think it is natural behavior of VM subsystem, but some user care for perfomance stability :-< I saw /proc/sys/vm/pagecaches sysctl entry in early 2.4, but "max_percent" value was not used in the source code. On newer kernel, entry itself seems disappeared... Is there any trial to provide feature to limit pagecache?
