# The 2.6.25.9 stable kernel update is available. # This one contains a relatively small set of patches; # one of them might be security-related, and another # addresses a serious virtual memory performance regression The problem is explained in a previous version of the patch: http://lwn.net/Articles/287342/ # In particular, the removal of ZERO_PAGE effectively # removed the core file writing optimization where we # would skip writing pages that had not been populated # at all, and increased memory pressure a lot by allocating # all those useless newly zeroed pages. -- Christopher Samuel - (03) 9925 4751 - Systems Manager The Victorian Partnership for Advanced Computing P.O.
