I tested by loading 117 good sized images all at once. The point of my patch is to balance the VM and improve performance for not memory trashing proggy. It make sense that the trashing program is been slowed down... Once the proggy will stop allocating RAM but it will continue to use only pages just allocated (eventually in swap) performance should return normal. > patch (still running under the patched 2.2.0-pre1) and noted that during > the compile I had 17MB in the swap with nothing else going on. Bringing > up netscape put it up to 25MB. Suggestions? Requests? Let me know if I am going to still change something for sure. But please don't care the size of the SWAP, care only performances. The pages in the swap right now are likely to be present also in the swap cache so you' ll handle both aging and a little cost in a swapin using more the swap cache. Really there's also the cost of an async swapout to disk but it seems to not harm here. > you want me to try anything else. Yes you should tell me if the performances decreased with normal usage (like netscape + kernel compile). Andrea Arcangeli -- This is a majordomo managed list.
