I'm not aware of any benchmarks but empirically, using compressed swap has reduced the networked swapping while e.g. browsing (seems like pixmaps make good part of 4x+ compression). > Or in other words, what observation motivated you to include > compcache? :) Didn't ask about *inclusion* but can say that *leaving it* wasn't even discussed, the effect is quite nice. In ALTSP5, compcache gets enabled if there's something like 20M RAM free or so, basically it gets enabled on 64M+. > BTW, I am interested in that enhancement patch, where can I > find it ? Here (sorry for taking so long, things are a bit busy here): http://ftp.linux.kiev.ua/pub/Linux/ALT/people/led/patches/compcache-0.3-proc.patch.gz led@ mentioned that he'd better make counters for average compression ratio but didn't get around so only did a second "histogram bar". :) -- ---- WBR, Michael Shigorin <mike-u2l5PoMzF/[email protected]> ------ Linux.Kiev http://www.linux.kiev.ua/ ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
