I have to say that the vm-patch against t8p5 works fine here on t8p6 I've tested to copy a few big files between partitions and it didn't swap at all (it used to swap like crazy leaving me to watch my frozen X during the copy) so far so good.... then a friend started a ftp-session against my machine and started to copy a few files (3-6MB each via 100Mbit network) and my machine began swapping like there was no tomorrow. after about 15-30 seconds of heavy swapping the swapping stopped, now I had about 35MB swapped out (I have 256MB ram, and the box is very light loaded, no big memoryhogs or anything (not even netscape :)) I took a look at /proc/meminfo and I had more than 200MB in active pages and almost nothing in inactive pages. So this is a case where drop-behind doesn't work yet. I should say that my ftpserver is proftpd-1.2.0pre10, a quite common ftpserver /Martin -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
