I have to agree for the most part. My system used to use a lot of cache, and swapped all of the time with 300+MBs of ram on a Linus 2.4 kernel, now with -ac my swap is under 1kB with the same apps and load. I can even run ext3 now without another patch :).
One thing I have noticed is that I still see my system accessing the drive softly for about 30 second time periods a few times a day. I didn't see this on 2.2, and vmstat doesn't show any paging traffic, but it does show about 48 avg pages/sec going out to the disk. I haven't really looked very hard to find the culprit. Has anyone else noticed this?
[OT] Hmm, why isn't ext3 in the Linus kernel yet? It seems more mature than reiserfs was when it was included back in 2.4.1... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
