This is on a 8-core Nehalem with 8GB of memory, and a fast PCI-e flash device. One thing I noticed is that your config seems to run many fs tasks a lot slower than mine, but I'm not entirely sure why. The only interesting things I noticed in your config where that you use slub instead of slab, which does a lot of high order allocations and has caused lots of trouble in the past, and that you enable CONFIG_CC_OPTIMIZE_FOR_SIZE, which has caused mis-compilation of complicated code in the past. I don't want to blame it directly, but I could see how that causes problems with some of the atomic64_t games XFS plays since 2.6.38. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
