On the -rc2 machine, however, I don't feel anything is sluggish yet. But I think if I leave it running long enough it might run out of memory.
I don't know if this is perfectly normal given the differences between 2.4.x and 2.6.x VM. I will keep it running and under load for a while and report any interesting stuff.
Here is /proc/meminfo on the rc2 box as of now - [EMAIL PROTECTED] paragw]# cat /proc/meminfo MemTotal: 775012 kB MemFree: 55260 kB Buffers: 72732 kB Cached: 371956 kB SwapCached: 40 kB Active: 489508 kB Inactive: 182360 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 775012 kB LowFree: 55260 kB SwapTotal: 787176 kB SwapFree: 787136 kB Dirty: 2936 kB Writeback: 0 kB Mapped: 259024 kB Slab: 32288 kB CommitLimit: 1174680 kB Committed_AS: 450692 kB PageTables: 3072 kB VmallocTotal: 253876 kB VmallocUsed: 25996 kB VmallocChunk: 226736 kB HugePages_Total: 0 HugePages_Free: 0 Hugepagesize: 4096 kB

OK. There's rather a lot of anonymous memory there - 700M on the LRU, 300M pageache, 400M anon, 200M of slab. You need some swapspace ;)
What are the symptoms? Slow to load applications? Lots of paging? Poor I/O speeds? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
