Hi, I've just started some tests to try to repeat the memory allocation errors. I see the aa1 kernel is twice fast as -pre12!? Is this expected? I have 2x intelPIII 933MHz, 1GB RAM, HIGMEM kernel, ReiserFS, aic7xxx, eepro100.
linux-2.4.10-pre12 dbench 16: Throughput 67.8566 MB/sec (NB=84.8208 MB/sec 678.566 MBit/sec) 16 procs
Yesterday after havy tests and after memory alloc. errors already appeared: total: used: free: shared: buffers: cached: Mem: 1054490624 880287744 174202880 0 4653056 460627968 Swap: 2147467264 42909696 2104557568 MemTotal: 1029776 kB MemFree: 170120 kB MemShared: 0 kB Buffers: 4544 kB Cached: 448416 kB SwapCached: 1416 kB Active: 377868 kB Inactive: 76508 kB HighTotal: 131072 kB HighFree: 2044 kB LowTotal: 898704 kB LowFree: 168076 kB SwapTotal: 2097136 kB SwapFree: 2055232 kB

Now after fresh bootup and just after I started first tests: total: used: free: shared: buffers: cached: Mem: 1054412800 110338048 944074752 0 8560640 59211776 Swap: 2147467264 0 2147467264 MemTotal: 1029700 kB MemFree: 921948 kB MemShared: 0 kB Buffers: 8360 kB Cached: 57824 kB SwapCached: 0 kB Active: 0 kB Inactive: 66184 kB HighTotal: 131072 kB HighFree: 58612 kB LowTotal: 898628 kB LowFree: 863336 kB SwapTotal: 2097136 kB SwapFree: 2097136 kB
The documentation to dbech is a bit sparse (README,INSTALL). It's a bit offtopic, but would someone explain me where does the dbench write, into which directory? I performed the tests above under same user and in same tmp/ directory, to be sure. Maybe it was not necessary at all. ;)
