ICH7 IO Performance Issues
Hi list, I recently bought a New Asus W5F - 12" Laptop and am experiencing some issues with: If "Heavy" disk access occurs I experience overall system hangs Say I just compiled OpenOffice.Org and am happy all is fine so I can do a make clean. Make clean generates quite a lot of disk IO and everything begins lagging like: ls or playing an MP3 file. So I tried to reproduce this by doing the following: cat /dev/random > /tmp/junk_file didn't have the same effect, but I think that's because the source was not the local disk but fast memory a cp of a big file (1GB) didn't do anything BUT an rsync of that very same big file did give me hangs in my music at least so I catted big file attached it to now even bigger file and had some trouble too. The more I spawned IO Processes the badder it got. Is that a known issue? With 1.5Gb Ram there is for sure no way I ran out of Ram or any other memory issue (3Gig Swap) Also whilst rsyncing locally from disc to disc I noticed only between 10MB/s - 15MB/s throughput on average it did spike on 24MB during a few seconds. I seem to notice this issue quite often on FreeBSD, I had major RAID performance problems with a Rocket Raid adapter (ok I know it ain't the best but for what it's worth it should be more or less stable) Are there disk I/O issues on a larger scale maybe?

Also, run 'vmstat 1' during that time and report what it says. I ran gstat and my ad4 is constantly on >90% whereas my da0 will stay in the 20% region... But I think thats normal. So see attached my different log files, they seem to be normal. the vmstat is difficult to read but I attached it anyways... cheers a lot., Steve procs memory pagedisks faults cpu r b w avmfre flt re pi po fr sr ad4 da0 in sy cs us sy id 3 9 0 26853364 61640 1446 579 28 9 2005 817 0 0 4515 8177 9357 9 12 80 3 7 0 26639956 57016 371 214 63 0 1738 0 159 27 12351 22366 23248 9 24 67 2 9 0 26136540 53360 463 211 50 11 1357 0 120 18 12027 18762 22189 9 26 64 0 9 0 26136540 47992 366 187 74 11 1966 0 179 37 14183 19214 26051 6 31 62 2 12 0 26853372 61564 409 169 45 21 1734 4303 127 20 11012 16167 20698 3 22 75 0 10 0 26864184 76428 2280 188 53 11 3199 6963 85 38 13191 20268 24876 7 26 68 0 9 0 26862104 73480 4825 136 60 46 4990 0 96 24 12171 22961 23317 7 29 63 1 11 0 26863736 68528 2093 51 12 120 2552 0 132 19 9125 19959 17975 9 30 61 2 9 1 26865440 64084 2402 79 29 48 3062 0 96 23 11435 17831 22453 3 27 70 0 15 1 26147392 63252 361 10 9 45 673 0 125 8 6032 9671 12478 6 19 75 0 10 0 26147348 58532 951 56 16 0 1989 0 150 42 10876 17083 21738 3 25 72 0 10 0 26864456 53620 753 135 47 2 1851 0 75 28 11401 16168 22302 5 22 73 3 8 0 26147348 81372 2471 109 40 33 3349 8971 99 27 12118 19019 23554 7 31 62 1 7 0 26143472 77804 5942 165 67 6 6491 0 81 27 13570 23371 25875 13 29 59 1 12 0 26171160 73508 1866 122 50 0 2480 0 69 19 11492 15790 21810 8 24 68 0 15 0 26173672 69144 803 173 57 0 1702 0 70 21 10694 12257 19917 9 24 67 0 14 0 26162372 65920 2064 148 63 0 2696 0 74 18 10418 12568 19407 6 24 71 4 10 0 26134804 61280 8481 184 61 0 8364 0 73 23 12040 21977 22550 11 36 53 procs memory pagedisks faults cpu r b w avmfre flt re pi po fr sr ad4 da0 in sy cs us sy id 0 6 0 26135096 57388 1919 283 67 0 2759 0 73 25 12689 14820 22858 4 29 67 1 8 1 26498192 54768 328 173 63 0 1223 0 125 14 9423 13784 17837 5 18 77 0 8 0 26851928 51332 627 183 68 0 1505 0 69 16 11421 15236 21066 6 21 73 0 6 0 26851928 47704 404 183 70 0 1465 0 72 22 11966 13796 22084 6 28 67 0 8 0 26851928 80644 466 182 58 32 1488 10135 96 22 10737 11808 19821 4 20 76 3 8 0 26797988 75716 447 195 61 0 1775 0 77 27 13031 17409 24260 4 27 69 0 11 0 26135096 71424 514 175 57 14 1627 0 75 25 12888 16612 24002 6 23 71 1 10 0 26136320 65780 383 226 64 0 1468 0 63 24 11866 14304 21896 7 20 73 1 10 0 26135096 63060 2771 162 74 0 3059 0 75 23 10956 16078 22404 7 26 66 0 12 0 26851804 58464 2147 139 65 0 2999 0 73 17 10348 16422 21333 13 25 62 2 10 0 26638388 49192 2675 87 37 0 4108 0 71 23 11167 18903 22470 16 29 54 4 12 0 26851148 85324 12737 200 65 32 11563 13510 104 14 9074 22969 19560 26 35 40 0 9 1 26132788 83568 6916 93 30 0 5591 0 110 7 6765 12519 13891 9 20 70 0 12 0 26801224 82104 2916 92 30 0 2987 0 99 25 6844 12738 14173 3 19 78 0 13 0 26138896 77168 807 162 77 0 1763 0 78 21 10832 14577 20775 5 25 69 0 11 0 26502756 73120 479 197 81 0 1457 0 81 17 10968 12807 20546 10 23 67 2 11 0 26139748 70276 614 155 84 0 1345 0 92 12 9589 10935 17978 7 22 71 1 11 0 26139748 68040 241 139 59 16 899 0 87 13 8466 9637 16017 4 17 79 procs memory pagedisks faults cpu r b w avmfre flt re pi po fr sr ad4 da0 in sy cs us sy id 1 10 0 26497144 66128 631 178 76 0 1434 0 79 21 10028 14165 19009 8 19 72 0 131 0 26851172 62388 314 183 66 0 1294 0 84 20 9984 11929 19064 8 22 70 0 10 2 26802600 58112 5976 173 57 0 6458 0 72 26 8740 14105 16939 15 24 61 2 12 0 26502956 54872 321 140 38 66 1071 0 89 15 9092 10350 17308 4 25 71 0 11 0 26504468 51896 413 42 11 110 1015 0 129 14 7280 9514 14273 4 21 75 2 11 0 26141648 81660 348 74 19 72 971 9458 113 14 7062 9504 14072 2 18 80 0 11 0 26141288 79084 399 61 23 83 958 0 106 9 6886 8107 13348 6 19 75 1 14 0 26141316 77600 30 36 6 1 432 0 140 10
