In trying to apply Jens's patch I upgraded to 2.4.2-pre1. The figures on it(242-p1) look better at this point: a vmstat dump, same data...notice this time it only took maybe 45 seconds to write out the data. I also got better interactive performance. So write speed is up to about 3.5Mb/s. Fastest reads using 'hdparm' are in the 12-14Mb/s range. Sooo...IDE hdparm block dev read vs. file writes...3-4:1 ratio? I honestly have little clue as to what would be considered 'good' numbers. Note the maximum 'system freeze' seems under 10 seconds now -- alot more tolerable. Note also, this was without my applying Jens's patch -- as I could not figure out how to get it to apply cleanly :-(. 0 0 0 0 77564 80220 280164 0 0 0 348 287 1367 10 7 83 0 0 1 0 77560 80220 280164 0 0 0 304 193 225 0 1 99 0 1 1 0 77572 80220 280156 0 0 0 162 241 354 4 2 95 0 1 1 0 77572 80220 280156 0 0 0 156 218 182 0 1 99 1 1 1 0 77560 80220 280164 0 0 0 165 217 218 0 1 99 0 1 1 0 77328 80220 280164 0 0 0 134 213 215 1 1 97 0 1 1 0 77328 80220 280164 0 0 0 138 217 177 0 1 98 0 1 1 0 77328 80220 280164 0 0 0 206 215 178 0 1 99 0 1 1 0 77332 80220 280164 0 0 0 166 219 206 1 1 98 0 0 0 0 85632 80220 280172 0 0 14 12 192 360 1 1 98 -- Linda A Walsh | Trust Technology, Core Linux, SGI [EMAIL PROTECTED] | Voice: (650) 933-5338 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
