Here are the results of comparison of kernel 2.5.53-mm2 and 2.5.53-mm1. on TIObench. key findings are listed in the table. Values in the table indicate approximate percentage change with respect to previous result. Please see the mail in full window to see the formatted results. ------------------------------------------------------------- test 2.5.53 with mm2 (as compared to 2.5.53-mm1) APPRXIMATE % change ------------------------------------------------------------- rate (megabytes per second) 7to 8% decrease CPU % utilization apprx 10 % decrease Average Latency 15% increase Maximum latency 10% increase CPU efficiency 10% decrease -------------------------------------------------------------Here are the complete results. *************************************************************** TIObench kernel 2.5.53-mm2 *************************************************************** No size specified, using 252 MBUnit information ================ File size = megabytes Blk Size = bytes Rate = megabytes per second CPU% = percentage of CPU used during the test Latency = milliseconds Lat% = percent of requests that took longer than X seconds CPU Eff = Rate divided by CPU% - throughput per cpu loadSequential Reads File Blk Num Avg Maximum Lat% Lat% CPU Identifier Size Size Thr Rate (CPU%) Latency Latency >2s >10s Eff ---------------------------- ------ ----- --- ------ ------ --------- ----------- -------- -------- ----- 2.5.53 252 4096 10 8.27 6.104% 13.685 1395.01 0.00000 0.00000 136Random Reads File Blk Num Avg Maximum Lat% Lat% CPU Identifier Size Size Thr Rate (CPU%) Latency Latency >2s >10s Eff ---------------------------- ------ ----- --- ------ ------ --------- ----------- -------- -------- ----- 2.5.53 252 4096 10 0.42 0.773% 260.404 1529.97 0.00000 0.00000 54Sequential Writes File Blk Num Avg Maximum Lat% Lat% CPU Identifier Size Size Thr Rate (CPU%) Latency Latency >2s >10s Eff ---------------------------- ------ ----- --- ------ ------ --------- ----------- -------- -------- ----- 2.5.53 252 4096 10 16.58 32.85% 4.373 17555.17 0.05469 0.00000 50Random Writes File Blk Num Avg Maximum Lat% Lat% CPU Identifier Size Size Thr Rate (CPU%) Latency Latency >2s >10s Eff ---------------------------- ------ ----- --- ------ ------ --------- ----------- -------- -------- ----- 2.5.53 252 4096 10 0.76 1.148% 2.491 1969.71 0.00000 0.00000 66 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
