I got the patch and I must say I'm impressed. I ran my "117 image" test and got these results: [Note: This loads 117 different images at the same time using 117 separate instances of 'xv' started in the background and results in ~ 165 MB of swap area usage. The machine is an AMD K6-2 300 with 128MB] 2.1.131-ac11 172 sec (This was previously the best) 2.2.0-pre1 + Arcangeli's 1st patch 400 sec test1-pre + Arcangeli's 2nd patch 119 sec (!) Processor utilization was substantially greater with the new patch compared to either of the others. Before it starts using swap, memory is being consumed at ~ 4MB/sec. After it starts to swap out, it streams out at ~ 2MB/sec. The performance is ~ 45% better than ac11 and ~ 70% better than 2.2.0-pre1 in this test. I was going to test the low memory case but got side tracked. Thanks, Steve -- This is a majordomo managed list.
