There is a significant performance regression in trunk in deleting files from within the IDE after the new BuildSys was integrated. Here are results from testing on W2K (Dell Precision 220, PIII 800MHz, 512MB RAM, Windows 2000) and Linux (Dell Latitude C840, PIV 2.2GHz, 1024MB RAM, Red Hat 9). Each test was repeated three times. 1) Delete a folder w/ 1000 simple java files W2K: 200403141900 - 9516ms, 8062ms, 8922ms 200403191248 - 16125ms, 16188ms, 17875ms Linux: 200403141900 - 3697ms, 3479ms, 3199ms 200403191248 - 4305ms, 4647ms, 4352ms 2) Delete a folder w/ 1000 simple text files W2K: 200403141900 - 6906ms, 6703ms, 6797ms 200403191248 - 12375ms, 12219ms, 12203ms Linux: 200403141900 - 2473ms, 3349ms, 2440ms 200403191248 - 4198ms, 3411ms, 3337ms
Tomasi, I've done measurements with today's trunk and deleting folder with 1000 javas is even worse than before. And on W2K it takes ridiculously long. The numbers below are measured with my build 200405271200. 1) Delete a folder w/ 1000 simple java files W2K: 188s, 187s Linux: 15747ms, 17484ms, 18180ms 2) Delete a folder w/ 1000 simple text files W2K: 187s, 186s Linux: 14688ms, 15397ms, 17057ms I will look into the W2K case in profiler.
Tomasi, I've found what is the problem with the very long times on Windows. You can see details in issue 44003.
Closing as duplicate of issue 43278 because as refactoring is in trunk now we don't need to have two bugs covering one functionality. Tomasi, add your comments to 43278. Thanks. *** This issue has been marked as a duplicate of 43278 ***
