I should have noted that the filesystem in use (in which the encfs directories exist) is btrfs. Problem no longer occurs on kernel-3.8.0-0.rc5.git1.2.fc19.x86_64, closing. |
Created attachment 689365 [details] I straced the encfs process for a few seconds Description of problem: When running with kernel-3.8.0-0.rc5.git0.1.fc19.x86_64 on F18 and using encfs, the encfs process consumes a CPU (~25% CPU on my core2 quad) while mostly idle. Version-Release number of selected component (if applicable): kernel-3.8.0-0.rc5.git0.1.fc19.x86_64 How reproducible: Steps to Reproduce: 1. Install kernel-3.8.0-0.rc5.git0.1.fc19.x86_64 2. Mount an encfs directory 3. Point some apps at the corresponding unencrypted directory 4. Have them occasionally manipulate some files Actual results: 100% of one core CPU utilization. Expected results: Near zero CPU utilization, as on kernel-3.7.4-204.fc18.x86_64 Additional info:
