https://bugs.winehq.org/show_bug.cgi?id=42104 Bug ID: 42104 Summary: EXT4 filesystem slows down WinRAR Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: k638540(a)mvrht.com Distribution: --- Hello. Instructions to reproduce the bug: 1) create any multivolume archive with WinRAR 5.40 (older versions are probably OK too), set volume/part size to 1GB or 2GB, full archive size 5-10GB, do not use compression, only store mode 2) in the end of creating each volume you'll see 3-5 seconds lag and info "calculating the checksum 99%", but all CPU cores are doing nothing at this moment 3) bug is not present on tmpfs (ramdisk), not present on NTFS (Windows 7 @ virtualbox) All tests were perfmormed on Ubuntu 14, 3GHz 8 cores CPU, normal HDD. I tried editing etc/fstab, I tried to add "noatime", but it didn't change anything. In practice, when you create 100GB archive splitted into 1GB parts, entire operation is finished 10 minutes later thanks to this 3-5 seconds delay for each part. I hope somebody can fix this. Thank you. PS. Wine version doesn't matter. I tested pretty much everything what's available (1.4 1.5 1.6 1.8 2.0 beta). -- Do not reply to this email, post in Bugzilla using the above URL to reply.
