Category: kernel modules Group: None Status: Open >Resolution: Fixed Priority: 7 Private: No Submitted By: David Koudela (dkoudela) Assigned to: Nobody/Anonymous (nobody) Summary: Slower vmhgfs when upgraded from 7.3 to 9.0.1 Initial Comment: Host OS: Windows 7 VM OS: Fedora 13 VM framework: VWare Workstation 7.3 and 9.0.1 After upgrade our VM workstation from 7.3 to 9.0.1, we realized that shared storage fs (vmhgfs) is dramatically slower than in previous version. After an exploration, we found out that it is caused by new version VMtools. Example: File copy on a system with VMtools from VMware Workstation 7.3 $ dd bs=1024 count=102400 if=/dev/zero of=/mnt/hgfs/webdev/randfile.bin; time cp /mnt/hgfs/webdev/randfile.bin /mnt/hgfs/webdev/randfile.bin.tmp; rm -f /mnt/hgfs/webdev/randfile.bin.tmp 102400+0 records in 102400+0 records out 104857600 bytes (105 MB) copied, 2.25995 s, 46.4 MB/s real 0m2.789s user 0m0.001s sys 0m2.785s After VMtools upgrade (VMware 9.0.1): $ dd bs=1024 count=102400 if=/dev/zero of=/mnt/hgfs/webdev/randfile.bin; time cp /mnt/hgfs/webdev/randfile.bin /mnt/hgfs/webdev/randfile.bin.tmp; rm -f /mnt/hgfs/webdev/randfile.bin.tmp 102400+0 records in 102400+0 records out 104857600 bytes (105 MB) copied, 24.2573 s, 4.3 MB/s real 0m4.428s user 0m0.000s sys 0m4.425s The duration is 1.5x longer than before. In case of multiple files and several kinds of operations, it is even worse. Compilation of our product takes 5min on VMtools 7.3 but it requires 25min on VMtools 9.0.3 This means it is 5x slower. Could you please fix this performance issue? Thanks. ---------------------------------------------------------------------- >Comment By: Dmitry Torokhov (dtor) Date: 2013-04-24 09:13 Message: This should be fixed in the newer releases (9.2.3 and 2013.04.16). ---------------------------------------------------------------------- Comment By: Steve (lousybrit) Date: 2013-02-01 09:59 Message: Thanks so much for reporting this issue together with the tests you have run. This is a known issue and has a bug filed against the HGFS file sharing. I am going to be looking into this very shortly. Thank you.
