Make sure that you have dir_index turned on in ext3. Type tune2fs -l /dev/?da? | grep features
For example, if /home is /dev/sda5 on your system type tune2fs -l /dev/sda5 | grep features If this feature is not turned on, small file performance on ext3 is dirt slow . . . However turning it on does not speed up directories that already exist. You will basically have to do a backup/restore. Thanks, Erik On 6/5/07, Alexandre Shima <[EMAIL PROTECTED]> wrote:
Hello Helmut, I'm running QmailToaster on a HP DL380 G3 Server (Dual Xeon 3.0, 2 GB RAM, 6x 73 GB SCSI 10K RAID 5, 64 MB w/battery) with RHEL4 ES (I had the same servers configured with RAID 10 - same problem). The filesystem is EXT3. I'm trying to backup with HP Dataprotector 6. I'm trying to keep another system (stand by server with same configuration, connected to a gigabit LAN) updated with RSYNC. The big problem is that it takes too much time to copy/sync the Maildir. RSYNC takes about 8 hours just building the file list. I have tried to copy data with scp, and I had the same poor performance. I have read a lot about problems with EXT3. It looks like it does not have a good performance with large structures like my Maildir directory, and that ReiserFS or XFS will do better in this case. I'm also considering to move everything to a storage, with the GFS filesystem. At least I think I'll be able to load balance these servers easily. Thank you. Alexandre
