January 3, 20197 yr Hello, I'm running unRAID v6.6.6 on a HP Compaq 6000 Pro Microtower. I've installed "Community Applications" Plugin and Zoneminder Docker. I appear to be experiencing a performance issue that I don't know how to debug. Any help would be much appreciated. You can see below, I've issued a rsync command to copy from 192.168.0.232 to unRAID and the file transfer speed has slowed to a crawl. I verified that the 192.168.0.232 server is performing well. root@Tower:/# rsync --progress -rltuv [email protected]:/mnt/Vol1/ /mnt/user/unRAID/ [email protected]'s password: receiving incremental file list ./ .windows 0 100% 0.00kB/s 0:00:00 (xfr#1, ir-chk=7016/7018) Backups/ Backups/.DS_Store 8,196 100% 7.82MB/s 0:00:00 (xfr#2, ir-chk=7011/7018) Backups/._.DS_Store 4,096 100% 3.91MB/s 0:00:00 (xfr#3, ir-chk=7010/7018) Backups/Amy (Mac Mini)/ Backups/Amy (Mac Mini)/.DS_Store 6,148 100% 5.86MB/s 0:00:00 (xfr#4, ir-chk=6991/7018) Backups/Amy (Mac Mini)/._.DS_Store 4,096 100% 1.95MB/s 0:00:00 (xfr#5, ir-chk=6990/7018) Backups/Amy (Mac Mini)/._Macintosh HD.dmg 4,096 100% 1.30MB/s 0:00:00 (xfr#6, ir-chk=6989/7018) Backups/Amy (Mac Mini)/Macintosh HD.dmg 20,678,180,864 62% 19.85kB/s 176:00:06 20,760,494,080 62% 19.85kB/s 174:50:47 20,763,115,520 62% 7.44kB/s 466:37:33 20,763,377,664 62% 0.62kB/s 5578:17:22 tower-diagnostics-20190102-2235.zip
January 3, 20197 yr Community Expert There was a xfs related call trace, reboot, check filesystem on disk1 and try again.
January 4, 20197 yr Author Thank you for the guidance. I wasn't able to reboot or shutdown via the GUI so I had to powerdown from the CLI. Disk 1 filesystem check output is attached. I then tried the rsync again with similar results: Backups/Amy (Mac Mini)/Macintosh HD.dmg 12,365,856,768 37% 19.85kB/s 292:19:07 12,387,876,864 37% 19.85kB/s 292:00:17 12,395,216,896 37% 19.85kB/s 291:53:47 Disk1_Filesystem_Check.txt tower-diagnostics-20190104-1244.zip
January 4, 20197 yr Author Looks like I have a bad stick of RAM. Will try the rsync again and report back.
January 9, 20197 yr Author Removing the bad RAM fixed the issue. That said, rsync is topping out at approx. 21 MB/s. When I manually copy (SMB) a large file from the same source host to a different destination host, my laptop, I get 120 MB/s. All three systems are connected to the same switch. SMB get from the same source to unRAID averages approx. 65-70 MB/s Why is rsync three times as slow as SMB with the same source and destination and almost six times slower than SMB from the same source to a different destination on the same switch? Thx

January 10, 20197 yr Community Expert That should be fine, just checking you weren't using the compression flag, using a different cipher can give a little more performance with rsync but that doesn't explain 20MB/s, so something else is going on, assuming the CPUs in use are powerful enough, i.e., they are not a couple of single core Atom CPUs.
