If I were to guess.... Does the slow volume have a large number of files?
You betcha. :-)
Are those files tiny?
Some yes, some no.
Do a df -i to see how many inodes are in use.
We seem to be around 60% on average.
Have you ever increased maxfiles?
No.
Have in ever increased the volume option for max-dir-szie?
Yes. Values are consistently set at 20971 on source and destination volumes on *all* filers.
Either of those two changes will adversely affect the speed of *any* file-based backup.
Even so, when I consider that the other node had the same settings and didn't exhibit this slowness, I am left confused. :-(
