Slow Comparison

Posts: 1 · urbanspike 3 Aug 2022, 08:18

Hello,

We are french users.

We updated the software last April (v11.20). Since the comparison between our 2 directories (about 1TB) is really much slower. Before, it took a few hours (about 3 hours) now we are more around 18 hours.
We haven't changed the method (date and size) or anything else. Any idea where this could come from?
We update today in 11.23 version.

Many thank's

Revert to old version and test. If it is still slow, then it's not a FFS issue

Not sure if this is related, but I have some issues with the 11.23 Version, the synchronising is very slow, about 20-30 MB, and will take about a day. That seems very slow. It starts out fast with 180 MB,then drops to 30 MB.

Sounds like a cache filling up and then slowing down to the real speed of the drive.

Is there a way to speed that up? Seems abnormally slow. I know that backing up large quantities of data (in my case about 4+TB) takes a while, but that long?

Mechanical drives suffer horribly from a large number of small files. You are getting exactly the speeds that are expected
