Re: Extermly slow synchronization with my new flash drive


All my other sync's copy fine.
Does that mean that only with FFS's Mirror copy is where you are running into slowness?



Only with FFS's sync I have for this (new flash) drive.
I have two other syncs, one between an external HD and my local HD and one between two external drives. Both with ...

Re: Extermly slow synchronization with my new flash drive

tanin: Hey guys, these results seem weird, what's up?
Everyone: Run consistent tests and measure the performance that way
tanin: no xCSxXenon, 11 Apr 2023, 15:16
What is a consistent test?
I though that copying the same file through FFS and through Windows explorer, measuring times is enough of a test.

Re: Extermly slow synchronization with my new flash drive

There are.
Just tried syncing one 2gb file with FFS, it reached the 20% mark at about 4 minutes, so about 20m for a 2gb file.


Copying multiple small files are always much slower than copying 1 large file, even if they have the same total, due to various reasons:

Re: Extermly slow synchronization with my new flash drive



a 300mb file took about a minute.


Copying 103 files ~2gb took 9:46 minutes.


Copying a 2.5gb file from Windows Explorer took 2:05 minutes.


Three completely different datasets


The first two are estimates, afterwards I started using a stopwatch.

But there's still a pretty huge gap ...

Re: Extermly slow synchronization with my new flash drive

Your tests are useless.
Stop changing what data you are transferring and timing xCSxXenon, 04 Apr 2023, 14:28
What do you mean?
Copying the same file through FFS and Windows Explorer is not good comparison?

Re: Extermly slow synchronization with my new flash drive

I upgraded to 12.1 from 11.x since I thought this will solve my problem.
Copying a 2.5gb file from Windows Explorer took 2:05 minutes.

Re: Extermly slow synchronization with my new flash drive

Test some more, 'pretty sure' isn't meaningful unfortunately xCSxXenon, 02 Apr 2023, 14:03
100% sure. "Pretty sure" was just a manner of speaking.

Just checked again just in case, a 300mb file took about a minute. Copying 103 files, ~2gb took 9:46 minutes.

Re: Extermly slow synchronization with my new flash drive


FFS probably transfers that same 2GB file just as fast, but your initial picture is not showing 2GB files, it is showing 156 files around 84MB each. Are you sure FFS is slower when you are testing the exact same file(s)?


Pretty sure. When I took the screenshot I missed the part with the file ...

Re: Extermly slow synchronization with my new flash drive

Sounds like a cheap flash drive performing like a cheap flash drive. xCSxXenon, 30 Mar 2023, 16:17
I see.
But the drive performs enough for my needs (backup) under Windows Explorer. Copying a 2GB file directly doesn't take 2-3 minutes like it does when using FFS.

Re: Extermly slow synchronization with my new flash drive


Which?

PNY Attache 4 512GB USB 3.1 Flash Drive

USB 3 with a USB 3 port, you would expect more, just saying.

USB 3 port indeed, how much more? From what I saw online, 30MB + is expected.


Are they also to this same drive or elsewhere?

Other drives.

Note that copying directly to the drive ...

Re: Extermly slow synchronization with my new flash drive

The first copy was through Windows Explorer and is about 300gb. FFS is copying avout 13gb, so it does only includes the changes (which I also checked manually).
I also see that the copying is slow by looking at the file being copied. For example a 2gb file takes 2-3 minutes.

Extermly slow synchronization with my new flash drive

Hello,
I recently bought a usb 3.1 flash drive and created a new sync for it with FFS.
When I try to sync it is extremely, see picture.

The sync is of Mirror type, so before syncing for the first time I copied all the files in Windows Explorer and it went fine. I also tested the usb's write speed ...
