And beta 4 was the fast one in your setup! Does this mean Beta 7 is as fast as Finder on your system?

To not lose track:
beta3: Disable caching source & target + F_RDAHEAD beta4: Disable caching only for the target beta5: Disable caching source & target + less mem copies beta6: Disable caching source & target + larger buffers beta7: Disable caching source & target + larger buffers + prefetching thread

Yes, Beta 7 was as fast as Finder. Not tested in depth... I will try this week.

We tested Beta 7. Speed is mostly at 450MB witht up to 750MB (with the finder/testtool we reach 950MB via smb). We just copied 271GB to the server without crash.

Occasionally ffs is hanging with 0MB for around 3-5 seconds and then ffs goes on with good speed.
So it is much better because we have no crashes and faster speed.

Our System is an 10GB Ethernet M1 Studio Ultra with 64GB Ram copying to a synology server via SMB with write speed up to 950MB.

So big thanks for the test and betas.

Is there anything we can help to test? Then we need a little manual or to do-list, what we should test.
But thanks for this great tool and the betatesters here. You save us a lot of time!!

All in all this looks promising, so let's got with the "Disable caching source & target + larger buffers + prefetching thread" approach.

Here's the release candidate for FFS 11.26 including the latest changes: https://www.mediafire.com/file/d2zosp14j8f3ftg/FreeFileSync_11.26_RC_macOS.zip

Thank you Zenju for all the betas!

I have tried all the betas and the latest 11.26. They all crash my Mac Studio when writing to my QNAP NAS. It is set up in RAID 0 for speed. File transfers quickly get slower and slower, from over 400 Mb/s to less than 100, and eventually the Mac hangs.

...so any more update on this issue?

Which O.S?
I solved last year forcing Samba 2 between computers (Mac minis M1). Just an idea.

Mac Studio (as I said in my post) as shipped and with the latest updates applied. Solved in 2021? Really? So why does this thread even exist?

Using the sync function of the Forklift app, there are no issues whatsoever.

Not exactly solved, just protocol was changed to Samba 2 in several machines.
