The speed and time numbers which each program displays may not be directly comparable as they may measure speed differently, and may show the time taken to buffer the data rather than flush it to disk (or at least through the network). Do it a few times using the same files in both programs, to account for caching etc. Assuming nothing else is using the network, start the copy, then time how long it takes before the network activity returns to normal. The most accurate way is to open Task Manager or Resource Monitor and display a graph of network activity. How are you comparing the network copy speeds? Is there anything else you can think of that I could try - before I wipe out DO12 and go back to 11 and try that again ? I should mention that I work in ICT, at the thick end of things - as a secondline analyst, I know that doesn't mean that I know anywhere near what you do regarding this short of thing, but I'm not a numpty either !! I'm at a loss as what is going on here !! I have created a temp share on the C:\ drive of my server which is an SSD with standard NTFS formatting, and am getting exactly the same speed, so it not an issue with REfs.
#Syncovery buffer size install#
I'm running on a relatively fresh (clean) install of Win10, all drivers are up-to-date, and as mentioned I have no issues with file moves outside of DO.
#Syncovery buffer size software#
I have turned my AV off (Kasperski) I don't run any software firewalls at all, I only use a hardware firewall on the external facing router.

5 (yes I did exit out of DO completely before retrying and also tried a full reboot.īut File Explorer \ Syncovery and Robocopy all copy to the same location and same file at ~110 MB/s I have tried your suggestions regarding buffer size and io_threshold and nothing makes any difference, it seems that any file transfer over my LAN is capped at 33 MB/s +/. On our side, nothing has really changed in this area so any sudden slowdown is probably an external factor, assuming you went from a recent Opus 11 to Opus 12. The same things can also treat different executable files differently, or treat different data being copied differently. Some of them (anti-virus/firewall software) auto-update and can become pathologically slow with certain operations.
Some of those things can be very sensitive to buffer sizes. But you would not see that as a change from going from Opus 11 to Opus 12 unless you moved from a very old version of Opus 11.Īside from those two settings, most of what affects copy speed in Opus is external: The physical hardware, the drivers, network, anti-virus, firewall, etc. You could try setting that to "1 MB" to get back to how the old default was. The copy_nonbufferio_threshold setting's default did change some months ago, to make things more compatible with some non-standard filesystems, and that could slow things down a bit in some cases. Preferences / Miscellaneous / Advanced: copy_nonbufferio_threshold Preferences / Miscellaneous / Advanced: copy_buffer_size The two settings within Opus which can affect copy speed are:
(We don't touch that code unless we really need to, since it is both critical it doesn't go wrong, and mature enough that we almost never have any reason to change it.) The way Opus reads/writes files when copying and moving has not changed at all from Opus 11 to Opus 12.
#Syncovery buffer size windows 10#
I'm running Windows 10 64bit on an extremely high spec PC. I really like the file copy API of DO, being able to queue multiple move operations and such like, but at this loss of speed this is going to be very painful when I start to do things like moving VM's aroundįor information - I have only very recently installed DO11 (after trialing it both on Win7 and then Win10) and have not "fiddled" with it very much other than changing the colour of the file and tree windows. Same file size with Explorer I am getting 108 MB/s taking 11 seconds.
#Syncovery buffer size upgrade#
Today is actually the first time since the upgrade that I needed to move some stuff over to my server, and thought to myself as I was doing it "hang on this doesn't normally take this long" so started to note down times and speeds.įor 1.2Gb file size with DO12 I am getting an average of 33.2 MB/s taking 38 seconds mkv video files from my download drive (Samsung 850Pro) to my storage server (Server 2012R2 - 6 disk storage pool - REFs) over a Gigabit LAN. Since upgrading to DO12 my file move speed has drastically reduced, it's slower than it was with DO11 and WAY slower than Windows Explorer which is a shock !
