Any more thoughts on how I might fix this? My SSD has a write speed of 1500Mb/s, so any buffer flushes ought to be near instantaneous

I wonder if the plateau you are seeing is a buffer being filled up, then 0 while it empties it to disk xCSxXenon, 02 Mar 2021, 20:27

That does sound right. Any tips on what I could do about it? It’s clearly fine at the OS level, and I can’t find a FFS buffer setting

I'm accessing my work server over an SMB share, via Pulse Secure VPN on Mac OSX 10.14.6 with a 200Mbps downlink. Just dragging a file in Finder, I get about 5MB/s. Using FFS on my Windows PC is about the same. But using FFS on the Mac, it drops to 2.5MB/s at best, and more usually 1.5MB/s I've tried...

I'm not sure how that would help. If I had the large file copy as a separate config, with a low thread count, I'd still then have to do the very slow comparison. My current workaround is simply to scan with 10 threads, then lower the thread count if there are large files to sync. Ideally, I'd want s...

I'm accessing an SMB share over a VPN, so there's a lot of lag and latency. When comparing large folders, this means the more threads the better - I've found performance peaks at about 10 threads. However, if there's then a lot of large files to sync, trying to copy 10 at once seems to choke the con...

I'm using Mirror to back up some of my Dropbox folders. There are often large files moved or renamed, so I want the "Detect moved files" option, which needs the database. Telling Dropbox to ignore it once the FFS is complete rather defeats the object, since Dropbox will have been continuou...

I have a similar issue. A good solution would be for FFS to set the com.dropbox.ignored attribute for its database and lock files. This can be set manually, but seems to get lost every time FFS updates the files

I had thought of that, but my daily backup is multiple pairs already, so doubling that up would be a pain to maintain

I love the versioning feature of FFS. Between it and date macros, I have a really elegant backup solution. The only extra thing I'd like is disk space based versioning. If I have a small text file, I'm happy to keep lots of versions of it, but a multi-gigabyte, maybe only 3. Could there be another o...
