FreeBSD machine: Pine64+ 2GB? Ryzen Threadripper 1950X? . . .? It would help to specify the type of system and its relevant properties (not just the processor). What independent channels are in use? Any? Or are the source and destination on the same channel at some stage? > I transferred about 30GB of audio from laptop The 30GB was on what type of device? Plugged in to what?

And in another message (indicating the other direction of transfer compared to the above?): > I use the phone, LG V30 to record basically ungraded RAW video files to the > microsd card; they are large files. > I transfer them to my computer copy a backup to the 1TB driver; then do > edits/ color grading, etc in blender, > then I transfer the finished to another 1TB hdd for backup as well. So the LG v30 was plugged in as a USB device, effectively acting as a media reader/writer? What file system? (It seems unlikely that the LG v30 would use a FreeBSD native file system to record RAW video files.) Going the other direction of providing some examples of files copies for UFS. . . Note: These are based on head -r327485 with non-debug kernel builds. Example performance copying /usr/src/ : (lots of small files on a fairly low-end FreeBSD machine) RPi2B V1.1 (with USB 2.0) One USB 3.0 powered hub (USB 2.0 compatible) with both: A) USB 3.0 SSD stick (USB 2.0 compatible) with the root file system B) 64 GB eMMC on a usdcard adapter, plugged into a USB 3.0 media reader/writer (USB 2.0 compatible). mount -o noatime in use for (A) and (B).

Having a few large files to copy instead should normally be faster in each of the earlier example contexts. But no hard drives or flash drives were involved: all SSDs of one form or another. Hard drive properties and file system fragmentation could make things much slower by comparison. Flash drives also can have issues. === Mark Millard markmi at dsl-only.netReceived on Sun Jan 07 2018 - 08:36:01 UTC
