sshfs extremely slow file transfers

[jeffreydlong]

Hi, I'm using:
SSHFS version 2.5 (OSXFUSE SSHFS 2.5.0)
OSXFUSE 3.8.3
FUSE library version: 2.9.7

on 10.13.6. File transfers when using cp over sshfs mounts are much slower than just using scp to copy the same file between the local and remote system. I suspect this problem is related to libfuse/sshfs#11

Same with me... it is like 10 times slower and thus unusable
scp 11,6 MB/s
sshfs 1,7 MB/s

same problem here, but 20x slower: 1.5 MB/s vs 24 MB/s.

You can use Homebrew to update to a patched sshfs version 2.10 that fixed this issue for me when using the -o iosize=1048576 flag.

Same here...
Already downloaded file copy: up to 45 mb/s
Internet download being saved over sshfs: 0.3-1 mb/s

Downloading from google server, so normally speed is maxed out. Seems like sshfs is struggling with lots of small data chunks being transfered.

Homebrew and osxfuse/sshfs ended up parting ways, so Mac Ports is probably the better option now.
