op-ssh-sign is very slow

I have noticed the same thing on Arch Linux. This has started a few months ago, sorry I don't have the precise version.

When I run op-ssh-sign through strace when it gets invoked by git, I see that it blocks for ~1 second on a recvfrom syscall on the ~/.1password/agent.sock socket (which is the socket set in my SSH IdentityAgent) to read what looks like the key retrieved from 1Password.

So I assume the problem isn't with op-ssh-sign itself (not surprising) but with the main 1Password client taking a while to send back that key...

It feels like it has been getting slower and slower in the past few months! Man it's painful to commit or push right now... I really like having my keys in 1Password, but I'm starting to be tempted to add them back onto my machine directly just for the speed benefit...

It just took me 12.532 seconds to push a one-line change to GitHub... :.....(

Same here. I might add I use WSL (Windows Subsystem for Linux) to use the named pipes to forward my windows' 1Password ssh-agent to also work in Linux. This has worked flawlessly for way over a year now but since around April I experience the same problem. Up to around 10 seconds per ssh agent request. It's reproducible and takes the same high amount of time every single time. I had to switch back to a classic key-agent until this is fixed. Very annoying.
