Hi everyone!
I’m running into an odd issue right now; running lxc ls takes upwards of 30 seconds to execute on our LXD cluster. This is interfering with a JupyterHub instance (which spawns LXD containers) of ours which times out and fails when this happens, so I’d love to get it fixed, but I’m a loss as to what the problem is.
Interestingly, lxc ls --fast doesn’t have this problem, and I’ve tracked the issue down to the difference between the two commands; whether recursion=2 (for lxc ls) or recursion=1 (for lxc ls --fast) is given as parameters to the /1.0/instances GET request.
$ time curl --silent --unix-socket /var/snap/lxd/common/lxd/unix.socket s/1.0/instances?recursion=1 > /dev/null
real 0m0.400s
user 0m0.015s
sys 0m0.006s
$ time curl --silent --unix-socket /var/snap/lxd/common/lxd/unix.socket s/1.0/instances?recursion=2 > /dev/null
real 0m19.213s
user 0m0.012s
sys 0m0.009s
Does anybody have any ideas as to why this happens?
Here’s the output of lxc info: https://gist.github.com/mt-caret/e766ada57e24496a7ffe7962de098dae
