TNSR - clixon_cli hangs when opening

paulwollner66

When opening clixon_cli when logged in via ssh, the cli will hang for several minutes before the cli prompt appears. If I log onto the console via KVM, then it is instant with zero delay. My configuration is extremely simple as I am just testing. A single interface with one BGP session holding a full ipv4 table.

System is in a virtualised KVM instance, 14GB RAM and 8 cores.

If I have a full table, starting clixon_cli via ssh takes a long time. Doing it on the KVM console is quick.
If I drop the table, starting clixon_cli via ssh is quick as well as via the KVM console.

I would appreciate any pointers.

Output of when starting clixon_cli:

Netgate TNSR Version: 23.06-3+tnsr-v23.06-3+jammy

This system is not configured for package updates.

@paulwollner66 try to configure workers, something like this:

dataplane cpu main-core 1
dataplane cpu workers 4

@fractal_boy said in TNSR - clixon_cli hangs when opening:

dataplane cpu main-core 1
dataplane cpu workers 4

Thank you. This worked. Just so I understand, can you comment on what this setting does?

@paulwollner66

The documentation explained it rather well.
