Hello, What's the bird version are you using ?
The Bird version 3 is in alpha 0, isn't production usable yet. If you like to test, you can download it on https://bird.network.cz/?download Best regards, Ailton NIC.br/IX.br Brasil Internet Exchange Em 19/04/2023 02:19, [email protected] escreveu:
Hi CPU MHz: 2494.140. I found the BIRD is using different CPU at different time and it’s crossing 100% utilization using command “htop”. It’s happening when I am trying to establish a neighbor where prefix count is more than 106K. I found that BIRD3 support multi-core. Is there any way to install BIRD 3? Thanks & Regards Abu Nasar Md.

If you slow clock speed you are going to run into issues? What is the CPU utilization while the BIRD daemon stopped?

Hi If CPU was normal (idle), then it is unlikely an issue with BIRD. Prefixes are processed as they arrive, so they are delayed only if BIRD cannot catch up and use 100% CPU (note that it is single-threaded, so you have to check load on individual CPUs and not aggregate load, like is default in 'top'). Perhaps the other side send prefixes slowly? -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: [email protected] <mailto:[email protected]>) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net <http://wwwkeys.pgp.net>) "To err is human -- to blame it on a computer is even more so."
