slower payments with clboss running

[marimes]

I am running node 02d695b01c7a6909e716c863fb39bc5fb7bbdc3824b7fdce53adc593e5be080e73 and have re-started clboss after several months of running the node without it. Clboss has been probing the network for three days straight and keeping topology at 100% CPU load. I also notice that payments (small and large) take significantly longer (20-30 s) than without clboss running (2-10s). Is this expected behavior, or must I change anything in my configuration?

What version of CLBOSS are you running?

lightning-cli clboss-status

[marimes]

I am running clboss version v0.14.1-rc2 over lightning version v24.08-modded.

I've noticed topology being very busy (~90-100% CPU) on my node as well. My node has two cores, so one process being 100% consumes half the total available CPU ...

How many cores does your system have?

[marimes]

The VM has four cores. I am okay with having one core at 100% as long as it's productive (I assume there is a lot to measure for 200 channels). The problem is the responsiveness and waiting 20-30 seconds for a payment to clear, which usually takes only a few seconds.

I totally agree, I was making sure we weren't simply starving a single CPU ...

Another resource I've had to tune is memory ... any chance your system is paging?

I run sar -W 60 in a window to make sure pswpin/s isn't more than single digits ...
