Looking for a way to 'benchmark' CPU performance on my TFS

[diegozenho]

Hi, I'm using google translator, sorry if a grammar error occurs, a friend of mine said he once saw a system here in otland, which was doing the same thing as "perf" parsing everything and seeing what is consuming more cpu, I was wondering if anyone here knows about this system, my tfs is pulling a lot of cpu, thanks even more!

'perf' is better than this system.
I got it on kasteria.pl. Not much code, reports are automatic, but with 'perf' you get much better information what is wrong with your server.

Depends on your kernel, I had to run:

sudo apt install linux-tools-5.0.0-23-generic

I also had to run this to let it read kernel address maps:

sudo bash
echo 0 > /proc/sys/kernel/kptr_restrict

Then you can run "pgrep tfs", choose the process id, then I use "perf top -K --pid TFS_PID", -K is to disable kernel symbols from the list.
