DDraceNetwork - developer

What is the point of the placement new here? m_pCharacter = new(m_ClientID) CCharacter(&GameServer()->m_World);

This is from CPlayer::TryRespawn

DDraceNetwork, a cooperative racing mod of Teeworlds - ddnet/ddnet

the idea is basically to reuse the same memory every time

ah, I missed the overload

don't those numbers took too round to be true?

looks like some estimation :D

Doesn't really show me a clear hog like I hoped though

what tool did you use?

17:22

in OS software I'd use valgrind --tool=callgrind

17:22

and then look at it with kcachegrind

deen: I don't think I can profile ddnet with callgrind on the servers, way too slow

true

I was hoping to see where a GETINFO attack actually causes lags

we have a great tool with low performance overhead for that at work, but unfortunately not open source :/

deen: some dynamic translation like callgrind or call stack sampling?

call stack sampling, but looks much more accurate and useful than the one you showed :D

and also returns you a dot file in the end

deen: is it something you made inhouse? maybe you can convince your ppl to open source it

:o
