Hi, i've got vibe.d base web-server serving requests. load-tests showed, that there is some responses (spikes) taking long time comparing to others.
It is very annoying cause i need in some sense soft realtime, every request should be handled within certain time.
does anyone encounter / suffer from this problem? could anyone suggest something?
as far as I understand this spikes caused by GC work, am I right?
also thus spikes increased under load.
