chore: use Linux container CPU quota (#266)
Browse files Browse the repository at this point in the history
Go is not cgroup aware and by default will set GOMAXPROCS to the number
of available threads, regardless of whether it is within the allocated
quota. This behaviour causes high amount of CPU throttling and degraded
application performance.

Fixes: #265
