- TODO stats for events (packets received, errors, etc)
- custom memory manager is required to avoid performance hit on e.g. []byte alloc/dealloc
-> go-slab
- interfaces conversion in very hot codepaths are costly:
e.g. having r as io.ReadSeeker and converting it to io.Reader e.g. this way:
io.ReadFull(r, ...)
calls convI2I all the time (no caching) which is not negliable
( recheck it is still true after https://github.com/golang/go/commit/3d1699ea:
-> it is still the case; convI2I cost is ~ 8ns - i.e. it is not big for
non-hot codepaths - uncontended mutex lock/unlock is 15-25ns. )
- x/net/trace to trace requests and connection logging (and packets ?)
- packet log; general log -> glog ?
