this is much better on the master branch, made better by commit 2047d3dcbb83bc199600837c0be167f6c0ccab4b
recv is still slower than it should be, but in the ~150us range.

If you can, please point to the git tree in the mean time. I'll take a look on why this is still slower, and release a new version.

glommio = { git = "https://github.com/DataDog/glommio.git", rev = "d3f6e7a2ee7fb071ada163edcf90fc3286424c31" }

It's ok with above glommio version. Thank you!
