That clarified it thank you so much!

Hi Eric,
boost::beast is a low-level c++ http protocol library that's hosted at
https://urldefense.com/v3/__https://github.com/boostorg/beast__;!ewrCk7WT9Do!NranHr9vbRm-Hn46zxjyw_uw4s_fDmS2pHoR1ngtDKMIanoncHDkD2dh8Y6u$ . Radosgw uses this library, along with
boost::asio, as the basis for its 'beast frontend'. The motivation
behind this frontend is its flexible threading model and support for
asynchronous networking. The civetweb server's thread-per-connection
model has been a major limitation for scalability. With ongoing work to
extend the asynchrony of the beast frontend into radosgw's request
processing, it'll be able to handle more concurrent requests with fewer
thread/memory resources than civetweb.
In nautilus though, the beast frontend still has this
thread-per-connection limitation, and its performance is comparable to
civetweb's. I expect we'll make more noise about it once we're further
along with the async refactoring and start to show the real wins. I hope
that helps to clarify the situation!
