> "I didn't want to rewrite everything from scratch, and definitely, I didn't want to handle all edge cases for epoll. My choice was to use libuv. The architecture I opt for: use 16 cores out of 40 for networking, having 16 'uv_loop' each running on its own thread. Callbacks will be passed from F# to each 'uv_loop' instance. The event loop will call them after parsing the bid request in C11."

Looks like libuv directly in C11? (not F# as before edit).
