Hi all,
I've got working soft, using pure libwebsockets for HTTP-serving,
ws-serving, HTTP- and websocket- clients. Using
LWS_SERVER_OPTION_EXPLICIT_VHOSTS
Now Im trying to plug libuv _only_ for better perfomance.
There are problems when creating second vhost (for listening
ssl-websockets). Segmentation fault at freebsd/mac on. gdb shows

#0  0x000000080112d8fc in uv_fileno () from /usr/local/lib/libuv.so.1
#1  0x00000008011329bc in uv_poll_start () from /usr/local/lib/libuv.so.1

I tried different parameters, the same. I dont understand last two calls,
cant find proper sources. Should I dig deeper or maybe before it you can
help with only 2 questions

1. It there a reason to use libuv/ev for better perfomance at all?
2. Between these two should I choose libev because it was tested
better and embedded
in a larger number of projects?

Thank you for answers,
and for lws specially
Alex
