Load Test Failed
I carried out a load test for nope example.
./wrk -t1 -c1 -d10s http://localhost:4242/factor
The config is: NOPE_EPOLL, NOPE_THREAD 2 The bug looks like this:
GET /factorGET /factorGET /factorGET /factorGET /factorGET /factorGET /factorGET /factorGET .... /factorGET /factorGEclose: Bad file descriptor
Same config:
ab -n10000 -c10 http://localhost:4242/factor?q=22

GET /factorGET /factorGET /factorGET /factorGET is just stray output. I have taken it out.
I will do some more elaborate tests to confirm the result. In the mean time, may you try this ? https://github.com/wg/wrk
Thanks!
I did try wrk, and it reported 0 requests as being completed. I am not entirely sure as to why.
