Responses not being received by httperf #83
Description
- while using httperf to benchmark a server I wrote, it will just stall and not terminate when a response comes in.
- when my server responds with the appropriate response, httperf does not terminate and show the stats.
- I face this problem for single stats tests like
httperf --server localhost --port 4080and multi stats test likehttperf --server localhost --port 4080 --num-conns 100 --rate 10.
Setup:
- arm64 Mac
- http server running on
localhost:4080 - httperf command used is below(sudo since it is installed globally)
$ sudo httperf --server localhost --port 4080
httperf --client=0/1 --server=localhost --port=4080 --uri=/ --send-buffer=4096 --recv-buffer=16384 --ssl-protocol=auto --num-conns=1 --num-calls=1
