httperf --server datahunter.org --port 80 --uri /index.php --rate 100 --timeout 5 --num-conn 3000

opts:

• --rate N              # fixed rate at which connections or sessions are created (Default: --uri=/)
• --timeout X         # wait for a server reaction (completed or failed)
• --num-conn N      # A test stops as soon as the N connections have either completed or failed

Enable ssl

--ssl

Session base

httperf --hog --server=www --wsess=10,5,2 --rate 1 --timeout 5

options:

• --hog                         # httperf to use up as many TCP ports as necessary.(Default: 1024 to 5000)
• --wsess=10,5,2          # 10 session,  5 calls that are spaced out by 2 seconds
• --num-call N               # requests should be sent per connection (default: 1) (server must support persistent connections)
• --burst-length=N        # Each burst consists of N  calls  to  the  server

Troubleshoot

一行 command 就

httperf: warning: open file limit > FD_SETSIZE; limiting max. # of open files to FD_SETSIZE

checking

httperf -v  | grep maximum

httperf: warning: open file limit > FD_SETSIZE; limiting max. # of open files to FD_SETSIZE
httperf: maximum number of open descriptors = 1024

解決

recompile httperf
