grinder

Grinder is a trivial load-tester.

e.g.

echo http://localhost:8080/ | ./grinder -bar -stats -max 2000 -rounds 100000

"Hit http://localhost:8080/, 100,000 times, at most 2,000 parallel requests, use a progress bar, and show me stats at the end"

Usage of ./grinder:

  -nocolor
    	Don't colorize the output
  -nodnscache

  -timeout duration
