Results from long running "stresstest"

Just wanted to share some results from a long running stress test of jnetpcap version 1.3.b3 (beta 3).

  • tot = cumulative total number of packets since start of test
  • packets = number of packets processed since previous report line
  • pps = packets per second (calculated)
  • bytes = bytes per second (calculated)
  • hdr/s = header per second processed (calculated)
  • hdr = amount of time to process each header in micro-seconds (calculated)
  • rm = entire process resident memory (not just JVM, but the entire process)
  • pm = packet memory (calculated rm/packets)
  • vm = virtual process memory (not just JVM, but of the entire process)

I thought these are interesting numbers. You can see stable 'rm' column even after nearly 7,000,000,000 packets processed.

Hi Mark, that's awesome -

Hi Mark, that's awesome - out of curiosity, what sort of hardware was that run on?
