Summary

0001044: pfsetvlan is memory hungry (217Mb on a normal, inactive setup)

Description

There is definitely something grossly inefficient in there. A little run in the debuger could give us a clue.

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND                                                    
 
2760 root      15   0  480m 217m 1104 S  0.0 43.3   0:02.45 pfsetvlan

Steps To Reproduce

1. Start packetfence
2. Wooaaa pfsetvlan is taking all that memory!?
3. Profit

(0001628) obilodeau (reporter) 2010-08-09 16:50	for fun I did a simple test: ran pfsetvlan in the debuger normally breaking right before the main loop with 20 trap handler and 5 trap parser memory usage: 389Mb with 1 trap handler and 1 trap parser memory usage: 53Mb No work at all was performed this means that there is a memory sharing opportunity here! We are probably spawning the threads too early?
