Simulating Latency

Hello,     We are looking to simulate latency on the network to test an application in a WAN environment.     Would it be plausible looking to iRules to investigate if this is possible? ...

I was thinking for loops. I tested this in the lab, on my BigIP this equates to about 58 milliseconds of delay:


when CLIENT_ACCEPTED {
  set y1 [clock clicks -milliseconds]
  for { set x 0 } { $x < 100000 } { incr x } {do nothing}
  set y2 [clock clicks -milliseconds]
  set time1 [expr $y2 - $y1] 
  log "For loop time is $time1 milliseconds"
}
