iControl Assembly Peformance

Joe, fantastic reply. Really appreciate the level of detail. I'm not deep enough into this to replicate your calls but you prompted me to try a couple of things. The most interesting thing I found is it's the first call to the iControl assembly that seems to cause the most latency. In these two examples (calling each of 9 LTMs once and then calling 1 LTM 9 times it's the first call that accounts for approx 75% of the total run time. This is the code and below are the results. I made sure to capture only the time making the connection to the LTM and getting failover state. I would have expected each call to consume approx the same time within a reasonable variance. Not the case... anybody got any ideas why? On the plus side, it implies that I may have some up-front latency on my first call to any LTM in my code, but things get pretty sweet from there on out.

 

 

Module Module1

 

 

Sub Main()

 

Dim arrLTMs() As String = {}

 

Dim my_ltm As New iControl.Interfaces()

 

Dim StartTime As Double, EndTime As Double, dblTime As Double

 

Dim strState As String

 

For Each strLTM In arrLTMs

 

StartTime = Timer

 

my_ltm.initialize(strLTM, "", "")

 

strState = my_ltm.SystemFailover.get_failover_state.ToString()

 

EndTime = Timer

 

dblTime = EndTime - StartTime

 

Console.WriteLine(strLTM & " - " & strState & " - " & dblTime)

 

Next

 

Console.ReadLine()

 

End Sub

 

 

End Module

 

 

All nine LTMs once
