[Quickfix-developers] fromApp calling requency

[Mangalore, C. <cha...@cr...>]

Hi,

I was doing some R&d with the quickfix library,
I have a quickfix simulator implemented which acts as an exchange.

When I ran my application I see a 2-3ms of difference between the two 'fromApp' calls. 
P.S: I am just print a messge "fromApp invoked" in fromApp()

Couple of doubts below:
1) How is the 'fromApp' callback invoked from the quickfix library? Why I am seeing a delay? 
2) Is the invocation of 'fromApp' is multithreaded or single threaded?


Any details would be vey much appriciated.

Thanks
-Channa
