fiddler replay limitition problem

[sfro]

I'm using the "replay" function of fiddler and seems I run into a limitition problem.

I wanna “replay” 100 thread of requests at one time as soon as possible，but I found out fiddler can only replay 40 thread of requests in 1or2 millisecond ，then break up for about 100 millisecond or more time then continue prossessing remaining 60 thread of requests.Just like the picture below.

I'm using the 4.6.2.3 version of fiddler,if I turn back to the 4.6.0.0 version,the thread of requests before the "break up point" changed to 48.

Firstly I thougt this problem maybe caused by the performance limitation of my computer,then I reduced the frequency of my cpu from 3.8Ghz to 2.0Ghz,the problem remains,also 40 thread then break up for somtime.

Then  I limit my network speed or disable network adapter,the problem remains the same.

And I changed to another PC,Its  limited to 40 thread also.

I just want a smoothly replay flow list without any big break up or interruption.

Is this the Inherent setting of fiddler or other reason？

Hello,

The most likely explanation for this behavior is depletion of .NET ThreadPool available threads.

You might try changing their number by doing something like ThreadPool.SetMaxThreads(100,100); in OnBoot method of Fiddler Script.
