Response time on heavy communication is much slower than under XP
I'm developping a GUI application that communicates with an electronic device through Ethernet. Basically the communication are strings through a telnet channel. We have some performance issue under Windows 7 (x86 and x64) and therefore we did some measurements. We send the same command to the device repeatly (500 times) and we measure the time from the sending until we received the answer back:
It seems that launching a Virtual Box is doing something around network that DECREASE the response time.
I googled around and saw the network throttling mechanism, I tried to disable it (with a reboot), and it has no impact.
Can somebody help me by pointing me on any mechanism in Windows 7 that can slow down response time in the network? I know this is a setting somewhere, because launching a Virtual Box allows me to have the correct performance.
Any help will be very appreciated,
