I forgot about one thing.
I'm attaching simple .prg code which can be linked with MT HVM
which shows the speed overhead inside current hb_inetRecvLine().
Please check the speed difference when you executed compiled
program without any parameter and with some non empty parameter.
In the second version simple .prg function prg_recvline() is used
with hb_inetRecv() to emulate read ahead buffer.
BTW I'm interesting in Windows results for above code so if possible
please I would like to ask desktop windows and WinCE/WinMobile users
to send here "total client time" for above test code executed in both
modes.
best regards,
Przemek
