Question : Win 7 and home network

I have a client with 3 home workstations.  2 laptops connect via a wireless router.  The third is hard wired to the router.  The hardwired unit is Win XP SP3.  One of the laptops is Vista Home.  The third device is a Win 7 Home laptop.  All 3 work great to the web, however, the problem is that even while all the necessary drives are shared, the permissions are in place on all machines, the Win 7 machine fails to connect to the other two devices and their respective shares.  They are all in the same workgroup.  I cannot find a reason why the Win 7 device can't, or won't, play nice with the other 2 machines.  What have I missed?

Answer : Win 7 and home network

A single-threaded application will run at full speed in the core it's assigned to.    That has always been true -- even in the original Pentium single-core CPU's with hyper-threading.

What you're probably thinking of is that if you had multiple applications running, the single core would be shared between them (since the CPU treated the hyper-threaded CPU as if it had two cores) ... so the individual applications were sharing the core.    That, of course, is still true ==> if you have an application mix that has all eight "cores" in use (even though there are only four actual cores), then the processing load will be distributed among those cores.

Bottom line:   If there aren't competing demands for the core,  a single-threaded app will run at full speed.    You can force this to be the case by using processor affinity settings in Task Manager so no other application is assigned to the same core.
