OK, a couple of things: CoCreateGuid takes its time too, try with this one instead, it is supposed to be a tad faster, since CoCreateGuid just calls this other API function.

Declare Integer UuidCreate In rpcrt4.Dll As apiUuidCreate ;
	String @Uuid

apiUuidCreate(@m.Uuid)

http://msdn2.microsoft.com/en-us/library/ms688568(VS.85).aspx

"The CoCreateGuid function calls the RPC function UuidCreate, ..."

If you don't mind giving away the MAC address in the GUID, try this one, MSDN says its a little faster:

Declare Integer UuidCreateSequential In rpcrt4.Dll As apiUuidCreateSequential ;
	String @Uuid

apiUuidCreateSequential(@m.Uuid)

http://msdn2.microsoft.com/en-us/library/aa379322(VS.85).aspx

"For security reasons, UuidCreate was modified so that it no longer uses a machine's MAC address to generate UUIDs. UuidCreateSequential was introduced to allow creation of UUIDs using the MAC address of a machine's Ethernet card."

"Note The UuidCreateSequential function tends to be slightly faster than the UuidCreate function. When the performance of the generation of a UUID is a significant consideration, the UuidCreateSequential function may be used."

So there you have two other options to try, and still waiting to find out what you are into...
