windows - C++ Threading CPU usage issue on older PC -


i need expert's advice , opinion on thread usage. have simple "plugin" dll has 2-3 threads, each of them started _beginthreadex().

a thread looks this:

unsigned __stdcall thread(void* parguments)   {       while ( true )       {         //         sleep(3000);     }     _endthreadex( 0 );       return 0;   }

now, thread not have high cpu usage, works expected on new pc's, have discovered on older pc's dual core cpu's example running 2-3 instances threading method take lot of cpu. cannot explain myself why, , don't know do.

i have tried createthread() also, not make change. can please guide me how create thread run same way on pc's ? if i'm doing wrong, please explain me what...

thank you!

_beginthreadex wrapper createthread. , if experience high cpu usage it's problem "do something" code has nothing method used create thread. inspect code profiler , race conditions. note snippet posted broken because loop has no break , therefore method has unreachable code.
