处理任务队列的工作线程的创建

工作线程的数量和CPU数量是息息相关的，CPU数量越多则可以创建越多的工作线程数量。

var

si: TSystemInfo;

GetSystemInfo(si);

g_decode_handle := CreateIoCompletionPort(INVALID_HANDLE_VALUE, 0, 0, 1);

g_work_handle := CreateIoCompletionPort(INVALID_HANDLE_VALUE, 0, 0, si.dwNumberOfProcessors);

SetLength(workers, si.dwNumberOfProcessors);

Label6.Caption := IntToStr(si.dwNumberOfProcessors);

for i := Low(workers) to High(workers) do

workers[i] := TWorkThread.Create;
