The original + implementation used sockets to transfer data from the main thread + to the worker threads, and didn't allow any thread to be assigned + more than a single piece of work at once. The new implementation + avoids communications overhead by making requests in shared + memory, avoiding kernel IO where possible, and keeping more + request in flight at once.
