The info that you gave is not sufficient to give an accurate answer. What are the webserver? If it's the rocket webserver bundled with web2py than if you have a thread with CPU intensive task it will block the others threads. This is due to the python GIL. Probably you have some loops to process the file, so just use time.sleep inside those loops. Using time.sleep will release the GIL giving other threads a chance to run. time.sleep(.1) should do it.
