Using matplotlib it will be:

import pylab
rows = pylab.load('src.dat')
pylab.save(rows, 'dst.dat')

Perhaps boosting priorities for time critical threads will help.

I don't know about MacOS but for Win32 something like that helps:

thread = win32api.GetCurrentThread()
win32process.SetThreadPriority(thread,
win32process.THREAD_PRIORITY_TIME_CRITICAL)

current_process = win32process.GetCurrentProcess()
win32process.SetPriorityClass(current_process,
win32process.REALTIME_PRIORITY_CLASS)

Well, that's not that simple. Search the web, there are several
tutorials about PostScipt output.
