Hi Daniel, I could not reproduce it. I did a small test generating an fcd file of about 350MB resulting in a gpsdat file of about 18MB. Both runs took about two minutes on my PC (Windows 7 with Python 2.7.11). What is your platform? There may be some interferring virus scanner or firewall watching your sockets.
