Building a custom x11 image on a 32 bit Ubuntu 10.10/psyco-dist took 91 minutes. Building the same image on a 64 bit Ubuntu 11.04 without psyco-dist took 109 minutes (The last machine was an i7-920 w 4 GB RAM) The first might be the same, alternatively it was a machine with 6 GB RAM. = It takes 20% more time on a 64 bit O/S. -- Best Regards Ulf Samuelsson
