Yes, not supporting 64-bit hosts is one of the known limitations of psyco. Being stuck with Python 2.6 is another limitation. But, latest bitbake appears to be quite fast even w/o using psyco these days. Especially with parallel parsing on multiple cores... -- Denys ^ permalink raw reply [flat|nested] 7+ messages in thread

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 ^ permalink raw reply [flat|nested] 7+ messages in thread

Both are using the same type of disk Western Digital Black 1 TB and have 1333 MHz memories. I tried Ubuntu 11.04 / x86 on machine #1 using an external e-SATA Seagate disk some time ago. I do not have the exact figures, but It was within minutes of machine #2, so I think it is safe to assume that the extra time is there due to the lack of JIT compiling. End of this week, I hope to try on a 4.4 GHz (overclocked) Core-i7 2600k/Ubuntu 11.10/x64. Still only 1333 MHz memory unfortunately. -- Best Regards Ulf Samuelsson ^ permalink raw reply [flat|nested] 7+ messages in thread
