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.

OK, I will try without JIT then.


Now I have some results.

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.



are these on same hardware running once 32bit or and second time 64bit 
OS ?

I have two core i7 machines
#1 Dell Studio XPS with a 2.67 GHz  920 + 4GB of RAM (2 channel)./Ubuntu 
11.04/x64

  The 109 minutes was measured on machine #1

#2 Homebuilt with a 2.67 GHz  920 + 6 GB of RAM (tri-channel)/Ubuntu 
10.04 x86

 Gigabyte UD5 Motherboard
 The   91 minutes was measured on machine #2.

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.

Python works fine as is. You're welcome to attempt use of pypy, but
last time I tried there were a couple hiccups and the performance
benefit wasn't particularly substantial.
