32 or 64 bits?

Just a note, that I posted an article about advantages of 32 bit architecture over 64 bit and why we chose 32 bit at Grono.net.

It's in Polish, but the main point is that in our case Django at 32 bits is consuming about 30% less memory than on 64 bits.

To show the differece, here is output from top command at 64 bits:

VIRT  RES  SHR S %CPU   TIME+  COMMAND
212m  96m 3832 S    0  1:49.61 django '/gallery/3329236/0/'
203m  96m 3120 S    0  1:37.78 django '/gallery/4871149/6/0/'
211m  95m 3832 S    0  1:38.74 django '/mailbox/box/1/'
210m  95m 3824 S    0  1:45.45 django '/gallery/photo/40328359/'
210m  95m 3844 S    0  1:48.43 django '/users/index/'
210m  94m 3848 S    0  1:33.94 django '/users/'

And here from 32 bit:

VIRT  RES  SHR S %CPU    TIME+  COMMAND
68396  62m 3484 S    0  2:06.94 django '/users/433317/'
67716  61m 3488 S    0  1:50.23 django '/gallery/photo/42009962/'
66264  60m 3488 S    0  2:01.94 django '/pub/join/'
65312  59m 3484 S    0  2:08.75 django '/users/'
65148  59m 3508 S    0  1:48.02 django '/users/1533943/friendlist/'
64884  59m 3508 S    0  1:51.48 django '/'
