Hello my dear readers.
Today I have a question for all of you. What platforms (32bit or 64 bit) do you use for your servers with more than 4Gb RAM? I’m asking because recently we‘ve hit few really weird bugs in Linux kernels 2.6.18 to 2.6.22 and all those bugs were P ... Continue reading »

В частности linux-image-2.6-amd64 но сама система 32bit, и никаких проблем с PAE. Понятно, что каждый отдельный процесс не сможет съесть в такой схеме более 2GB памяти.

Any updates on the 32-bit versus 64-bit. Do you see any memory / performance degradation with the 64 bit? I have 8GB RAM and I am deciding if I should go with 64 bit or downgrade to 4GB RAM and get a 32 bit OS.
Thanks.

In our case we had python processes. On 64 bits one process used about 95MB RAM, on 32 bits about 60MB (there are a lot of pointers inside python).
So, by downgrading to 32 bits we could fit 30% more requests on one machine. And our next bottleneck became CPU rather than RAM.
We also wondered if 32 bits (with 8GB RAM) are slower than 64 bits. But some home made benchmarks showed that the performance degradation isn’t a problem (the results showed that 32 bits are 3-5% slower).
We tested also some combinations like 64 bits kernel and 32 bit userspace, but finally chose 32kernel/32userspace.
And what you finally chose and why?
