Do you think that there is a substantial performance gain by running
Dovecot in a 64 bit Architecture?

64bit arch is faster on floating point operations, not on integer, so
that won't help much. If you have large amounts of memory (>1GB and
especially >4GB), memory addressing will be faster with 64bit. As Timo
noted, I/O is likely to be the bottleneck anyway, so add a bunch of
memory for caching.

I all pedagogikk er det essensielt at pensum presenteres
intelligibelt. Det er et elementært imperativ for alle pedagoger å
unngå eksessiv anvendelse av idiomer med fremmed opprinnelse. I de
fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
