Kir,
and what about IP masking in countries file format? Is format really strict?
Does this feature actually work?

512M RAM should be enough (even 256 can go, but I'm not sure).
The more RAM the better speed, although more that 1G will not
help in your case I believe.
Disk subsystem - the faster the better. Anything from IDE/66 with
7200RPM HDDs to hardware SCSI RAID - depends on how much do you
want to spend on it.

Most relevant value is key_buffer_size. Set it to 1/4...1/3 of
available RAM.

It depends on what do you want.
One scenario can be such: first time, run index and
wait it to be finished. Then, you can run it incrementally,
start it every day from cron, and stop (with index -E)
after, say, 20 hours, and run index -D to put the things
just crawled to the main DB. You chould check time needed for
index -D and change your timings accordingly.
Or, you can do the same, but on weekly basis.
Or, you can wait till index will finish every time (and so,
don't use index -E, index -D).
> 4) Any other performance issues I should know about?
If you use IDE HDD and don't know what is hdparm, take a look
at it.

Reality always seems harsher in the early morning.
