Just curious, how big of a difference (indeed, what difference) does
64bit make?
It will make all the difference on a box with 16GB. On a 32bit
machine, you can use a PAE enabled kernel to allow the operating
system to address all the memory, but you're still stuck with a 4GB
per-process limit, which means if this will be a dedicated MySQL
server, you're wasting 12GB of memory.
No, you are wasting 14 GB. The 2 GB limitation is a limitation of
MySQL server.
You're right.
PAE is good but it has a lower performance than a 64 bit platform. PAE
is a workaround if you can't have a 64 bit machine if your application
is only 32 bits and need too much memory.
PAE is useful but it still won't allow any single process to access more
than 4GB of memory. So no use in this case.
