You can mount tmpfs anywhere you like, not just /tmp.  In the past I have
realized considerable speed boosts with databases (such as Texis) that
operated on read-only indices by generating the indices and then copying
them into a dedicated tmpfs area (use the size= option to cap the maximum
size and keep it from sucking virtual memory away from the rest of the
system).

These systems did have quite a bit of paging space configured (usually
10-20GB) so that is of course the tradeoff.

Probably not very relevant then.
