I don't know for sure, but my gut reaction is that 64 MB of RAM is pretty
small for a 1 GB web site. I'd think you'd at least want to double that.
However, it may work with what you have, although probably quite a bit
more slowly.

The web site size to database size ratio is a little hard to predict.
It depends a lot on how much of your web site is indexable text vs.
unindexable content (e.g. images, etc.), and what your config attribute
settings are (max_doc_size, max_head_length). A 1:1 ratio is probably
safe enough for htdig 3.1.5, but databases tend to be bigger in 3.2.0bx.
