I haven't done much stress testing, but thus far the engine has taken 
everything my customers can throw at it.

With modern VM being so efficient there's a lot to be said for RAM-based 
databases that wasn't true years ago in systems like Mac OS 9.

My favorite stress-test example (after the time I put the Bible into a 
single field):  One of my customers sent me a gzipped file that was 
about 70MBs.  Of course gzip is very efficient with text data, so I knew 
the resulting file would be fairly big.

But no problem for Rev running in OS X:  I used the built-in decompress 
function to read the 70MBs and the decompressed file was more than 
500MBs -- it took a while but worked flawlessly.

In WebMerge's case, since it generates static web pages, the security 
considerations are no greater or lesser than for any web server.

With CGI there are some additional considerations.  For example, never 
write a Transcript CGI that allows the user to execute statements with 
"do". ;)

Chipp's been working a lot with CGIs lately -- Chipp, got any good 
security tips from what you've been working on?
