Someone already mentioned the DNSLookup feature. I can think of 2 other
things:
1) Increase the number of server jobs (via the CHGHTTPA command).
To have the new attributes take effect, restart the server.
Each request may be able handled by more than one server job and
additional jobs 
(up to the maximum you specify) will be started if necessary.

2) Serve html files from an IFS directory instead of qsys.lib and
especially qdls.

I've also tried using SETOBJACC to move CGI programs and DB2/400 files
into 
storage pools but it doesn't seem to help much. I haven't figured out 
how to move stream files there, if it can be done at all.
