One of our servers is running approximately 15 catalogs under one
instance of interchange. It runs fine...the only thing i don't like is
that reconfig requests are too quiet (errors aren't displayed; you have
to check the error logs to see what died). Well, that and installing a
global sub/tag/etc requires a full restart (which takes about 15
seconds...not long enough to freak out vlink, but long enough to
possibly cause a noticeable delay to visitors).
One could run interchange with the --test option before attempting a
restart, if one were paranoid about a global change they'd made. But
for the most part, the only thing that could go wrong from changing a
catalog, is that that catalog would die. It's not easy to accidentally
have one catalog break another.
CPU- and RAM-wise, the server in question is a dual P3/733 with 512MB
RAM. Idle time is consistently 80% or higher (load average atm: 0.04,
0.10, 0.08) and memory usage is about 560MB (71MB of it swap), with
apache, tomcat, mysql, and interchange running. Keep in mind, though,
that a number of the catalogs don't get much traffic at all. I wouldn't
hesitate to run 5 busy stores on it, but i'd have to look at performance
at that point before recommending more.
