any special setup for mod_perl 1 + apache 1 under

that's probably the reason why i rarely see mod_perl
offered in share dhosting environment.
no, mod_perl is just unsuitable for shared hosting by design. it has
nothing to do with virtual hosts.
a- mp caches code into apache. it can take *a lot* of ram.
there's no effective way to manage memory in these situations -- you
either preload everyone's stuff into apache at start, or apache takes
a performance hit each time a child reads code for the first time.
because apache children expire after x requests, in a shared
environment you'll get almost no speedup - and a potential
performance decrease.
b- as clinton noted previously, the way mod_perl handles namespaces
can cause overlap issues
As I said before, you're best off to just install apache2 and mp2 *in
addition to apache1*. you can keep all your apache1 stuff running as-
is on port 80. just run/configure apache2/mp2 to run on an alternate
port - like 8080 , and proxy the necessary requests to it via
mod_proxy on 80.
