Do you mean ngx_http_perl_module ? Yes:
1) do not use $r->XXX values in number context:
my $i = $r->variable('counter') + 1;
my $i = $r->variable('counter');
2) $r->XXX values do not have terminating '\0',
exceptions are r->filename and $r->request_body_file.
my $path = $r->variable('name');
open FILE, $path;
open FILE, '/path/' . $r->variable('name');
3) if perl was built without multiplicity interpreters, then it will
not recompile external modules
4) perl code should not do long blocking operations, i.e. connect, read,
DNS resolving, etc.
However, I plan to add special method to $r->connect()/$r->read()/$->write()/
$->resolve() and non-blocking operations with MySQL and PostgreSQL.

No, nginx simply will not get control from perl.

OS scheduling and CPU cache trashing. As usual in large number of processes.
