Circulation at least seems fine under mod_perl, I will do more testing but with a 1000% speed increase, this is definitely where we want to spend some quality testing time.

Could you share your mod_perl configuration? My experiment with Koha last summer under mod_perl occasionally segfaulted Apache, but this might changed in last few months.

It’s a pretty simple set up, purely for testing. And I am totally willing to believe it will still cause problems. But it is certainly worth testing.
PerlRequire "/home/chris/mod_perl-startup.pl"
PerlModule ModPerl::Registry
<Location /cgi-bin/>
SetHandler perl-script
PerlResponseHandler ModPerl::Registry
PerlOptions +ParseHeaders
Options +ExecCGI
</Location>
And my startup script is as simple as
if ( ! {MOD_PERL}) { die "GATEWAY_INTERFACE not Perl!"; }
use lib qw(/home/chris/git/koha.git);
