There should not be a revelant gap of perf between using and not using chroot.

try putting also /etc/hosts and /etc/nsswitch.conf into the chroot. Is
it better ?

if you have only one chrooted env, you can setup mysqld to write its
unix socket into the chroot (ex:
/path/to/chroot/var/run/mysql.socket). Then the socket will be
available from inside and from outside the chroot.
If you have more than one chrooted env, then you can't use unix
socket. You'll have to use TCP on localhost.
