So I decided to try out Plack as in my first reply:
First step tonight will be to read up on configuring and turning on
plack for the test instance. Then I'll toss up doubling cpu/ram
before further tests.
That's where I started to get confused with the documentation on turning
on plack. I started looking at the Wiki and found this:
https://wiki.koha-community.org/wiki/Plack
Is that up-to-date? It's quite detailed.
I noticed there was a /usr/sbin/koha-plack command. A bit of
experimenting showed that running this:
# koha-plack --enable libtest2
will uncomment the line "Include
/etc/koha/apache-shared-opac-plack.conf" in the Apache site
libtest2.conf and then running this:
# koha-enable libtest2
# koha-plack --start libtest2
# koha-zebra --start libtest2
# koha-indexer --start libtest2
starts the test instance libtest2 and I have the OPAC and Intranet up
with a number of starman and plack processes running.
I did some basic manual timing tests on how long it took to load a page,
do a search for a book etc and it does not seem noticeably faster than
the production system running on the same server.
Is the sequence below the right one for shutting down this test
instance?
# koha-indexer --stop libtest2
# koha-zebra --stop libtest2
# koha-plack --stop libtest2
# koha-disable libtest2
Reading /etc/init.d/koha-common it looks like koha-common does all these
things in the right order and I presume "systemctl restart
koha-common.service" does this too. But I have not yet figured out how
to stop or start instance "libtest2" without it affecting the production
system (instance "opac") at the same time.
Then I'll get around to looking at optimal number of memcached, plack
and rabbitmq daemons I should be running.
