https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=41767 --- Comment #9 from Andreas Jonsson <andreas.jonsson@kreablo.se> --- I think that the default value should only be dependent of the number of Plack workers. Maybe it should be on the form C1 + C2 * $PLACK_WORKERS where C1 and C2 are some well considered constants. For instance, C1 = 50, and C2 = 20. I think that a lower value is better but it is safer to start high until we have some more data. I have verified that the backlog-parameter sets the Listen parameter on IO::Socket::UNIX. Since the socket is opened in the master process the queue should be shared by all workers. We also need to consider how to configure Apache for this to be really effective as Apache also seems to be queueing requests. Maybe a lower ProxyTimeout is needed. -- You are receiving this mail because: You are watching all bug changes.
