mod_pep: Handle presence based subscription outside of util.pubsub (fixes #1372) Subscriptions were updated for each incoming presence stanza from contacts. Each subscription change triggered a configuration save, which would filter out the presence based subscriptions and usually end up replacing the existing data with identical data. With many subscribed nodes this adds up to a fair bit of IO bound work that is avoided by keeping them separate.
