Wondering if using buffering on filters could be a solution… I guess
that depends on when packs are recycled when buffering is used.
Buffering does help, yes. When buffering is in use, the shared pack from the
global pool is recycled immediately after the message is written to the disk
buffer. Each plugin that uses disk buffering uses its own packs internally that
don't intermingle with the global packs at all.
