The audit daemon only keeps one event "in flight" until its consumed by
all sources. This is partly a limitation imposed by CC requirements
that loss of audit capability have a known limit on potentially lost
events. Generally it gets rid of events quickly.

One question to ask would be if auditd is writing to disk? If so, maybe
changing the writeback scheme would help. Besides that, you can change
the priority of auditd and/or the dispatcher.
