How to have control over the hourly fishbucket snapshots in order to reduce the CPU and I/O impact?

Hi, A couple days ago I posted a question regarding hourly CPU spikes on Universal Forwarder. It was found that the hourly fishbucket snapshots cause a brief CPU and I/O spike. My new question: In order to reduce the CPU and I/O impact, do we have any control over this process? Anything we could do that would result in reduced CPU usage? Thank you.
