How can I optimize a plugin for WU usage?

I just saw the fuzzy search plugin had an update “1.26.9 - optimized the WU usage”. There were a few others I’ve seen recently. What’s up with that? How can I optimize the WU usage for my plugins?

I would say Rico that it may be about batching API calls and other actions within how a plugin is designed. It may vary vastly from plugin to plugin.
