# Why you should batch message processing and how to do it with .NET AsyncEnumerable

**[Event-Driven by Oskar Dudycz](https://daily.dev/sources/event-driven-io)** · 6 min read · 0 upvotes · 0 comments

## Summary

Batching message processing improves performance by reducing network round-trips when handling events from messaging systems or event store subscriptions. Using .NET's IAsyncEnumerable, you can implement size-and-deadline-based batching by bridging it with System.Threading.Channels and the Open.ChannelExtensions library. The approach lets you define a maximum batch size and a timeout deadline — whichever is reached first triggers processing — making it efficient even under irregular event traffic. A reusable extension method wraps the channel-based batching logic back into an IAsyncEnumerable, keeping consumer code clean and idiomatic.
