In this week’s episode of Two-Minute Tech Tuesday, we'll talk about the Transit Buffer. The Transit Buffer is a Varnish Enterprise feature that reduces transient memory consumption by pacing backend fetches and only storing data at the pace that the client can consume it.

In this week’s episode of Two-Minute Tech Tuesday, we'll talk about Memory Governor. The Memory Governor is a Varnish Enterprise feature that is part of Massive Storage Engine. It limits the total footprint of the Varnish worker process while sizing the cache dynamically.

In this post I will shed some light on Varnish Cache memory usage. In particular, we will examine the malloc storage backend and tune jemalloc for optimal usage.
