We added support for Huge Pages to our sandboxes.

This new feature makes the start of memory-intensive tasks in sandboxes up to 5x faster. For example, reading 0,5 GB of data for the first time after the sandbox starts used to take about 4,9s. It now takes only 0,76s thanks to the memory improvements.

Huge pages let you use 2 MiB chunks of memory instead of 4 KiB chunks, which are the default. Because there is an overhead each time sandboxes need to ask for more memory, being able to ask for bigger chunks of memory means you can ask fewer times with less total overhead.

Huge pages are enabled by default in all newly created custom sandboxes. If you have an existing custom sandbox, you need to rebuild it by calling e2b build in the directory with the e2b.toml file.

Getting started

If you want to try the sandboxes, start here and let us know at hello@e2b.dev if you need any support.
