Hi all,

I just wanted to share that we’ve recently done a bunch of write performance optimizations in the mcap libraries. We’ve also updated rosbag2 in ROS 2 Rolling to take advantage of the new library, so writing your bags should be a bit faster than before. You can read about the improvements in Measuring and improving MCAP performance | Foxglove . Please leave any questions or comments about the improvements, or any future improvements you’d like to see.

Thanks,
Chris Lalancette
