Remote bag file fetch costs more than it's real size, and with some layout ，progress bar loads very slow

Description In Chrome network, for example, a 2GB remote bag file may costs 5GB data requests, much more than it’s real size. And I found the progress bar loads very slow sometimes. Our network is ok, I don’t know what causes this, maybe high frequency topics, or a layout panel that consume a lot of resources?

• Version: 1.31.0
• OS: Mac / Ubuntu
• Data source (e.g. bag file, mcap file, rosbridge, ROS 1/2 native): a remote bag file
• ROS distro (if applicable):

It’s hard to say exactly without seeing how the data is structured in the file. If you can share the bag file with us (privately via email) we can take a look at reproducing the issue and seeing if there is an appropriate fix to apply. Without the file it is hard to guess at what might be happening.
