The factors affecting the maximum frequency of topics in the ROS1 bridge

Create an issue to discuss the factors that can affect the maximum frequency of topics in the ROS1 bridge.

In my system with a 2.4GHz CPU core, the ROS1 bridge experiences crashes and message loss when the message frequency exceeds 100 Hz.

In my system with a 3.6 GHz CPU, the ROS1 bridge can easily bridge messages at 1000Hz.

What are other factors, apart from the CPU, that affect the performance of the ROS1 bridge?

Just an update: the ROS2 bridge can crash easily when we set history to keep_all.
