I ran Navigation2 on Ubuntu 18.04 with Foxy and Fast-RTPS.

When the CPU was Celeron, this error message always popped out

 [ERROR] [tf_help]: Transform data too old when converting from odom to map

The CPU usage is closed to 100% after few seconds this message showed.

After I switched to a better CPU, the error message hasn't showed up and Navigation2 worked well.

Does anyone know why this happened ?

If I want to stick with Celeron for Navigation2, what should I do ?
