rosbag-record-slow-down-real-time-factor-very-heavily

edit

Hi all,

When i launch hospital world(aws-robomaker-hospital-world) and robot model(mir robot), the real time factor is about 1.0, but when i rosbag record /base_pose_ground_truth /clock /mobile_base_controller/cmd_vel /imu/data /odom /points_raw_in /tf /tf_static to record vlp-16 laser data, imu data, wheel odom, ground truth and tf to test slam and localization, the real time factor is about 0.15. Does any body know how to resolve this problem, thanks for your help and time in advance! My OS is ubuntu20.04, ros noetic, gazebo-11.

Best regards
