ROS delay for both visualization and recording

DamViv

Hi,

I'm using OS-0-128 on linux ubuntu 18.04 with ROS melodic.
I installed the provided ROS driver 1.14-beta 12 and also the OusterStudio (3-6-0-947) compatible with the OS-0-128.

When I display the LiDAR point cloud with OusterStudio everything is quite good at config 512x10 with almost realtime display.

When connecting the sensor through ROS, the display with rviz is delayed by 2 or 3 seconds. I also tried to just reccord the ROS bag (without display), it seems that the data is also delayed.

Other point, when increasing resolution or frequency (1024x10 or Allx20), the resulting point cloud is missing some data and twinkling.

What did I missed about the install ? Why using ROS is delaying so much the data transfert ? How can I deal with this problem ?

Thank you !
