Bandwidth is different between two computers

Hi,

I ran a bag file of point clouds and filtered it with pcl library (C++).

In the first compourt: For the original point clouds topic the rate (by calling rostopic bw /<topic>) was about 30MB/s. After processing with pcl the rate was about 650Kb/s.

With the same pcl code which was running in the first computer and with the same bag file the rate on the second computer was about 8MB/s.

What it makes it to be more weird is that when I sliced almost 99% from the original point clouds with pcl the rate of the 8MB/s never changed. No matter what I tried to do.

I saw with Rviz that the pcl code is actual worked.

Both computers' ros distro are melodic.

Thanks for your help.
