Currently I am trying to record a video sequence from a 100 fps RGB camera (640x480) using rosbag record. However, I have some problems. Without rosbag record the topic HZ is 100, but when I start the recording goes down to 70 HZ aprox. I don't know which is the problem. I use an SSD drive so it must not be a writting speed issue

Does anyone have an idea of what is happening?.
