Hey guys,
i recently recorded some Kinect Motion tracking data using rosbag record and am now playing it using rosbay play (I'm on Ubuntu Oneiric and ROS Fuerte). But it plays really slow (feels like approx. 1/10 th realtime and CPU usage of one core goes up to 100 %) although I only recorded tf (returned from openni_tracker) and one string message:
$ rosbag info day1_cereals.bag
path: day1_cereals.bag
version: 2.0
duration: 2:18s (138s)
start: Aug 29 2012 11:34:24.88 (1346232864.88)
end: Aug 29 2012 11:36:43.07 (1346233003.07)

compression: none [204/204 chunks]
types: std_msgs/String [992ce8a1687cec8c8bd883ec73ca41d1]
tf/tfMessage [94810edda583a504dfda3829e70d7eec]
topics: /object_detections 1085 msgs : std_msgs/String (1085 connections)
/tf 77491 msgs : tf/tfMessage (77491 connections)
Is this performance normal? I would think that it should perform way faster (i use an I7 2,3 Ghz Quadcore)... The number of TF transforms is below 50 (output of openni_tracker plus camera frames plus some object detections). Did someone experience similar issues?
