Problem with rosbag for gazebo simulation

I am having problems opening up the rosbag file which was generated while running a differential drive robot in the wg_collada world map with a laser sensor in simulation. I used the gmapping package for making the map. (ROS Fuerte, ubuntu 12.04)

I used the command "rosbag record -a" and I was amazed at the size of the bagfile(32GB!!!!). when running rosbag play, nothing happens and the system becomes dead slow. Why was the size so big..

How do I see the content of the rosbag.

Which commands I should use to see the map in rviz again? also plotting parameters on rxbag or rqt?

Please help

Your bag file is that big because you recorded everything (-a option).

Its taking too long to load the rosbag in rqt_bag even though my system is pretty high configuration (core i7, 8GB RAM, NVIDIA GTX660). And the rqt pluggin hangs every time. Any suggestions??
