TimeSynchronizer too slow for PointCloud2 and LaserScan.

I used messaged_filters to sync messages from a pointcloud2 topic and and a laserscan topic, process, and publish it. But the publish rate is too slow for it to be of any use, even without doing anything in the processing bit. About 5-8 seconds for each published.

Does anyone know any alternatives?

Are the PointCloud2 and LaserScan coming from the same sensor?

If they are from separate sensors, you should try the Approximate timesync policy: http://www.ros.org/wiki/message_filters#Policy-Based_Synchronizer_.5BROS_1.1.2B-.5D

They are from separate sensors. I'll let you know if its solved after I try it.
