ros publisher Node speed
I am running a ros publisher/subscriber node, which receives a single image from a /image_pub topic , do some processing and publish the results on /results topic. The image_pub topic is publishing at 20Hz but my publisher/subscriber node runs at 12 hz(i found it using rostopic hz /results). Is there any way to improve the speed or tell my program to run at 20Hz. At start it was running at 20Hz. Then i turned off my Linux for lunch, came back and restarted my program. Now its running at 12 hz. I have restarted it again and again but still runs at 12 hz. Any solution..?
