when I let numbers of machines use the same master,the running speed is very slow. such as I have three computers A B and C. Then I running the roscore in the C, let the A and B use the the master in the c at the same time.I found the speed of public and subscribe topics is very slow, so as the services. I don't why and how to solve the problem. if sameone knows please tell me. thank you very much.

If A and B have established a connection, then the core is no longer in th chain. There is only a direct connection between them so the speed or network to C is unimportant. Do you have a different experience if you run the core on A or B?

Sounds like a connection problem, Lots of data (Image?) over wifi?
