Select RMI or other libraries

I am writing an application that has a server and a lot of clients. Clients and the server send messages to each other. I am going to use RMI, but:

1. I will have 1000 requests from clients to the server per second. Is it normal for RMI? How about performance?

2. I know there are many different libraries (JIRO and other). Myabe some of them can solve this task better. For example, in RMI I should use synchronized, maybe some of them can synchronize access to objects automatically.
