[Spread-users] Using Spread in a single system for local IPC

I have a question regarding the use of Spread inside a system with soft 
real-time requirements. 

There are a group of processes residing in the same machine.  The 
communications scenarios are two:
1) Sharing some data with many processes through shared memory.  The 
sharing process would update the shared memory and let other processes 
access it in read-only mode.
2) Passing and receiving commands from processes through dedicated FIFOs.

Spread, however, has a more straightforward API and can be used for both 

My doubt is if its performance would be comparable to the native IPC 
system calls, given that the processes require soft real time
