With -t option, you can find translated C program in tmp.c.

Yes, the performance depends on the nature of the program and the
performanc of network. If you are using ethernet, your program must
have the good locality. 

Currently, we are working the next release Omni2, which will include
the new implementation of Omni/SCASH.
