Want a performance evaluation program for a UNIX

[TOHRU ASAMI]

We are seraching a performance evaluation program for a UNIX since
we are planning to buy a new UNIX system. Our current system is
UNIX 4.2bsd on a VAX-11/780 with 8MB main memory and a FP5200 array
processor. Our aim is to get a UNIX system which is more suitable 
to real time operations than the current system.

If you know any information on such kind of evaluation programs,
could you inform me on it?

My mail address is as follows:
	{ihnp4, seismo, mcvax, hplabs, ukc}!kddlab!asami

Thanks in advance.
