Message-ID: <2820@phri.UUCP> Date: Mon, 27-Jul-87 17:34:42 EDT Article-I.D.: phri.2820 Posted: Mon Jul 27 17:34:42 1987 Date-Received: Tue, 28-Jul-87 07:24:52 EDT Organization: Public Health Research Institute, NYC, NY Lines: 24 About how many packets per second should I resonably expect to get from a Sun-3/180 file server? Ours seem to max out at about 300 pps or so, but I have no idea if that's a lot or not. I've seen individual clients peak at 5-600 or so. One server has 4 Mbytes and one Eagle, the other has 8 Mbytes with two Eagles sharing a controller (although we currently have the file system laid out such that most activity is on one drive; we're working on fixing that). "Traffic" shows packets to be about 60/30/10 nd/udp/tcp; presumably most of the udp is NFS. I realize there is no single good answer to my question, especially since I havn't told you anything about our workload, etc, but I'm looking for ballpark figures. Is "a lot of packets" 200 per second? 500? 1000? 2000? More? Likewise, disk transfers/second seems to struggle to reach 50. Is that "a lot"? Clearly the fact that our 2-Eagle server doesn't do any better in this department than our 1-Eagle one means that we're really wasting that second disk arm. But, like I said, we're working on fixing that. -- Roy Smith, {allegra,cmcl2,philabs}!phri!roy System Administrator, Public Health Research Institute 455 First Avenue, New York, NY 10016
