I think I need to clarify my earlier post. Many people have sent me suggestions consisting of 'use ps -aux' to find the problem. The problem is that I tried that weeks ago (I've been programming in Unix for 8 years) and the only oddity that I can find is init using 12% of the CPU time, which since I have only one NeXTdimension, it's hard to find out what the noraml is for a ND machine (it's .1% or so on my NeXTcube). I know this has something to do with the problem (I meant to mention it int the last post), but I can find absolutely NO reason for this machine to be doing that kind of loading. For what it's worth, the machine uses NFS to mount 2 other machines (4 partitions total), and is a NetInfo client, and uses NTP for time service. None of those should have anything to do with the problem. On a slightly unrelated note, I upgraded the ND board to 20Mb and it slowed down even more. I was told by NeXT that it didn't matter what order the SIMMS went in (since we have no documentation, and never got any,even after harassing them for it), but apparantly something doesn't like 4x4+4x1. I am NOT a happy NeXT customer right now, I've gotten nothing but the runaround even getting what I consider to be "normal" information that should be in the manuals, (some of which we have been unable to get out of NeXT even though we should have gotten them with our machines). As someone doing research and development work for a major university (The University of Texas at Austin) it would be hard for me to suggest anyone buy a ND machine at this point. The concepts are great, someone needs to teach NeXT how to support a machine. I can't even get them to answer a simple question (like SIMM order) wihtout going through my "official support person". This is NOT a company I want to deal with. Chris -- | Chris Petrilli ____ | petrilli@gnu.ai.mit.edu ``Quayle is a bozoe.'' \ / | I don't even speak for myself. \/
