This is pretty cool because back in the dot com days I got paid huge amounts of money to do what they did in the first 60 seconds.  I started at $1000&#x2F;day and the phone rang off the hook.  Talked to a friend and he said &quot;double your rates&quot; and I said &quot;WTF?  I&#x27;m not worth $2000&#x2F;day, that&#x27;s crazy&quot;.  He said &quot;double your rates&quot;.  So I did, phone still rang like crazy.  I got up to $4000&#x2F;day and had 5 days&#x2F;week work.  Went to $8000&#x2F;day and got about 3-4 more days and then it dried up.<p>And that is how I made payroll for BitKeeper in the early days.<p>I think it&#x27;s cool that this stuff is far more common knowledge these days.  All I was doing was figuring out if it was CPU, network, disks, file system, vm system, memory.  99% of the time I knew what the problem was in a few minutes, all the real effort was tracking down what program (or programs) were causing it.  Funny enough, most people didn&#x27;t care what cause was, they just wanted to know what to buy to make it not an issue.  Crazy amounts of money being thrown at Sun equipment.
