RE: Building Slow Development Systems (On Purpose)

Kerry,

        Your most likely to get flamed from the development side of the
list.  Naturally developers want the same or similar setup as production
and to a point I agree.  Yes they should have sufficient disk space for
a full dump of Prod so that they can mimic it.  But I'm a fan of
recycling the equipment that we were using in Prod into Dev environments
so that the developers are working with slightly poorer equipment that
the production folks so they see the problems in a similar light.  BTW:
as much as we all hate raid 5, I like it in dev.

Subject: Building Slow Development Systems (On Purpose)

Hey guys,

   I did a post yesterday about a conversation I had regarding  
"encouraging" developers to write tighter code by intentionally  
hampering development system capabilities. Specifically, using a very  
small buffer cache which basically turns all the lio's into pio's,  
thus (theoretically) encouraging developers to minimize lio's. There  
have been some good comments already but I thought I would poll you  
guys.

   My initial reaction to the idea was that it was just plain crazy.  
But for some reason, over the last several days, the idea keeps  
popping up to the top of the stack in my brain. I fully expect to get  
flamed a bit, but I'll try not to take it personal. I would request  
that you give it an hour or two to roll around in your brain before  
you respond. It is a bit counter intuitive and it is certainly counter  
to what I've always thought of as the "ideal", which is DEV being an  
exact duplicate of PROD in every respect (I'm still waiting to see my  
first one of those by the way).

   Note that my conversation was about DEV environments, not QA  
environments. QA environments should, IMHO, always be as close to PROD  
as possible (same stats, etc...) But maybe there is an argument for  
"encouraging" developers to minimize lio's.

   Feel free to flame away.
