As a performance guy people basically expect me to veto every new idea that might grow the size of anything anywhere. I guess I surprise them when I don’t. The fact is that it’s very hard for me to help make any specific decisions about specific features because only rarely can I assess the value of those features against their cost. Instead I admonish people closer to the problem to do that analysis with questions like:
- Is this feature worth the cost?
- Do you even understand the cost?
- In what dimensions will your customer see the cost?
- Will your customer think it’s a good deal?
Sometimes I can help people understand the cost, for instance in Cyrus’ case I’d be a lot more concerned about the CPU usage and working set of the new additions when they are idle than I would be about the disk footprint. But what I’d really be interested in that cost/value assessment. At what point would it have not been worth cost? Was a quantitative decision made?
Accidental decisions are rarely good ones.
