The tweakers test is actually VERY telling. With a constant load, how
well do the database scale as you improve the hardware you've given
them to run on. Hardware is cheap, downtime is not. If you can toss
a 16 core server at a performance problem for $20,000 or so, that's
probably way cheaper than watching your main db chug under load and go
down twice a day.
Conversely, telling the bossman you need that 16 core server to
improve performance and seeing the new server collapse under load
faster than the old one due to poor concurrency is not gonna win you a
lot of brownie points.
