Some jobs do not benefit from increased CPU count and/or RAM, but can be dramatically sped up by faster CPU clock-speeds.It would be great if container performance could be adjusted more precisely, meaning CPU count can be increased without increasing RAM, and CPU clock-speed can be increased without doubling the CPU count.
There are too many different jobs, so having a list of possible configurations will always make someone unhappy. The best solution would be to be able to configure containers precisely, for example:
2 CPUs
4 Ghz variant
4 Gb of RAM
-- or --
8 CPUs
2 Ghz variant
10 Gb of RAM
