Many users try *-default as their starting point but default config is somewhat different across all the engines. So we should make it same across all engines. Say m=16, ef=128.
It's easier to debug vector-db-benchmark using debuggers when using parallel=1. So we should have a new config in all engines with parallel=1 in upload as well as search
