Right now in the datacenter CPU usage is considerably more expensive than RAM usage. Ram consumes comparatively little power, whereas burning hot CPUs+GPUs are the reason datacenters are favored near cooling water and power stations. 2.48 vs 12.23 seconds for Java and Go is a big deal for how many solar panels or tons of coal are needed to run an app on Xeon or Epyc instances, whereas 1.7GB vs 0.4GB for Java and Go, a 4x difference in low-power memory usage, is not so big of deal.

At any rate I did link to the full table so everyone can see the mem usage, source listings, etc.
