I'd take that claim with a pretty big grain of salt. The paper they referenced used an experimental GC without use in production. Who knows how well or bad the default collector in the JVM would perform.
Also, it is not exactly recent. Hardware changes could have shifted the result in any direction.
- Recurecur 10y agoThe exact numbers are worth a grain of salt. The general point aligns well with my JVM experience. Requiring at least double the working set for decent performing GC doesn't seem congruent with running the leanest possible data centers. Regardless, determinism is the really big win. :-)
