Simple comparison of virtual servers..

  * 2013-2020: vserver Neptun
    * 2GB RAM, 2cpus, 80GB disk
    * Intel(R) Xeon(R) CPU E5-2670 v2 @ 2.50GHz, 16GB cache
  * 2020-: vserver 2000
    * 16GB RAM, 4cpus, 320GB ssd
    * AMC epyc, AuthenticAMD/QEMU Virtual CPU version 2.5+, cache size 512 KB
  * openssl
    * "openssl speed", single cpu benchmark, also depends on how well registers are supported by openssl
  * scp to localhost
    * "scp ... localhost"
