OpenVZ VPS configuration samples

Sample A
Hoster runs Virtuozzo on a Dual Core Opteron 175 CPU / 4 GB RAM with 32-bit SMP kernel and probably dozens of virtual hosts. First impression of delivered performance is ok, but scant resources make it almost unusable for even basic server tasks. To me this is more a „jailed“ environment to host a few static websites. Guaranteed memory of 90 MB per VPS.

Sample B
Hoster runs Virtuozzo on a Pentium 4 CPU at 2.4 GHz / 1.5 GB RAM with 32-bit kernel and probably a handful of virtual hosts. First impression of delivered performance is ok and second impression is too, well configured and performing. This is the hoster and configuration that this website is currently running at. Guaranteed memory of 515 MB per VPS.
