I'm considering switching from Waveride to Overzold for testing out Bukkit (Minecraft) builds in a environment for all my current players before they are implemented in the official server elsewhere.
At this time, I'm with WaveRide (EDIS) in Austria with a 4GB container, but the I/O hovers around 125MB/s, but they appear to have a somewhat liberal CPU policy (as far as I'm concerned).
Is the situation better on Overzold? As I've heard that Overzold has surpassed many expectations for high-ram oversold providers. Is the I/O better, and how much of the RAM have you been able to access without swapping?
