The graph seems to get stuck after about an hour of leaving it open in the browser. It just stays "loading". It may coincide with world save although probably not. Is this a PerfPages issue or a MCServer issue to do with threading or something?

OS: Ubuntu 12.04
Browser: Chromium

Also:

When the restart command is issued, MCServer errors with:

I've noticed very long ticks when the plugin is building pages, especially when a lot of data is being stored. I've thought of some things to speed it up:

• Get rid of the string concatenations and convert to tables, which are squished at the end.
• Take a slightly longer average, say average 10 ticks into one blob that is sent with the page.
