So the VM host we were currently assigned to at Linode was shared with other servers that were major IO hogs, causing major slowdowns to service here. I've upgraded/downgraded servers, effectively causing us to "bounce" to a new VM host with much lower IO demands, and this should vastly improve performance. So far, I'm getting astoundingly better benchmarks and results. That said, it may be necessary to do this again in the next day or three to explore other profiles. It takes an hour or two each time, so if you find xepher.net down, I ask for your patience. If it's down more than three hours though, something may be wrong, and please feel free to contact me. Try my xepher42 gmail address or any other way you know to contact me.
