Details of the issue:Issue: Server constantly complains it is falling behind. Server does not settle down from this behavior after any period of time. Server population is never above 6 people all working out of the same area, no complex machines, blocks or mods are used on the map as of yet. A fresh map was attempted to still no positive result. Navigating the world, server will complain approximately every 20 - 30 seconds that it is falling behind, even with only 1 player on the server.
Upon starting minecraft server all appears to load fine. Upon entering the world a bit of lag occurs as expected for the load. However allowing this to settle and allow all region chunks to load in does not alleviate the issue.
Fresh install of FTB Infinity on fresh install of ubuntu server 14.04.3 LTS. Server performs as expected and system is tested as working as intended. Java installed (both 1.7.0 and 1.8.0) however issue shows on both versions. Tried a variety of java arguments to little-to-no improvement. Details of java arguments are as below.

Logs are available upon request however this is basically a completely fresh install and the logs to me don't appear to indicate any thing specific.
A /tps command shows under non-lagging circumstance averages of 20-21. When issue occurs, tps shows as low as 1.5.
Thoughts on how to diagnose and or improve the situation are welcomed. Sorry if I've left anything out.
