Additional RAM for server

[Dudesama 0]

I noticed my server only has 100mb of RAM allocated to it. I have created the start.bat file as shown in many tutorials but to no avail since the problem persists. In the server stats window (top left) it literally says Memory Use: 65mb (39% free). My friends and I were playing for a few weeks before the message:' Warning can't keep up, is the server overloaded' continuously displays. Mining in-game also has a delay of 5-8 seconds and often what appears mined isn't (reconnecting reveals this). I am hosting the server on my beast of a PC so shouldn't have problems.

We are playing with around 2 dozen mods on versions 1.6.4 (minecraft) and with 9.11.1.965 (forge)

 

Any help would be greatly appreciated
