I would expect you'd be able to run some of the less intense mods fairly well. You may struggle as worlds become busier, especially with a lot of entities and chunks loaded. I wouldn't recommend running a server on that system.
The fact is that your processor isn't exactly that strong. In order to play more intense stuff, you'll need to turn your settings down, or upgrade your hardware.
