Last time I checked memory usage was alright

So I've been running a tekkit classic server for some good months with my friends on a laptop, and It's been running surprisingly good, both fps and performancewise.This has been until the point where we've built a large automatic cobblestone factory (it is the largest and most complex of our structures until now, and we've been trying to do everything) and since that, the chunk in which the factory is located began to lag increasingly after a while (It ran good for a time), and at the moment it lags horribly, making it unplayable.Naturally I wouldn't worry a lot but this one chunk is next to the server city, and we can't even mine in it. My specs are AMD A8- 6410 Radeon r5 graphics, two video cards, AMD Radeon r5 and r5 m330 respectively, and a total of 4 gigs of ram. The server setup is java -Xmx3G -Xms2G -jar Tekkit.jar nogui pause Any help would be greatly appreciated, thank you.
