first thank you for all of the hardwork on the mod!
I recently moved and i was without internet for several days so I started my minecraft server(MCPC+ 1.6.4 B207) up in offline mode with IC 2_2.0.357 exp, Nuclear Control 1.6.2e + other mods. I noticed when the server finished coming up that it was extremely slow, so I attached jvisualvm and found that the class shedar.mods.ic2.nuclearcontrol.panel.http.Request.run was using an inordinately large amount of CPU time. once I disabled Nuclear Control everything worked fine. I assume that this is the update checker and if so do you think that you could add an option to disable update check in the config file please to prevent this in the future? Let me know if you need any more info.
