help Looking for advice on a tekkit classic server

[SelectedGaming]

I have been out of the tekkit game for awhile, I used to run a 50-70 average player server and buildcraft used to be a huge problem when it comes to lag and such, I was wondering if there were any solutions to them out now, I see that some larger servers simply have them removed but id really rather not add to the banned items list on my server, any advice on the matter would be great! Also should I re-release my server as a whitelisted server before I go open server? 

 

Thanks for the help!
