Newest Update Lag Problems

[Skween]

I updated my launcher to the newest version yesterday and I've been having serious lag issues. I have no idea what's causing the problem (it shouldn't be my internet connection or computer in general), and I've never had this problem with Tekkit before. Any ideas on what could be causing this/how I would fix it would be greatly appreciated. Thanks in advance!

Yes I noticed this as well. When I test my modpack through the default mojang launcher it runs smoothly but when I play through the platform i get block lag, hit lag, entity lag, everything.

Well i have almost the same issue i do have more lag than i used to get but my computer after playing tekkit for about 10 minutes will restart the network and kill the internet. It does not do this with snything else i run it just started this with the last installment of the new tekkit. It happens every 10 minutes or so was wondering if it is the comp or tekkit itself. Any help is good help.

After an update of the launcher and tekkit lite, (I'm on a MacBook Pro btw) whenever I tried to run tekkit lite or another modpack it would just go to a black screen and then just close, but I finally got it working, and it just LAGS so much,
