Upload speed generally does not matter, mine has always been steady at ~1 megabit per second. I never really upload much at all, and it has never seemed to effect my performance on servers at all. As GK said, MC is now downloading more than usual, ~150 KB/s If his internet can only handle 165 KB/s then there is not much wiggle room there. Sk is looking into the reasoning of the increased bandwidth.
Didn't sk fix the download speed taken to download ? I mean that he disabled the modular power suit explaining that this was causing the laggs.
If you're getting this now when powersuits is removed, then you have too much in your area and your network cannot handle it.
Still having the issue sadly, it was never because of Power suits, it is only happening in the morning to about 4:00 PM PST. After that it goes back to normal. Its not my base, I had kyl check. EDIT: My lag goes away in the nether... So maybe, if I could have someone check my area again?
