MacBook Pro slows down considerably after 15 minutes of use?
I'm using this laptop for an Airmessage server and a Minecraft server. When it boots up it is completely fine, but after 15 minutes or so the cursor starts to lag, the Minecraft server keeps putting out “Can't keep up! Is the server overloaded? Running X ticks behind" after inevitably crashing, even though nobody is using the server ever and there are only minimal datapacks. The Airmessage server isn't too resource intensive but messages feel laggier. Whenever it restarts it goes back to normal for another 15 minutes or so.
The battery was a replacement and had 20 cycles. System information labels the battery as “Normal" condition. It is plugged in at all times. It has 6gb of ram that was harvested from other computers since the original ram and another ram replacement failed before that. It has been doing this lag thing for years, long before the ram failed. Storage is barely used at all since I removed plenty of user accounts It never feels like it gets too hot. Do you know what the problem may be and how to fix it?
