I have been using my Mac for for many months without any problem. But recently all of a sudden the Mac became insanely slow.
I opened Activity Manager to see what was happening. For three processes SystemUIServer, UserEventAgent and loginwindow, the memory gradually increases and reaches upto 2 GB for each process. This completely hangs up my Mac.
I tried the following:
- Restart Mac
- Restart Mac in safe mode
- Manually kill the processes
- Remove Date and Time from Menu bar (this was supposed to be the problem for the SysteUIServer process's memory according to many users)
- Removed the externally connected keyboard and mouse(some had suggested this for UserEventAgent's memory)
No luck with any of those. The moment I log in, the memory spikes up.
Any idea what the hell is happening? Please help.

First of all: High Memory-Usage is not a bad thing in itself - the goal is to have a performant system and it can accomplish that by using RAM.
That you Mac slows down is more likely a problem that a process or an App is hogging Memory and not correctly releasing it, forcing the system to use Swap-Memory (on your Harddrive) and thereby slowing your system down, but that is just one possible scenario.
I think it is necessary to differentiate that because i think you are looking at the wrong place for your problem.
Other Possibilities could be wrong File Permissions, I/O errors of your Harddrive or SSD, timout issues for some process or App (Google Drive, Dropbox etc), corrupted chaches or swap files.
