Haiku sometimes lags

I’ve got a beta of Haiku. It can sometimes lag. Why Haiku lags sometimes?

Haiku should run even with lower hardware preferences.
It would be helpful, if you post more details about your machine.

It’s not just you. The bug has been long fixed in the nightly builds but beta3 isn’t out yet.

What kind of lags? If disk IO lags or browser freezes, it can be #15585.

Mouse lag sometimes, since (unsure, not to blame you) your appserver changes.

Any way to reproduce? It can be caused by hrev54788.

Sadly i havnt found any way to reproduce it yet.
