After update kernel to 5.18, there are android emulator performance issue and small delay during booting.
android emulator with android studio is very slow on linux-5.18, but not on 5.17.9.
There are no specific error messages for this situation, but I found a difference between them.
On 5.18, dirty memory was increased rapidly, and kept high usage.
But it also was increased on 5.17, but not kept high usage of dirty memory.
both test used same project and were measured during build -> run emulator -> play video -> close emulator and android studio.
Another regression is a small problem. booting hangs for about 2 seconds.

Here is my system info

Revert to 5.17 fixes these repression.
Does anyone have same problems?
EDIT: After changing filesystem from xfs to ext4, android emulator works normally without high usage of dirty memory on 5.18.
