There written async-iso...
What is it? Is it affect for games?
Thank you...

[Bositman]

It's a branch to speed up iso reading speeds on slow HDDs or from USB sticks

[billyash]

Is games gain speed?...cos when compress iso game using Linuz Iso CDVD fps drop 1-5 fps in slowest condition...

[Bositman]

It's what I said, faster reading on very slow hard disks or usb sticks. Nothing else.

[billyash]

Ok... Thank you very much

billyash:
The branch is an optimization on how PCSX2 loads ISO files.
Regular PCSX2 does it linearly, stalling the whole emulation process until the DVD sector is read.
This behavior is bad for all situations where the source medium can't be read quickly enough.
Gigaherz changed the ISO reader to be asynchronous, which is the way it should've originally worked.
The change will mostly be noticable when loading ISO files from external USB drives or similar.
It's just a refinement to ISO loading that was long overdue.

In short, the new branch uses a smoother ISO read code.

is it mean boot iso faster?...

.. Yes
