Very slow disk access to virtual HD file with SmartFileSystem

hexaae · 01 April 2017, 17:18

Strange case: if I use very old WUAE versions (tested from 2.5.1 to 2.8.1) directory access from WB is visibly insanely fast compared to latest WinUAE builds after 3.x.x
When I open my WHDLoad collection drawer full of hundreds of games, contents are almost instantly displayed with pre 3.x.x. Recent versions instead are incredibly slow (something like a real A500!).

Is this "normal" because something is changed in the code for compatibility reasons?

Attached my cfg.

Toni, I can send you a private link with my HD image from my GDrive

To me the latest versions of WinUAE with AFA OS are very fast, see the attached video, while unpack a large archive i opened folders with hundreds of PNG icons.

How is that reply going to help? It makes no sense..

Start by switching off vsync. You are not going to get fast anything with vsync on.

Sorry, my typo: I meant g-sync. With or without v-sync WUAE emulation option nothing changes. The speed difference is huge between before vs 3.x.x+...

Attach logs first. (tick debugging in paths panel, boot to "slow" wb, quit, attach bot log files)

Ok, attached bootlogs.
Booted, opened the "slow" drawer full of WHDLoad games and then quitted emu.

What is last "fast" version? (non-beta, after found, it is time to find the exact beta).

What do you mean by g-sync? If you use g-sync, never enable any normal vsync option, it won't work. Correct option is "variable sync" option.

Tested all old versions: last "fast" was 3.0.0 (2014.12.17)
Slowdown started with 3.1.0.

3.1 betas are temporarily back. http://www.winuae.net/files/b/winuae_3100bX.zip (X=3 to 23). First two were winuae_3010b1.zip and b2.

Tested 310b03 and found the slowdown let me try b1 and 2...
Uhm... even with b1 I can find the slowdown.

Try adjusting CPU idle setting. Idle logic changed completely in b1.

You're right Toni: changing CPU Idle settings (lowering it to the left) solves the problem with slow drawers opening!
