Preview video: Emu68 V1.1 with Dumpster feature (update)
In a preview video, Michal Schulz uses the macOS 8.1 boot process to demonstrate how the Dumpster feature in the upcoming version 1.1 of Emu68 improves performance: with Dumpster disabled, the boot process took 84 seconds, but after enabling it, the boot time was reduced to 28 seconds.
And the developer explained: "Dumpster is a new way of destroying and re-using JIT instruction caches in Emu68. Instead of throwing them away right after cache flush, they are reused later if the memory of the JIT block has not changed.
The effect is visible here - macOS is constantly flushing CPU instruction cache, also the JIT cache of Emu68. With dumpster on, the boot time of macOS decreases drastically. The effect is even more pronounced on macOS 7.5.
This is a Work-In-Progress - there are still few things to do before it is going public."
Update: (29.08.2025, 20:11, dr)
The developer has now published the first part of a three-part series of articles in which he provides an overview of the upcoming version 1.1 of Emu68. The first part deals with changes to the JIT scheduler and hash tables. (dr)
