3. If your Qemu installation supports them, an `-accel` arguments

will speed up emulation. Try `-accel help` to list your options.

- `-enable-kvm`

- `-accel ___` (run with `-accel help` for a list of available options)
|

Once you select an accelerator, I recommend also adjusting the `responsiveness`

mask in shell/evaluate.mu, which controls how frequently the fake screen

updates within the REPL. Smaller values will seem more responsive, larger

Some suggested values depending on how fast your Qemu is running:
|
||||
|
||||
- `-enable-kvm` on a T420s running Linux: `0xffff/responsiveness=64k`
|
||||
- `-accel kvm` on a T420s running Linux: `0xffff/responsiveness=64k`
|
||||
- `-accel tcg` on a 2019 Mac: `0xfff/responsiveness=4k`
|
||||
|

Putting it all together, here's the command I typically use on Linux:
|
||||
|
||||
```
|
||||
qemu-system-i386 -m 2G -enable-kvm -hda code.img -hdb data.img
|
||||
qemu-system-i386 -m 2G -accel kvm -hda code.img -hdb data.img
|

```
