Guide to Performance Tuning
|
|
===========================
|
|
The default macOS VM configuration (`basic.sh`) assumes some sane defaults, however this may not reflect the actual topology or peformance capabilities of the underlaying machine.
|
|
|
|
Here's some tunable parameters to get the most of out QEMU:
|
|
|
|
## Memory
|
|
The following line controls memory allocation. The default is 2GB of RAM.
|
|
|
|
Increase this as needed (limited to the real amount of memory in your machine).
|
|
```
|
|
-m 2G \
|
|
```
|
|
|
|
## Cores
|
|
The default configuration enables 4 threads, divided into CPUs with 2 cores each.
|
|
```
|
|
-smp 4,cores=2 \
|
|
```
|
|
|
|
The following example describes all possible topology flags:
|
|
```
|
|
-smp cores=4,threads=4,sockets=1 \
|
|
```
