typically want to run on your "performance" cores.
### Specifying file system offset and size
You can specify the byte offset at which the filesystem is located in the file using the `-o offset=N` option.
This can be useful when mounting images where there is some preceding data before the filesystem or when mounting merged/concatenated images.
When combined with the `-o imagesize=N` option you can mount merged filesystems, i.e. multiple filesystems stored in a single file.
Here is an example, you have two filesystems concatenated into a single file and you want to mount both of them, you can achieve this by running
```sh
dwarfs merged.dwarfs /mnt/fs1 -oimagesize=9231
dwarfs merged.dwarfs /mnt/fs2 -ooffset=9231,imagesize=7999
```
