in this case,


Performance is optimized by SQL.
but in this case,

get_list_or_404(Foo, name__startswith="peter")[:10]

This slice is done by Python.
This is proformance issue.

Is it possible shortcuts can do slice by SQL ?

The get_list_or_404 method is shortcut for simple filters. If you want more complex querysets and if slicing in Python isn't acceptable for your particular use-case, then just do it by hand. It's not worth complicating get_list_or_404 for this situation.
