[info] AboutAsserts:
[info] - asserts can take a boolean argument
[info] - asserts can include a message
[info] - true and false values can be compared with should matchers
[info] - booleans in asserts can test equality
[info] - sometimes we expect you to fill in the values
[info] AboutValAndVar:
[info] - Vars are variables, and may be reassigned
[info] - vals are values, and may not be reassigned, analogous to final in Java

You can try with QByteArray that shares same QString's interface but is more suitable for performance issues.I obtain 36 ms (qt 5.2 clang) vs. your original 57 ms (on my machine) with this code:

QByteArray allDatab;
foreach(const int & value, values) {
    allDatab += QByteArray::number(value);
    allDatab += '\n';
}
QString result(allDatab);

and 29 ms with this version (that maybe confirm your assumptions about setNum):
