I think that is fairly typical for hardware that can run Debian armel
user space,
which nowadays means mostly ARM926 based SoCs like sam9 or f1c100s.

While there used to be popular ARMv5 and ARMv6 implementations that are
a bit faster like Kirkwood or IOP13xx, those have mostly been replaced by
ARMv7 or ARMv8 chips in practice, leaving Debian armel for this bottom
end of the scale.
