If you build tor against OpenSSL 1.1 on that target you will get a massive increase in performance due to support for the ARMv8 hardware AES acceleration. This requires 0.2.8.x from the maint-028 branch (or master if you're brave) since I recently fixed tor (again) to compile with this version of the library, but the changes will be in the next 0.2.8 release candidate.
