This version of moarperf is also packaged as an AppImage.
If you're on linux on a 64 bit system, you can just download the AppImage file, set its executable bit with chmod +x and execute it. There is no installation process, and you do not need to have a rakudo or any particular modules installed on the system you're trying to run it on.
give every route its own SnapshotList (except index) the index shall next get buttons in the graphs to request snapshots from. this is especially necessary because snapshot numbers and the numbers shown there don't line up neccessarily.
