DO NOT MERGE: Testing if benchmarks build is slow with latest asv
xref https://github.com/airspeed-velocity/asv/issues/1026 #44450

We pinned asv in #45886 since the benchmarks build took a very long time to complete after the release.

Testing here if this is consistent, and can be reproduced, or if it was something that happened just once.

Confirmed that asv 0.5 makes pandas benchmarks run super slow, at least in the CI. Closing this, hopefully we can release an asv 0.5.2 soon with a fix.
