xref #38148
@jbrockmendel #38148 has been reverted, so can you update this to close #37954 and add the release note in 1.2.0 instead. lgtm. the perf enhancements hold here (I think so, just checking).? > lgtm. the perf enhancements hold here (I think so, just checking).?

i timed it at slightly faster than the copying version (likely within the margin of error, dont recall) great. ping on green (not sure what's going on with CI). > not sure what's going on with CI

AFAICT its just backed up.  A lot got merged in a short time! @jreback green thanks @jbrockmendel 

I think we going to backport this @simonjayhawkins (not sure if the regression was on 1.1.5)? no evidence this was a regression. maybe can do some digging post 1.2.0rc0 and maybe backport to 1.1.5 and move release note before 1.2.0

but for now, I would say this is not being backported.
