--- Comment #3 from Timur <gtimur at gmail.com> ---
B column values are used to calculate C, and D uses C. But MSO deletes in 2
secs. 
My Linux is slower but there's a difference.

43all oldest   13 sec
43all master:  29 sec
41max oldest:  15 sec
41max master:  22 sec
43max oldest:  29 sec
52 master:     17 sec
60 master:     30 sec
62 before:     10 sec
62 master:    300+ sec
63 master:    300+ sec
71 master:    300+ sec
7.3+          130 sec

LO never was instant calculating "Adapt row height". 
With all slow downs, it was fast in 6.2 as of commit
1e55a47e89a9d9d6cf9cb3993484022aaf2c097b (not the bad one), but it went very
slow until the master.
7.3+ is faster than 7.1 but it's nowhere near proper time in 6.2.
