The query team will need to help to investigate the follow regressions caused by new tcmalloc:
- see if they are real regressions, comparing to 7.0 and 4.4
- see anything we can do to improve the performance or mitigate the regression
- if we can't mitigate the regression by 8.0, are we ok with accepting the regerssions.
See linked BF for more details
