Performance degradation after upgrading to 4.4

hi all,

we encountered the same performance degradation with version 4.4.3, so we downgraded to 4.2.12 and things run fine again.
I see no evolution anymore in this SERVER ticket #51104 since Jan-27 this year from David Gotlieb, it’s status is “Waiting for user input” . What input does that user need to provice? About the situation with 44.3 ? Cos we were running 4.4.3 and had the exact same issue.

I see that the currently latest available version is 4.4.4 but hard to figure out from its release notes if anything relevant has been changed or fixed with regards to this (quote David Gotlieb) “internal to MongoDB cluster communication” problem.

Does someone have any update, please ?
