Faster and more reliable Exchange Online Management using PowerShell V2 Cmdlets

I have a script in which I need to get the FolderPath for the Calender folder in each mailbox, for which I use Get-MailboxFolderStatistics. To test the performance I measured the time doing Get-MailboxFolderStatistics and Get-EXOMailboxFolderStatistics for all mailboxes. With the new and supposedly faster cmdlet this took 4x longer! Only when I ran the test a second time was it slightly faster (like 25%) than the old cmdlet, because it apparently uses caching.

If we cannot assume that the new cmdlets are at least not slower than the old ones, then I don't see the point in switching to them. So far I'm not impressed.

I also noticed that Get-Help -Online will open the wrong URL (it uses https://docs.microsoft.com/en-us/powershell/module/exchange/exchange-ps-v2-module/ when it should be https://docs.microsoft.com/en-us/powershell/module/exchange/powershell-v2-module/)
