Hello,

I counter a slowness in running an accounting software on Hyper-V VM which connect to A Dongle reach by network. The scenario as following:

  • The slowness problem appears when the Host is (Windows Server 2016/2019) and the Guest is (Windows Server 2016/2019), The software takes 15-20 sec to run.
  • But problem DOES NOT appear when the Host is (Windows Server 2016/2019) BUT Guest is (Windows Server 2012), The software runs in 5 Sec.
  • ALSO problem DOES NOT appear when the Host is (Win10 OR Windows Server 2012) and The guest (Windows Server 2016/2019), The software runs in 5 Sec.
  • The software runs in 5 sec on any physical machines.

Any ideas about this problem.!

The table explain the scenario.

Thanks in Advance.

    The application developer will be your best resource for trouble shooting application performance problems.

    I need to find the solution.

    Regardless of the operating system the application developer will be your best resource for trouble shooting application performance.

    Hello @Yamen Aljalloudi

    There is no clear system explanation can can be given for a 3rd party application about such small difference in performance. Your best shot is to contact the software company to report this behavior for them to investigate a bug or compatibility issue.

    What I would check, the usual culprits:

    • Any spike in resources when it takes longer?
    • Any relevant events in Application or System Event viewer both on Guest or Host?
    • Have you tried running on some compatibility mode?
    • Maybe some network trace captures while is loading, to see if there is any retransmissions?

    Hope this helps with your query,
