  • 1.  Helper0-0 takes 60% of all CPU capacity in ESXi 6

    Posted Dec 15, 2015 10:08 PM

    I installed ESXi 6 Update 1 on my 5 year old HP EliteBook 8540p at home. When all VM:s is shut down the CPU usage is around 60%.

    In colum %USED in ESXTOP I see that helper uses around 100.

          ID      GID NAME             NWLD   %USED    %RUN    %SYS   %WAIT %VMWAIT    %RDY   %IDLE  %OVRL

           9        9 helper            158  100.01   94.62    0.00 15711.38       -    0.25    0.00    0.

    if give the command 'e 9' to expand the GID I get this:


          ID      GID NAME             NWLD   %USED    %RUN    %SYS   %WAIT %VMWAIT    %RDY   %IDLE  %OVRL

       32796        9 helper0-0           1  101.98   94.47    0.00    5.42       -    0.06    0.00    0.1

       32797        9 helper1-0           1    0.00    0.00    0.00   99.95       -    0.00    0.00    0.0

       32798        9 helper1-1           1    0.00    0.00    0.00   99.95       -    0.00    0.00    0.0

       32799        9 helper1-2           1    0.00    0.00    0.00   99.95       -    0.00    0.00    0.0

    If I look at the hosts at work helper is consuming almost nothing.

    What is helper/helper0-0? How can I get it to use less CPU?

    I have the same problem.

    HW: i7-6700, Asrock z170m pro.

    Does anyone have a solution to this problem?

    It may be related to power management settings in the BIOS.

    Thank you,

    In vmkernel.log I have a lot of ACPI errors. So it could by power management.

    What shoul I change in BIOS?

    I have also an "older" Asrock MB and I don't have this problem.

    Is there a way to turn off ACPI in ESXi?
