SuSE 10 32bit Hardware interupts on VMWare ESX 4i

Hi!

Does anyone know how a high percentage of Hardware Interrupts does affect a Linux system? any why does it generate hardware interrupts?

The affected system is a SuSE 10.2 32bit running 2.6.16.60-0.33-vmi #1 SMP Fri Oct 31 14:24:07 UTC 2008 i686 i686 i386 GNU/Linux

procinfo shows that the vmxnet driver has the highest HI.

Code:

Linux 2.6.16.60-0.33-vmi (geeko@buildhost) (gcc 4.1.2 20070115) #1 SMP Fri Oct 31 14:24:07 UTC 2008 4CPU [xxxxxx]

vmsync

VMSYNC(9)							   Open VM Tools							 VMSYNC(9)

NAME

       vmsync - vmware kernel module

SYNOPSIS

       modprobe vmsync

DESCRIPTION

       This  is  a  Linux  kernel  module.  It	isn't  backed  by  a  virtual hardware device, so it must be loaded manually. It is depended on by
       vmware-guestd(8), so ideally it should be loaded prior to starting vmware-guestd(8) (though vmware-guestd(8) can function without it). This
       module is used for freezing and thawing the filesystem.

OPTIONS

       vmsync has no options.
