Network speeds

Hello all,

We have a group of Solaris 8 machines that are having some real network performance issues, they all go through a switch which *should* be set at 100 mb full duplex on every port which goes back to a master switch. I have checked the machines and the NIC cards are all set at 100 full. I had a networking benchmark script that copyed files back and forth from the server and outputted the times it took to transfer them, I did this for a couple of other solaris machines to get something to compare to which arent in the same location as the other group of solaris machines. The windoze admin monkeys had also done the same sort of thing testing performance but looking at the results the windoze machines destroys the Solaris machines for speed. The group of solaris machines had really bad test times whcih were alot worse then the other solaris boxes. I was wondering if there was any test I could do for bottleneck performance and general issues relating to the machines before I confront the network manager. I know theres netstat but I dont really know what im looking for.

Sorry for the essay

regards
will

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.

       See attributes(5) for descriptions of the following attributes:
