HI
We have been asked by our IT department to move from our current physical solution to a VM environment. I am not that clued up on VM.
I looked from some benchmark tests to run so i can see a comparison between our live and new VM we have been presented. Please see below for results.
To me the VM looks slower. Can someone advice please and offer advice on any other tests we can run please.
We are running Redhat Enterprise 6.4.
Thanks in Advanced

i recently purchased a dual ross sparc processor kit from someone.
the person listed these items as 133mhz processors, however, looking at bridgepoint's site, they do not make 133mhz processors.
so i was wondering, how can i check the processor speeds? (4 Replies)
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.... (9 Replies)
Hello,
I have a SUN T5240 running Solaris 10 with Logical Domain Manager (v 1.0.3). You can use the "ldm" command to display current resources on the box. Is there away to display all the "physical resources" on the box(i.e.,used and unused). For example, "ldm ls" will tell me what the... (5 Replies)

Hi All,
How can I know whether the server I am connecting to is a virtual or physical one? The server might be having any Unix OS (Linux/Solaris/HP-UX etc.).
Is there any system files / commands which can show these concrete information?
Thanks in advance for the replies.

mbw
mbw(1) General Commands Manual mbw(1)NAME
mbw - Memory BandWidth benchmark
SYNOPSIS
mbw [options] arraysize_in_MiB
DESCRIPTION
mbw determines available memory bandwidth by copying large arrays of data in memory.
OPTIONS -q Quiet; suppress informational messages.
-a Suppress printing the average of each test.
-n <number>
Select number of loops per test
-t <number>
Select tests to be run. If no -t parameters are given the default is to run all tests. -t0: memcpy() test, -t1: dumb (b[i]=a[i]
style) test, -t2: memcpy() with arbitrary block size
-b <bytes>
Block size in bytes for -t2.
-h Show quick help.
USAGE
mbw will allocate two arraysize arrays in memory and copy one to the other. Reported 'bandwidth' is the amount of data copied over the
time this operation took.
Obviously mbw needs twice arraysize MiBytes (1024*1024 bytes) of physical memory - you'd better switch off swap or otherwise make sure no
paging occurs. Needless to say that it should not be run on a busy system.
TODO
Multiple thread support. Better configurability, including using getopt() for parsing arguments.
