VPS performance can be really bad, as you know. It can also be quite good.
I posted this earlier today. It has some good performance graphs, in general, comparing a number of VPS providers.

Maybe you can run some of the same benchmarks as the author above and compare?

Hi All,
There is a virtual user "ecoouk" which logs on to the server and runs some scripts. I want to know how much server performance can I gain if I put off all the scripts run by this user.
Please tell me how to analyse how much resources a specific user is using.

smc91c92_cs
SMC91C92_CS(4) Kernel Interfaces Manual SMC91C92_CS(4)
NAME
smc91c92_cs - SMC 91cxx device driver
SYNOPSIS
insmod smc91c92_cs.o [pc_debug=n] [if_port=n] [irq_list=i,j,...]
DESCRIPTION
Smc91c92_cs is the low-level Card Services driver for SMC 91c92, 91c94, 91c96, and 91c100 based PC Card ethernet adapters. When this
driver is attached to a card, it allocates the next available ethernet device (eth0..eth#). This device name will be reported in the ker-
nel log file, and passed on to cardmgr(8).
With the default transceiver setting, the driver will attempt to continuously autodetect the transceiver type (10base2 or 10baseT). There
should normally only be a one or two second lag before the correct transceiver is selected. On particularly noisy or busy networks, it is
possible for the detection logic to incorrectly toggle the transceiver type. If this becomes a problem, it may be necessary to explicitly
select the interface type when the module is loaded or with the ifport command.
PARAMETERS
pc_debug=n
Selects the PCMCIA debugging level. This parameter is only available if the module is compiled with debugging enabled. A non-zero
value enables debugging.
if_port=n
Selects the transceiver type. 0 is autodetect (10baseT or 10base2), 1 is 10baseT (twisted pair), and 2 is 10base2 (BNC, or thin
net). The default is 0 (autodetect).
irq_list=i,j,...
Specifies the set of interrupts that may be allocated by this driver.
DIAGNOSTICS
eth#: interrupt(s) dropped!
Indicates that the driver did not receive an interrupt notification for some reason. The driver will poll the card (with a signifi-
cant performance penalty) if the problem persists. The most likely cause is an interrupt conflict and/or host bridge configuration
problem.
