Factors that can
adversely
affect RM Easimaths:

1.

Old or corrupt version of Adobe Flash Player

2.

Too

many applications running

If your computer has a lot of programs and services running, this will reduce the memory
and processing available for running RM Easimaths.




Third party toolbars in

your
internet brow
ser

can slow the browser

down
.
If you
have
installed

browser helpers and other toolbars (they are often bundled with
updates for existing applications that you have such as AVG, Java and Flash Player
),
please uninstall them

via Uninstall a Program in the Control Panel
.




Similarly, too many 3rd part
y add
-
ons
/plug
-
ins

enabled in the browser will affect
its
performance. Add
-
ons can be disabled when not required. (RM Easimaths only
requires Adobe Flash Player to be enabled.)

Many applications install
processes that run in the background from when your
computer starts up and check for updates for an application or driver that is
installed on the PC
;
or
are designed
to speed up the start
-
up of
an

application.
Some of these use a lot of your computer’s m
emory/CPU and can cause other
applications to run slowly.


You can check which processes are running via Task Manager (hold CTRL + ALT and
press Delete then select Start Task Manager) then select the Processes tab.

A
process can be stopped by clicking o
n its name then the End Process button.
You
should be careful to check whether a process is necessary for the running of your PC
before ending it, by first searching the internet for the process name and checking
its purpose. Restarting your PC will rest
art any processes ended via Task Manager.


Some common processes that
use a lot of system resources

are those for iTunes
(
http://support.apple.com/kb/HT3960
) and Spotify
-

Spotify.exe and
SpotifyHelper.e
xe
; also Skype.


If particular processes use a lot of system resource and are rarely used, then you

may wish to disable the
m
, or
prevent

them from automatically running when your
PC starts up. This can be done by running MSCONFIG, then selecting the proce
ss(es)
you wish to disable.




Having
multiple antivirus programs installed

is not advisable as they will slow down
your computer’s performance since the antivirus programs will not only be
monitoring the internet activity, but each other. Select one antivi
rus program, and
uninstall the others.




Viruses and malware

If your computer is infected with viruses or malware, this will affect its performance
in addition to possible security issues. Please ensure antivirus definitions are kept
up
-
to
-
date and regul
arly perform a scan of all the files on your computer.




If
temporary files and cookies have built up

on your computer, or there is
corruption in your temporary files, this can slow down the browser.
Clear all the
coo
kies and temporary internet files from
your computer.

Depending on your PC’s configuration, you may find that RM Easimaths runs better in
one browser than another. If you experience performance issues in, say, Google
Chrome, please try Internet Explorer or Mozilla Firefox
instead.



3.

Internet speed

and bandwidth


When an RM Easimaths session is run, data is transferred back and forth between the
Easimaths web servers and your computer using a secure internet connection (HTTPS).
HTTPS
connections
can be much slower than HTTP

because all the data is encrypted and
because data integrity checks are more stringent in secure connections


If your internet connection is slow, or you have reduced bandwidth
, or a high ping
(jitter) rate,
then this will affect the speed at which the RM

Easimaths application runs.

Most domestic internet connections a
re asymmetric, which means that

the download
speed is higher than the upload speed.

If you have a poor upload speed, this will affect
RM Easimaths
,

as it communi
cates in both directions whi
le
running.

To check the speed of your connection, go to
http://www.speedtest.net/

and click Begin
Test.
Your connection needs to be at least:

Download:

2Mbp
s

(Mbps =
megabits per second
)

Upload:

256kb
p
s

(kbps =
kilobits

per second)


If you experience performance issues with RM Easimaths and have done everything you
can to speed up performance of your PC and internet connection,
please

check whether
anyone else in the house is using the internet
at the same time


on a computer/tablet,
phone, gaming machine such as Xbox, etc. as you will be sharing the available bandwidth
with them.

pecification

The minimum specification for Flash Player is here:

but it must be borne
in mind that ‘minimum’ here means that Flash Player will just run, and for the
application to run well, the specification must be exceede

Graphics/Video card using memory

A computer's video memory is
RAM

dedicated to the task of processing graphics.

Some
computers have integrated
(
"onboard"
) video cards

which do not have

separate

video
memory, but rather use

a portion the system's main

RAM
.

Stand
alone, or dedicated
video cards that plug into the motherboard have their own video memory
.
When
checking your computer’s specification, it’s important to know whether/how much RAM
is being used by your video card as there may be less RAM avai
lable to your
application(s) than the maximum installed.


You may find this YouTube video helpful in checking what RAM is used by your PC’s
video card:
