Note: GTspeed addresses front-end optimization issues
only. If your site still takes a long time to load, an improved server
or back-end code optimizations is what will make a real difference. Read

and is easily remedied by logging out and back in again.
Step 3) Running the plugin
Now it's time to start optimizing!
On your GTspeed status page, enable these options one by one while
checking to see if any of them cause problems for your site:
- CSS Minification
- CSS combining*
- Expires Headers
Note: You must have Minification turned on to enable
When first installed, you won't have any images optimized - This
is normal. You'll need to tell GTspeed that you have images that you
want to optimize. Click on Update Image Library.
GTspeed will now index all the images in the specified directories
(specified in the Advanced Settings) and track them.
When this is done, click on Optimize Images. The plugin
will notify you that this may take a long time. Click
"OK" - GTspeed will now run each image through optimization processes and
replace them with a newly optimized version.
GTspeed is optimizing your images!
This will take a while. Image optimization is a resource
intensive process. You will not be able to access your admin panel
during this time (unless you open up another instance). Your
images will also need to have write permissions enabled, as
GTspeed is overwriting the originals with newly optimized files.
GTspeed cannot optimize images without this requirement.
Test your site with GTmetrix and see the difference in performance.
Step 4) Configuring the plugin
The default settings of GTspeed are sufficient for most Magento installs.
However, settings can be tweaked for sites with more specific needs.
Here's a quick break down of each option:
JPEG/GIF/PNG Optimization Utility
GTspeed comes bundled with three of the best image optimizing utilities
ready to be used with the Image Optimization function. If you would like
to use another utility, place it in:
<magento base directory>/lib/gtspeed/<win32 for windows,
elf32 for linux users>/
and replace the setting with the name of your utility.
Use command line utilities only! And remember to change the command line
options as well.
Note: Mac servers are not supported unless mac utilities can be found.
Image Optimization Paths
This option allows you to add more image directories for the plugin to
scan when it performs image optimization. Separate directories with
The default directories are
Step 5) Optional: Schedule your Optimization
Under the "Scheduled Task Settings" header, you can setup a specific date
and time for GTspeed to re-scan and optimize images (as specified in your
Image Optimization Paths).
Automate your image optimization with a scheduled task!
If ever there's an error, you can input an e-mail address to notify you.
Advanced users: Debug Options
Skilled Magento users can enable debugging outputs to track errors and
update log files. This can provide helpful information for bug fixes if
your site breaks after GTspeed has been activated.
