Over the course of our work with Joomla websites using VirtueMart in scope of providing help with our Product Filter, we often come by requests to increase site performance. And we found that, indeed, without professional interference, sites on Joomla + VirtueMart tend to have poor performance most of the time.
After having gathered enough experience in optimizing performance of Joomla 2.5 and VirtueMart 2.0, we decided to add another service to our spectre - VirtueMart Performance Optimization Service.
To our statistical estimation, average e-shop built on VirtueMart 2.0 takes 3 to 5 seconds to load with caching off. We have managed to bring this number down to 1 second! (speed of php processing of caching off)
Price on VirtueMart Performance Optimization Service is $2 per 1% of speed increase, where current performance of your site = 100%.
For example, it takes 3 seconds for your site to load. We optimize it down to 1 second, which is a 66% increase. We always round down to 5, because 1% is never sensible. So the end result in our example is 65% increase in performance, which, in this case, translates to $130 in price.
Derived from the formula above, the maximum price is $190, which equals to 95% increase in performance (because 100% is rarely achievable, and we round down to 5, remember?), Whereas the minimum price is $0, or nothing, in case code optimization brings no result (or actually, less than 5% increase - so we don't charge for something you can't see and feel). We offer 100% money back guarantee if you are not satisfied with the results.
On average, we optimize our client's websites to 40%-60%, which equals to $80-$120. Our best example is when we increased performance to 12 times of the original (from 6 to 0.5 seconds, which is over 90%) with caching off.
