We have completed the speed testing of ViArt Shop. As example we took default ViArt Shop versions 3.6 and 4.0.8 with the same blocks, settings and products:
http://hosting.viart.com/~default-4.0
http://hosting.viart.com/~default-3.6
We used a special ApacheBench (Version 2.3) application developed for this purpose. In attachment you can find the results for two main pages index.php and products.php. In the first row 'Complete requests:' are the general amount of requests executed on the page; 'Concurrency Level:' shows how many requests were sent at the same time; 'Time taken for tests (sec):' is a general amount of time to execute all requests and 'Requests per second:' is the amount of requests executed by the system in one second.
As you can see there is not a big difference in speed and 'Requests per second' are executed even faster in version 4. The difference about 10% is visible only when you run one request at a time and there is no much difference at all when you run 5 or 10 requests at the same time.
This is caused by the fact that we added more libraries with different functions and vastly expanded ViArt Shop functionality, for example CMS system is completely different and much more advanced now. The refusal from Zend Optimizer has nothing to do with this fact, we have run the same tests on decoded files and didn't notice any differences.
And we'd like to underline our development team is always working hard on optimizing scripts and queries before releasing any ViArt version.
Regards,
ViArt Team
