Opencart PHP programming - speed up website with many products and categtories
My site has 30,000 - 40,000 items being inserted through an automatic upload of items through a CSV file. The items and the categories are slowing down the site.
I currently have a programmer that has created the link between the CSV file and the opencart site. However, the opencart site is moving extremely slow. It is so slow that it will not even load sometimes.
He is attempting to speed up the site right now. I have posted this job in case he is incapable of finalizing the website.
At the moment, I am willing to purchase an extension to speed up the site as well. Ultimately, I want this site to perform well using the following tests:
I want the site to pass Google Page Speed testing. Preferably, with a score higher than 90.
I also want the site to pass webpagetest.org testing.
We would like to see all As for this test... at least a passing grade of C in all categories.
I look forward to receiving your bids.
