That's quite well possible, in 2 ways:
1. Install the website amd the database on faster, bigger, more powerful, hardware.
2. Make the programs that run on the web server and application server smarter, so they use less resources.
But since the company doesn't want to spend the money to do it, all YOU can do is to explain to your boss that you need to be allowed (and paid for) more time or get an assistant to do what he wants you to do. It might help to explain also why it's "extremely important".
I'm new here & really hope someone can help. The company I work for uses a website that gets really slow when we all use it at the same time & they don't want to do anything about it. However it is extremely important to me to speed it up to do what I need to do
Is there a way - or more than one way to speed up the website with lots of traffic?
Appreciate any help, thanks
