>if you are developing websites for clients don't get into this much detail cause no one will ever appreciate the work you made. That's only true if you don't know how to sell yourself. Considering that you can make people think something is faster just by telling them that it is so, you should be able to get appreciated for actually making a difference. But don't do this kind of thing in the course of your development. If you make something 10% faster without being asked, nobody is going to appreciate that. Fine-tuning and optimization is a separate service, and if you set realistic expectations and then deliver on them, your efforts will be appreciated.
