Speed of the website is now used as factor in determining its search rank (according to Google). So in-order to increase the rank of the website we should also keep in mind that even if the website has strong SEO it should also be very fast so that it does not hamper the SEO.
In this article I will not write anything about SEO but yes I will surely tell you the techniques to increase the speed of the website by using some tools which are available.
plug-ins are available for firebug. These plug-ins can be used as a basis for determining the cause behind the website being very slow. Key things are as follows:

2. CSS size reduction.
3. Caching the page data both on server and on the visitor's browser.
4. Optimising database tables and queries.

According to Google :
Speeding up websites is important — not just to site owners, but to all Internet users. Faster sites create happy users and we've seen in our internal studies that when a site responds slowly, visitors spend less time there. But faster sites don't just improve user experience; recent data shows that improving site speed also reduces operating costs. Like us, our users place a lot of value in speed — that's why we've decided to take site speed into account in our search rankings. We use a variety of sources to determine the speed of a site relative to other sites.
However, note that the article also states:
Less than 1% of search results are affected by speed criterion.
So page-load speed, in and of itself is rarely
a key factor in SEO.
