Following the WCAG Guidelines would "affect performance" as long as they
are validating the XHTML & CSS, with fewer or no errors. Theoretically the
page should load faster as well as improve positively possibly impacting
SEO, SEM.

You may also try an online (free) performance page analyzer (E.G.
www.webpagetest.org) for actual measurement and numbers. There are plenty
more available using the searching the term "web page performance test".

If there's concern for performance, give them ammo and a target to improve
upon.

Without a URI and details all anyone on WebAIM can do is speculate. Ask
more questions...


Good luck,
John Middleton
