Extremely Slow Javascript Performance Across Multiple Browsers

Extremely Slow Javascript Performance Across Multiple Browsers

I am experiencing extremely slow Javascript performance under CentOS across all browsers I have tried. It is to the point that for sites that make heavy use of javascript (such as this one) that my CPU is maxed out for several seconds, and I have to wait for whatever rendering is being performed, making these sites almost unusable. Using the same set of browsers/versions under Windows XP and Ubuntu 6.06 as well as 8.04 on the same machine does not cause any issues. It is to the point that I am trying obscure browsers in hopes that I will find one without issue, but I have not found one that does not suffer the same javascript issues.

"Could it be a graphics issue on the machine? If X is using a completely accelerated driver because the installer didn't know the right one to select (or simply doesn't have one) for your graphics hardware you might see this sort of behaviour as the browser reflows the page during updates.

Though if this is the case I would expect every application to show visible signs of slow performance, not just browsers (though browsers tend to update their display repeatedly while content it loading/updated so they are likely more obviously affected than other apps).

It is worth checking to see what driver your X setup is using and (if it isn't using the right one already) trying to install a better one. This might involve installing a proprietary (binary only) driver."
