Computerworld - Editor's note: The person quoted in this story as "Craig Barth" is actually Randall C. Kennedy, an InfoWorld contributor. Kennedy, who presented himself as the CTO of Devil Mountain Software, no longer works at InfoWorld. Given that he disguised his identity to Computerworld and a number of other publications, the credibility of Kennedy's statements is called into question. Rather than simply remove stories in which he is quoted, we have left them online so readers can weigh his data and conclusions for themselves.

Google Inc.'s new Chrome browser chews up more memory than even Microsoft Corp.'s recent Internet Explorer 8 Beta 2, a researcher said today.

"Chrome's a pig," said Craig Barth, chief technology officer at Devil Mountain Software Inc., a Florida-based maker of PC performance-testing software. "Like IE8 Beta 2, it's targeted at the next generation of hardware, not older PCs running Windows XP on a half-gig of RAM."

Barth ran Chrome, the new Google browser released Tuesday, through the same 10-site scenario Devil Mountain used earlier in the week to benchmark the memory footprint and processor thread count for IE8 Beta 2, IE7 and Mozilla Corp.'s Firefox.

In the test, each browser opened the 10 sites -- including media-rich domains such as Boston.com, Channel9.com, CNet.com, InfoWorld.com and NYTtimes.com -- in separate tabs, with links on those sites opened in additional tabs.

Chrome's peak memory consumption under Windows XP was 324MB, slightly less than IE8 Beta 2's 332MB, Barth said today, but the Google browser's average footprint of 267MB was 26% larger than IE8's 211MB.

In Monday's test, IE8 Beta 2 consumed far more memory than other browsers -- 52% more than IE7, for example -- and easily led all others in the dubious honor. At the time, Barth called IE8 "epically porcine."

But even though Chrome tipped the scales even more dramatically than IE8, Barth was willing to cut Google some slack. "It's going to be fat by virtue of what they're trying to do," he said, noting that Chrome eats more memory because it essentially opens a separate instance of the browser for each tab, a design Google said it used to segregate tabs, and the sites on them, so that if one crashes the browser as a whole does not.

"It's going to be fat, but you have got to give Google credit for doing [the browser] from scratch," Barth noted. "It's fat by design, and they come out and say that. 'We're willing to isolate each tab,' Google says, so you know that and expect it."

As he did with the other browsers, Barth also tallied the processor threads that Chrome spawned. The numbers, he said, "befuddled" Devil Mountain.
