GOAL SUGGESTION: AIM TO KEEP MEMORY USAGE BELOW OR AROUND 100 MB WHEN 3 JAVASCRIPT AND FLASH HEAVY SITES ARE OPEN keep up the good work guys almost there :) Reproducible: Always Steps to Reproduce: 1.www.myspace.com 2.www.youtube.com 3.www.hulu.com ** 3 tabs, 3 sites (listed above), same window ** Actual Results: www.myspace.com 91 MB www.youtube.com 106 MB www.hulu.com 122 MB 122 MB is the total memory usage when these 3 tabs are open. bringing that number down just 6 MB per tab would exponentially increase multitasking capabilities. Expected Results: 122 MB is the total memory usage when these 3 tabs are open. bringing that number down just 6 MB per tab would exponentially increase multitasking capabilities. other than that, great job with 3.6 rc1 very responsive and snappy here to help thanks alot :)
