I could still load pages etc and navigate around as fast, but the numbers on task manager were sky high.įirefox has a reputation in particular for not releasing memory when tabs are closed. I didn’t have time to test them individually as things got hectic after that, but as you say Nicholas, the seemingly innocent extensions were ruining the memory performance of a perfectly good browser. The extensions in question were McAfee ScriptScan for Firefox 14.4.1 and McAfee Site Advisor 3.4.1 Exactly how I would expect Firefox 10.0.1 to perform. Then I closed all but one tab and the memory settled at just under 100,000 kb. Then I closed all but 3 tabs and within 30 seconds the memory was about 180,000. Then I logged out of Facebook and Hotmail, without closing any tabs, and within 10 seconds the memory had dropped to 330,000 kb. I must have had about 15 tabs open and the memory use peaked at 386,000 kb. I opened more tabs with more complex content. So I then disabled the 2 McAfee add-ons and every went back to normal. 400MB with just Google UK open and nothing else. It stayed at that level for about 10 minutes whilst I went and did other stuff. The memory stayed at 418,000 kb and that was it. I right clicked on that tab and hit “Close Other Tabs”. I have to say that there was no loss of performance, but the amount of memory being used was very high for the tab load.
If I was running the same tab load on my latop, I would expect just over half that amount of memory to be reported in task manager. Then it just climbed up to about 450,000 kb. With the two McAfee add-ons running everything was fine until I got to about 8 tabs and then the memory began to increase. I did some very very rudimentary tests earlier at my girlfriends house on her laptop and here is what I found. I asked him to try turning off the McAfee add-ons, which he kindly did.
#MCAFEE SPEED UP MY COMPUTER SOFTWARE#
I am not looking for answers or solutions, merely saying that the same or very similar software used on one computer can perform completely differently on another and now I appreciate that even more having witnessed it for myself. That said, there is no loss of performance and that is what matters most. The memory usage as opposed to being 200,000-230,000kb as it would be on my laptop with 11 beta 2 is about 350,000kb or more. It may be because of the two McAfee add-ons that she has, I don’t know, but I can see now first hand how some Firefox users are having an amazing experience and others are still lagging behind. I am currently on my girlfriends laptop round at her house and I am surfing the net using Firefox 10.0.1. A reader named AC commented on last week’s MemShrink report that Firefox was consuming lots of memory on his girlfriend’s computer (emphasis added by me):
