IE 7 100% CPU While In Lorebook

[Avaton]

When I go to any page in the Lorebook (even the home page) IE 7 hits 100% CPU usage and stays there. It takes up to 20 seconds to click on a single link. Browser lag of this kind equals a broken site. Not just annoying but virtually unusable.

When I leave the Lorebook site everything returns to normal and IE drops to about 2-8% CPU usage.

Happens on all my home computers and my work computer too.

All computers that I've seen this on are running XP SP3 with all the current updates and drivers while logged in as Administrator.

What is the Lorebook doing that causes IE 7 to max at 100% CPU?

[Avaton]

Is anyone looking into this? A simple "We are aware of the issue and are checking into it." will suffice. As it stands now the Lorebook is virtually unusable.

Haven't been able to reproduce this behavior though I have yet to find a SP3 machine available. Haven't heard of anyone else reporting this either. Can you provide a full rundown of specs:
* Full browser version
* Made any changes to the default IE/internet settings?
* Full OS version (XP Pro? Home?)
* Anti-virus program/version
* Firewall(s)?
* Filtering software?
* Any other plug-ins, browser toolbars, etc. that might be in between your browser and the net?

Again, can't reproduce the issue here (or on my home machines either), but we'll try to mimic your environment as best as possible and see if something shakes free. If you do have any browser toolbars, plug-ins, etc. running, try disabling them when hitting the Lorebook. You can also see if clearing your browser cache helps; might be a stale file in there causing an issue.

Running IE 7 with XP SP 3 here and it peaks out at 18% but quickly drops back down. This is with a dusty version of IE that gets used about once a month that has no plugins.

Is IE 7 out of beta yet? I've had the first public beta for quite some time, and haven't noticed any updates to that, but I find it hitting 100% CPU on quite a variety of sites. It especially likes to choke up on Ctrl-F type searches (as opposed to a search engine). I'm running it on a Core2 Duo with 4 GB of RAM (64-bit OS, 64-bit version of IE, all 4 GB are in play) and it still happens.

tl;dr: IE7 has CPU usage issues

Yes, IE7 has been official for some time now; you might be thinking of IE8.

IE7 has been out of beta for almost a year now, and has had several patches.

They currently have a beta of IE8, if that's what you mean.

Beat me to it! :P

Good thing my housing is in the Shire. I need a hole to hide in. >_>

Just tried it with XP, SP3, IE7 here. Works fine for me; computer is a 3.2ghz single core, 2gb ram, wireless set up.

Do you have any plug-ins or other stuff installed? I'd also say do a very thorough virus/adware/malware scan.

Also, have you ever looked into getting Firefox? I didn't even know people still used IE.

[Extrife]

Firefox!

you'll never use IE again

[DYMongoose]

Personal preference. I myself loathe firefox. Opera and Chrome are OK. Honestly though, I'm yet to have problems of any kind with Internet Explorer.

Full browser version for all computers: http://www.neoncranium.com/IEInfo.png

Changes to default IE settings: Turned off Clear Type, Turned off Automatic Image Resizing, Disabled Phishing Filter, Turned off Search From The Address Bar.

System info for this computer: http://www.neoncranium.com/MySysInfo.png
System info for work computer: http://www.neoncranium.com/WorkSysInfo.png

Anti-Virus Software: None on this computer. Norton on work computer but I don't know the version. I tried disabling it and stopping the service but it didn't make any difference. AGV on wife's computer. Disabled it but it made no difference.

Firewall: Windows Firewall on all computers. Tried disabling it but it made no difference.

Filtering Software: None.

Browser Toolbars or Other Browser Sillyness: None on this computer. Work computer has the Google Toolbar so I uninstalled it but it made no difference. Wife's computer is loaded with more IE toolbars and junk than I have room to list here. I tried disabling them but it made no difference.

Installed IE Plug-ins: Java, Shockwave Flash on this computer. Same for work computer. Wife's computer is loaded with junk but still has the problem so I didn't even bother. Disabled them all but it made no difference.

Browser Add-Ons on this computer: http://www.neoncranium.com/MyAddOns.png
Work computer has even fewer.

Task Manager processes on this computer while Lorebook is loaded in IE: http://www.neoncranium.com/MyTaskManager-Processes.png IE apparently doesn't take advantage of dual-core processing so this 50% reading is actually a single core at 100% as seen here: http://www.neoncranium.com/MyTaskManager-CPUUsage.png

Task Manager processes on work computer (old single core CPU) while Lorebook is loaded in IE: http://www.neoncranium.com/WorkTaskM...-Processes.png

The problem seems to be the worst while moving the mouse around on the page. If I let it sit still for about 10 seconds the CPU usage drops to zero. Unfortunately, moving the mouse is one of the things I really need to do while using the site HEHE!

If you need any other info just let me know.

Edit: Oh I cleared my cache files too on all machines but it made no difference.

Do you have any mouse software loaded? And check...some of that **** will load itself without consulting you. That what it sounds like it happening since it's worse when you use the mouse.

Nope. The mouse on my computer is using the standard built-in Windows mouse driver. It's a plain vanilla Microsoft Wheel Mouse Optical. No software loaded for it at all.

Work computer had some mouse software installed for a goofy Logitech trackball but I removed it due to it being supremely annoying. The problem with the lorebook was there both with and without it though.

Again, I'd like to stress that this is happening on all of my home computers and work computers which range from an old 866Mhz Dell laptop to my computer which is very modern. Different routers, different network configurations, different Windows installations, some computers loaded with junk, some computers only one step above a fresh reformat. I can't find a computer that the lorebook doesn't peg IE at 100% when the mouse is moving.

Had a buddy from another game (Eve Online) try the Lorebook (he doesn't play LoTRO) just to see if his machine has the same problem. It does. I don't know his details other than he built it himself.

Well I'll be a beardless dwarf... I thought you were just making stuff up now (my apologies), so I tested it out. Sure enough, moving the mouse causes the CPU usage to rise to a max of about 30% over only text, slightly more over normal links, and 95%+ over the javascript links and menus. In fact, a few times it caused Task Manager's "Stay on top" setting to forget it was supposed to be the top window, and gave that privilege to Internet Explorer.

Bad news bears

[DYMongoose]

Wait, there's more!

It seems this isn't a Lorebook-specific problem... other sites do the same on differing degrees... Engadget.com and GMail both got up to 99%, Google News to 40%. It seems that moving the mouse at all takes CPU power, and JavaScript / AJAX even more.

May this be noted as my first official "strike" against Internet Explorer 7.

Are you on XP SP3 as well? To date, I cannot reproduce this on any machine here though none of them are patched up to SP3. I know SP3 had some bizarre issues with AMD processors and OEM distros, but I haven't heard of it causing IE7 flakiness. Right now, SP3 seems to be the only major delta between the machines here and Avaton's.

Yes, I am on Windows XP SP3

[Avaton]

Why on Earth would I make this up? *boggle*

I set up a new web server today running Windows 2000 Server with SP4 and all the updates. It's running the latest version of IE 6. The lorebook works fine on it with the CPU jumping up to 100% only if I run the mouse up and down over the links on the left side of the screen. As soon as the mouse stops moving the CPU drops to 2%.

Looks like the IE 7 and XP SP3 thing is probably the culprit.

Anyone having this issue with Vista? I haven't upgraded any of my machines to it yet so I can't test it...

Edit: Oh and my friend in Eve is running XP SP3 and IE 7 as well.

[Majesto]

Anyone having this issue with Vista? I haven't upgraded any of my machines to it yet so I can't test it...

I can confirm that it does do this in Vista w/ SP1 as well. Although it only pegged one core of a dual-core system. So overall it capped at 50%, and dropped to 0% when I stopped running the mouse over the left navigator menu. Seems it has to do with the javascript that pops up the sub-menus in the mouse-over events.

But why you'd want to keep running the mouse over those menus just to get your CPU maxxed out, I have no idea...

[Avaton]

I don't. On my XP SP3 IE7 machines it stays at 100% long after the mouse has stopped moving. I tried to fraps it but because IE is pegging the CPU at 100% (50% on a dual-core is the same thing if the software doesn't take advantage of the second core) for several seconds, fraps chokes and gives me garbage. I tried setting affinity to opposite cores for both programs but it made no difference.

Obviously this is confusing to some so I'll break it down to be perfectly clear:

1. Lorebook works fine on my Windows 2000 Server with IE6. The only way to slow it down on that computer is to run the mouse up and down over the links on the left side of the screen. Obviously this isn't how I browse the Lorebook. I was just doing it to see if there was anything I could do to make it choke on that machine. Using the Lorebook normally equalled no problems at all on that computer.

2. Lorebook chokes almost to death on my XP SP3 IE7 machines. All of them. Even at work. The CPU maxes out for several seconds after moving the mouse. When I stop moving the mouse it takes from 5 to 20 seconds for the CPU to drop back down. When I first started using it I killed the IE process a few times because I actually thought something about the Lorebook was locking it up.

3. I don't have access to any Vista machines so I was asking if anyone with Vista was having the same problem as XP SP3 with IE7 (number 2 above).

Sorry for being unclear.

[Hazmat]

IE7, XP 32 bit SP3, dual core 8400 @3.0GHz

I don't think it is XP or IE7 since mine never goes over 35%, even then just for a second while mousing over stuff.

[Avaton]

8400? Is that AMD?

Maybe it's a CPU thing then. All the machines I've tested this on are Intel.
