Hi there,

I do a lot of research work so frequently have multiple IE7 open with
multiple tabs open in each, after a certain while if I try opening a new tab
all I get is a blank screen and the page will not load till I close some tabs.

Also it will not allow me to open any new windows till I have closed some.


So my question is what is the maximum number of tabs that IE 7 can have open
before it starts acting up?

thanks.

Simon

Well I've had 40 at one time....just out of curiosity....

thanks, I alsojust did a quick test,

I had 37 tabs in total, spaced out within 8 IE7, and it wouldnt let me open
up any more tabs or even open my computer.


That is a bit rubbish if you ask me.

Hi Simon:

The number of open tabs, as well as the number of open windows (browser or
otherwise), that provide full functionality without incident under Windows is
partially system-dependent. The closer a system is pushed to its capacity,
the greater the chance that something will go wrong.

Therefore, even if an absolute upper limit on the number of tabs in Internet
Explorer 7 exists, the actual "limit" will vary from system to system based
on resources and current operations.

I did not conduct tests, but I have over 20 years' experience with Windows
on 100+ systems. (I currently own 17 PCs.) I consistently find that some
systems are more reliable -- especially when pushing the envelope.

If I were to actually need 40 web pages open simultaneously (i.e., for
reasons other than convenience), and I could not tolerate any issues on that
particular project, then I would start linking multiple computers together
and consider using two connections to the Internet. Otherwise, I would
sacrifice some convenience and use the Favorites feature, desktop shortcuts,
and .MHT files on flash drives to organize my work and reduce the number of
simultaneous tabs and windows.

I have a very specific need that requires simultaneous and separate IE windows. I have routinely been able to open 40 at once on a single 'normal' computer without much trouble before IE crashes and all windows freezes. For this reason I have been forced to use 20-30 computers each with 40 windows in order to set up what I need. I have recently noticed that computers networked to a Windows Server platform have a higher limit and it seems to be unrelated to the hardware resources - at least on the surface. I have also read elsewhere that there is a GDI limit to the use of the systems resources which determines how many IE windows can be opened at once before windows blocks further allocation of any hardware resources. If anyone is familiar with this limit and how to override it in windows server, how could I find out if it would be doable to purchase a heafty workstation or server, run Windows Server OS on it and be able to open several 100's of IE7 windows on the same desktop? I understand this is a pretty specific request - I just don't know who to turn to and I'd rather not invest $5K in a system until I have a better game plan. Thanks in advance for any advice.

That's only one of several resource limits. Try using this tool to gain more
insight on your resource usage.

Actually not specific enough. You could at least be looking at
Task Manager's statistics with such extreme requirements to see
which ones are peaking when your problem symptom occurs.
PerfMon would be another tool to use to do related analysis.


Good luck

The maximum no of blank tabs that can be opened is 50 for IE7... and the
number of usable tabs will be propoional to the ram and processor present in
the system and inversely propotional to the no: of
spywares,viruses,trojans,applications installed on your system.

Nope - just opened 53.

Maybe you are lucky...

I had the same frustrating problems since 2001 til I found the solution
shortly ! You can extend "Windows´s most important memory", called
Desktop-Heap (remember this well !), via "regedit". After this you can open
at least > 150 tabs or > 52 Windows explorers or 1000 text-files with 1
Million digits in each in UltraEdit. The multitasking capabilities increase
enormously. You can open much more programs simultaneously without any
problems or crashes.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session
Manager\SubSystems]

"Windows" - rightclick - long text appears like:

%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows
SharedSection=1024,3072,512 Windows=On SubSystemType=Windows
ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3
ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=Off
MaxRequestThreads=16


This number "3072" is the Desktop-Heap memory !!!!!!!!!

Increase it manually: e.g. to 10240 having 4GB (3,4) RAM on XP !

%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows
SharedSection=1024,10240,512 Windows=On SubSystemType=Windows
ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3
ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=Off
MaxRequestThreads=16

Restart your PC and enjoy Windows real power capabilities !


In my eyes this is the most important tweak/trick in Windows of all, as no
increase of RAM or a newer CPU/hardware/software helps until this setting is
carried out !

In the name of all paying Windows users I please Microsoft to maximize this
memory as a standard in all future updates, upgrades, versions, systems ! My
synapse-system is to weak to understand why this for all users (consumers and
companies) most important and most genious tweak is kept secret so much.
Something important like this has to be written on the front side of each
Windows product cover of Retail Box, SB, OEM packing...).


It surely is not enough to write about this in a hidden place like
http://support.microsoft.com/kb/184802/en-us. It takes years to find it here.

We should all try to help each other as good as we can !

You might also want to search around and read up why messing with this
setting might not always be a good idea. For instance,
http://www.techarp.com/showarticle.a...tno=238&pgno=1 and
http://blogs.msdn.com/ntdebugging/ar...-overview.aspx

Basically, there is a fixed 48MB of system buffer memory for all desktops in
XP. If you increase the desktop heap value, you reduce the number of users
who can be logged into XP at one time (via the Fast User Switching, or a MS
virtual desktop manager, running applications as other users, etc), and also
risk problems due to XP having a lot of fonts and/or printers installed
(printer drivers and fonts also share this same system buffer). And
screensavers and the user login run as a separate desktop too. And if you
blindly set it to too high you'll prevent XP from being able to boot at all;
I've seen posts from people who've set it to 65536, or 64MB, without reading
up on why most people recommend no more than 12MB, and then complained
because XP won't boot up any more.

Yes, it can be a good idea to change this value, so long as you take into
consideration the penalties for doing so. No, I don't think it should be put
on a sticker on the Windows retail box - the majority of users should never
go near the registry editor, let alone risk trying to change this value,
there's too much potential for them to mess up Windows entirely. (There are
people I've had to provide support for that I'd be loathe to let near a
calculator, let alone a PC!).
