LR 3 is Unuseable

Question

Physical processor count: 4
Processor speed: 2.6 GHz
Built-in memory: 3070.5 MB
Real memory available to Lightroom: 716.8 MB
Real memory used by Lightroom: 1098.3 MB (153.2%)
Virtual memory used by Lightroom: 1217.0 MB
I can't even export a 1024x640 image after correcting the RAW version ... and while editing the RAW file I constantly hang with "Lightroom not responding" and efects taking very long to render.
I can't function like this.  There just has to be a problem here.
Recommended RAM is 2GB.....they obviously forgot to adress the issue that Vista has by not allocating required memory to the program as Vista manages memory and seems to only allocate less than a gig of RAM to lightroom.  There must be a patch they can put out that allows you th select how much memory you want to allocate to Lightroom.   My music editing and slide show software both have menu options that allow me to prioritize when in use and to take all available RAM while software is running.  I am sure Adobe can do the same.  They missed the ball here.
I must export each raw file into CS5 and then save the file from CS5.  Horrible.

Answer 1

Well I ran it bcdedit ... you can see the user value below.
identifier              {current}
device                  partition=C:
path                    \Windows\system32\winload.exe
description             Microsoft Windows Vista
locale                  en-US
inherit                 {bootloadersettings}
recoverysequence        {572bcd55-ffa7-11d9-aae2-0007e994107d}
recoveryenabled         Yes
osdevice                partition=C:
systemroot              \Windows
resumeobject            {f177ad70-9f30-11dc-9737-001e8c2a4769}
nx                      OptIn
increaseuserva          3072
C:\Windows\system32>
I re-booted system...... opened lightroom
Physical processor count: 4
Processor speed: 2.6 GHz
Built-in memory: 3070.5 MB
Real memory available to Lightroom: 1228.8 MB
Real memory used by Lightroom: 743.4 MB (60.5%)
Virtual memory used by Lightroom: 869.6 MB
Memory cache size: 0.0 MB
System DPI setting: 96 DPI
Running the command to increase the RAM value to 3072 gained me 500mb or half a gig more ram but still short of the two GB that forms the system requirements minimum.  I still can't fathom why Windows 32bit Vista caches so much memory!
When I ran photoshop before the bcdedit command, my system was making 2GB of ram available to it (CS5 extended).  Checking that now, I note that it made another half gig available to it.
So, could this theoretically be an software issue?  Remember, before setting the bcedit uservalue to 3GB, real memory avail to LR was less than a gig, while a full 2GB was available to CS5 Extended.  After running it, values increased by half a Gig to each.   This seems weird to me, where Windows allows the required RAM to CS5 but markedly limits it to LR.
The command by the way to reset the BCedit user value for anyone else trying this is :
C:\>bcdedit/deletevalue increaseuserva  
Remember.....always reboot system for changes to take effect.
In summary...........could there be a programming situation within LR that, for some reason, is limiting the allocation of memory?  I only make this assumption because no such problems exist with memory avail to CS5, even before I ran the bcedit changes.
Thanks
