Does turning off modules speed up Lightroom 4?

Hi All,
It seems that in Lightroom 4 you have the ability to turn off individual modules by right clicking on them and unchecking whichever ones you don't use.  I'm wondering if when modules are unchecked, does that increase the speed or performance of the system?
I recently upgraded to LR4 from 3 and definitely experienced a major slow down.  That being said, when I uncheck everything except the development module, the sluggishness completely disappears.  Is turning individual modules off actually helping performance? Can anyone else confirm this?  I've posted on a few other forums and haven't had a great response.  Thanks!

Actually, in another thread this topic came up and I'll post my results below...
The posts above are correct, simply "right clicking to turn off the modules from the title bar does not disable them.
I have had significant performance gains by actually removing the modules altogether from the Lightroom program folder.
Your mileage will vary.
My original posts come from this thread : http://gsfn.us/t/2qqr8
I've made slight edits for context.
When I removed the modules, I started from scratch.
I simply uninstalled LR4.3, defragged, reinstalled, updated, moved the modules i dont use, rebooted.
I then used this link for the How To : http://www.slrlounge.com/boost-lightroom-4-performance-by-hacking-the-lightroom-modules-li ghtroom-4-workflow-system-dvd
It's insanely easy.
I followed the standard Adobe recommendations for lightroom that you can search for in "help".
I started Lightroom with one of my (large) existing lcat files (11k images) and regenerated absolutely everything at 1:1.
Ate dinner, played the Xbox, ignored the phone... had family time for a while.
right now,
it opens bullet fast into library.
it's 10 seconds to move from library to develop. film strip scrolls bullet fast- but at super low Rez and takes 3 seconds to load the "highrez thumbs" - once I stop moving the strip (12 thumbs wide)
When an image is clicked they open to "fit" within 3 seconds. Choose 1:1 and its 5 seconds.
switch to library again and it's 1-2 seconds and a redraw of the image - filmstrip unchanged.
choose an image at 1:1 and its a 3 second wait
"Fit" is immediate. awesome
these times flex a second either way depending on image content.
scroll film strip and it behaves the same as above - but not jerky like it used to be (up till today's efforts).
LR4 is way faster than LR3 like this.
==============
--- I then read another person's post relating to my earlier posts and decided to do a test :
==============
put modules back.
20 seconds to start.
I don't change the image shown.
change to develop 30 seconds
5 seconds to "refresh" same image same setting of "fit"
change to 1:1 6 seconds
lower to fit 2 seconds
back to 1:1 2 seconds
film strip jerky on develop
thumbnail refresh same speed
change to library - 3 seconds
I'm still in 1:1
film strip "less jerky" - only a slight lag
3 seconds to load a new image as 1:1
1 second to change to "fit"
1 second back to 1:1
with the one main image chosen in library, mouse wheel scroll is pretty darned quick, low Rez "fit" with 1 second refresh when you finish moving
10 seconds to go back to develop in "fit"
5-6 seconds for subsequent photo choices in fit
1:1 is ten seconds
scrolling the 1:1 is so jerky you have to use the mouse "hand"
exit
move - book, layout, print, slideshow, web
delete win prefetch references for a clean start, reboot.
wait for windows to realize its a computer and settle down.
start Lightroom, same lcat.
it remembers I was in develop and reopened in 5 seconds with a "fit" image
cool actually - program loads and displays image all in 5 seconds, in develop.
change to 1:1 2 seconds
can actually scroll 1:1 with mouse only small lag
film strip back to new normal (fast and smooth)
change to library immediate
back to develop 1 second
new image 2 seconds on fit
1 second to 1:1
new image 1:1 2 seconds
so yeah
module disable worked for me
my pickle?
I have to test each one at a time to point adobe as to which is the issue...
*sigh*

    (I'm doing this for the recalibrating of the battery etc...)

    It would shorten it's life if you leave it on year 'round. For the amount of time to calibrate the battery won't hurt it.

  • Does turning off wireless feature inactivate the firewall?

    My goal is to insert a hardware firewall between my modem and PPC Mac computer, and accordingly, plan to use the Apple Airport Extreme (AE) base station router for this purpose.  Since I don't really need the wireless feature at this time, I plan to turn off Wi-fi on AE.  Will doing so also turn off or diminish the WPA/WPA2 & WEP security firewall features of AE, or will they still work as expected with my wired internet connection?

    Wireless security is not really referred to as a "firewall" in the strict sense of the word. Wireless security, or encryption, is used on your "local" network to prevent unauthorized computers from connecting to your local network.
    A firewall is special software that protects all devices on your local network from devices on the Internet.  The AirPort Extreme uses a very effective NAT firewall.
    If you have the AirPort Extreme connected to a simple modem, the NAT firewall is automatically enabled.

  • Does turning off iPod erase iPod diagnostic data

    When ever safari crashes I understand that it keeps that data and next time you connect it appears as diagnostic data. I always turn off/on my iPod touch when that happens. My question is that turning off iPod erase iPod diagnostic data? Is it necessary to turn off the iPod to stop crashing?

    I've not seen anything official but it is true in my limited experience that turning the iPod touch off does seem to clear that crash info. In my first two crashes I was offered to send info to Apple the iPod touch was connected to my iMac. In my latest two crahes I've turned the iPod off before connecting to iTunes and was not offered the chance to send info to Apple this time. Will continue to monitor.

  • Does turning off DHCP remove option to Share Hardisk over WAN?

    I'm a recent Apple convert. I have a new Macbook and have downloaded all recent updates.
    I just integrated the Airport Extreme Base Station into my current home network. I have DHCP turned OFF in the AP because I am running a netgear router in my basement that is already connected to my Cable Modem. It needs to stay in the loop because I am using it to feed my XBox360, due to the issues related the Base station/360 interaction.
    Here is my question... Does having DHCP turned off in the AP, remove the checkbox option in the "Disks" section of Airport Utility toolbar to "Share disks over Ethernet WAN port"? Its MISSING completely. I've seen many instructions that reference that phrase, but the only checkbox I have on that screen is one for using Bonjour. I want to connect a usb drive so I can have a central storage so my wife and I can share itunes/photos/documents. So could it be that option disappeared due to turning off DHCP or is there some other issue?

    If you want to share your disks over WAN then you need to do the following:
    1. Assign a manual IP address for your AirPort. You can do this by running AirPort Utility and under Internet you need to change Configure IPv4 from Using DHCP to Manually.
    2. You need to port forward TCP port 548 on your main router to the IP address you assigned your AirPort. After doing this you will be able to access your AirPort disks by going to Finder, Connect to Server, and entering afp://<yourgatewayipaddress> You can find your gateway IP address by going to www.whatismyipaddress.com while on your home network.

  • Does turning off email delivery also turn off text delivery?

    I just got an 8330 when my work switched to Sprint. I am on vacation for the next two weeks and would like to turn off my work email delivery. It comes through a Microsoft Exchange server. I also have two AOL personal accounts on the phone. If I select "No" for "send email to handheld," will that stop delivery of all my email accounts or will AOL messages still be received? I have separate icons for each of those accounts.
    In addition, I do not want to stop delivery of text messages. I have them separate from email right now. Will doing the above stop delivery of texts? 
    I looked to see if this had been answered before, but did not find it. Sorry if I missed it. Thanks for any help you can offer.

    HI and Welcome to the Forums!
    For your work emails, I suggest you talk to your BES admins about what to do...they are in control of that component.
    For the personal emails, the setting to NO will accomplish what you desire...it does exactly as it states (Send Email To HH = NO). You have to set that for each account.
    None of this affects Text Messaging...those are completely separate.

  • Does turning off debugging help a compiled .exe file run faster?

    I'm trying to get my application to run faster.  I saw on this website that turning off the debugger makes the application run faster but it's unclear if that applies to the development platform or a compiled executable.

    You are probably referring to this KB article: General Performance Improvements. When you create a stand-alone application you can also enable debugging. This will save the block diagrams so you can debug the application while it's running. Normally when you build an app the block diagrams is stripped.
    The amount of impact that turning off debugging will have to your VI/app performance is hard to say. To best way to get a VI/app to run faster is to improve the code in the first place. This means avoiding very large memory arrays, not initializing and closing references every time you iterate in a loop, minimizing file I/O, etc. If you provide some idea of what your code does, and can perhaps post your code, specific suggestions can be provided. 

  • Does turning off your MacBook by holding the power button hurt your MacBook

    Almost whenever I exit out of War Craft 3: The Frozen Throne my Mac Book freezes up, as a result I frequently turn off my Mac Book by holding down the power button- Does this hurt my Mac Book?

    There is most definitely a chance that you can cause stability problems (although, it is somewhat less likely that you would cause any harm to the hardware). The likelihood of you causing problems increases directly with how often you shut down this way. You should be seeking a solution to the issue you are having with WC3. As Johathan mentioned, OS X does quite a bit in it's shutdown process. Bypassing that can cause anything from basic data corruption, to stability issues, to a non-bootable system depending on what the machine is in the middle of doing when you force it to shut down. In general, worst case scenario is that you would need to re-install OS X to fix things up. It's really not worth taking a chance on your systems stability for the sake of a game. I would say that you really should try to track down a solution to the problem you are having with the game.

  • Does turning off iCloud backup delete backup

    I am thinking of making a monthly backup of my devices in iCloud as I still prefer (sorry) to use iTunes on my PC. The idea is to have the previous  months backup available in iCloud should any problem occur.
    If I backup to iCloud and then revert to backing up using itunes on my PC between iCloud backups does this delete the iCloud backup after a certain time period?
    Thanks

    turning off iCloud  wouldn't affect any of your locally stored documents. Just turn the feature off by opening System Preferences > iCloud.
    Oh OK. The message was confusing me: http://i.imgur.com/kZOu5zr.png ... It sounded like disabling iCloud would delete my Mac's local copies.

  • Does turning off 3G really help call reception/signal strength ?

    After experiencing more of the S.O.S. with the 2.1 upgrade I turned 3G off today.
    It's really ******* me off that I am paying another $15 - $20 a month for something that seems useless and problematic (And now just to turn it off).
    Does this really help with the issue pertaining to dropped calls ?

    Hi guys
    Hope you don't mind me dropping in, but I work in the telco industry, albeit in Australia. The turning off of 3G for better reception isn't an iPhone fault, it's a network thing.
    Any phone with 3G capability is programmed to try and access the 3G side of the network first. It will continue to scan the network all day and night, anytime your phone is on to maintain signal. If it's unable to maintain service coverage with 3G, it then drops down to 2.5G, then 2G, then EDGE (if available in your area). If you turn 3G access off, it skips that step. The older networks are more reliable, but slower. They are also (now) much less crowded with users so there is less congestion and you get (on occasions) better signal.
    The recent 2.1 upgrade would have modified the supply of power from the chipsets to the antenna's which is why many people are experiencing better signal strength and less dropouts, but it will always come back to the 3G coverage in your area.
    I know this doesn't really improve things for you, but gives you some background to how the whole circus works.
    Cheers

  • Does turning off iCloud backup affect my photostream, contacts, and calendar wireless syncing?

    I keep getting the announcement that my icloud storage is almost full, so I checked into managing my storage. If I turn off the "Storage and Backup" on the bottom, will that affect my contacts, calendars, reminders, and photostream wireless syncing? I don't want to pay to get more icloud storage.

    No, that just means it will no longer backup your device to iCloud.
    More than likely it's the amount of photos and videos in your camera roll taking up all that space, hence why your storage is almost full. You can manually backup these photos and videos to your computer and then turn off the backup for just the camera roll (you'll see this option under Settings, iCloud, Storage & Backup, "This iPhone" or device you have, and then you can toggle Camera Roll on/off, where it also tells you how big the camera roll is) and still continue to backup the rest of the device (Settings, apps, wallpaper, etc) to iCloud. Or just turn the whole option off and backup to iTunes instead.

  • Does turning off WiFi stop 3GS battery drain?

    Hi All
    This question is NOT directed at those who can't make phone calls for more than 5/10 mins (although I was once that man).
    I have had problems with waking up in the morning to a randomly dead iPhone, even though battery was at least at 50% before going to bed. However, whenever I turn off WiFi before going to bed I wake up to my iPhone only having lost around 10% battery.
    So, my question is, could people with the same problem as me please try turning off their iPhone's WiFi before going to bed and see what happens?
    I would be interested in the results.
    Thanks
    PS. Please no 'Have you tried...' posts as the answer is 'Yes, I have!'

    Hi BigBex,
    My wife is currently using my iphone and in the last couple of weeks, I have noticed that when ever I go to use it, the battery is very low.
    This phone sits in her handbag most of the time not being used, but the battery was still 80% down within the day.
    I turned off WiFi a few days ago and the battery seems to settled have down and has only used about 25% per day.
    I intend to have a much closer look over the next weekend to see if I can determine what may be causing the drain.

  • HT4515 Does turning off group texting prevent my replies from going out to the mass?

    I receive responses to group texts. How can i assure my responses do go to everyone else as well? Just turn off group texting?

    Hi Auntie_Em4!
    I have an article for you here that can hopefully help you understand group messaging a little further:
    iOS: Understanding group messaging
    http://support.apple.com/kb/HT5760
    Specifically, I believe this section of that article answers your question:
    If you send a message to multiple recipients without group messaging in use by the sender and all recipients, an individual message will go to each recipient using either SMS or MMS. Responses to these messages will be delivered only to the original sender in seperate messaging threads.
    Take care, and thanks for visiting the Apple Support Communities.
