Lightroom 2.0 Develop Control Speed Issue?

Hi, just upgraded from Lightroom 1.4.1 to Lightroom 2.0.
First off, a big hats off to the fantastic talents at Adobe for putting out a pretty great release with some killer features. I am really enjoying the update---particularly the awesome camera profile feature----now my reds and oranges from my Canon DSLR are exactly as I expected them to be.
Now a problem I seem to be noticing (before commenting please check below the problem text to see my setup and also the things I have already done to resolve the issue):
The Problem:
I notice that when I am in the Develop module and manipulating the controls to do my edits that compared to version 1.4.1 the controls seem to be a good deal less smooth (in that I mean it is a good deal more difficult to get nice smooth fine controls---rather it seems jumpy and moves in coarser increments). This just might be my mind, but when I enable a second monitor the controls seem to be even more jumpy or less smooth).
To make sure I wasn't imagining things I opened up another catalog of images in version 1.4.1 (a catalog that hadn't yet been converted over to the new 2.0 version) and carried out the same edit. In version 1.4.1 the controls were extremely smooth and moved so finely that I was able to get 1 digit changes very easily with my mouse.
What I have already done to resolve this problem:
1. I have properly updated my catalog to the 2.0 version.
2. I have optimized and restarted the catalog.
3. I have made sure that auto write to XMP was NOT enabled.
My system (fairly new and fairly powerful):
--Macbook Pro 2.5 Core 2 Duo Penryn
--4 GB of RAM
--Catalog on fast RAID drive setup for 0 connected via Firewire 800 (same as before the lightroom update)
--Free space on Macbook Pro is about 150GB
--512 GeForce 8600M GT Nvidia card
The Questions:
Is anyone else having this problem? Also does anyone think this might have anything to do with recent news about 8600M GT cards going bad---perhaps Lightroom 2.0 takes advantage of the GPU more so than 1.4.1 did? If Lightroom 2.0 is indeed taking advantage of the graphics card more than 1.4.1 does anyone think that 2.0 might over working the graphics card and therefore allowing the card's flaw to show through in jittery UI controls?
Other thoughts?
Thanks in advance for people replying to this post.

I also have a problem with the adjustment brush. Very slow and jerky to use, almost useless with larger brush. If I try to adjust the slider once an area is selected it can take >4s to update and if a bit hesitant in moving the slider each tiny movement gets interpreted as a new command and the display gets updated every 4s until it runs out of commands in the buffer. Also I get the problem with the sliders remaining coupled to the cursor even when it is somewhere else entirely. At first I thought it was operating like the curve region sliders but something else is happening.

Lightroom 2015 cc Develop module Display issue

I have just upgraded to Lightroom 2015 cc.
When I go into the develop module, it will not display the image, I just get a solid blue image.
I can see the image in the navigator panel and if I go full screen, plus you can see it in the library module.
I have tried creating a new catalog, but the same thing happens again

Question about HSL Develop Controls vs. Photoshop Selective Color

Im an advanced Photoshop user and I enjoy shooting landscapes, macros and abstracts. Ive just started to experiment with Lightroom and have used it to process several hundred shots from a recent trip to the California Coast.
Even though my usage of the next Develop controls in Lightroom is still pretty limited, I find the new Basic Develop and Tone Controls to be very intuitive to use and Im getting better results than I could from Adobe Camera Raw 3.7 and earlier. Therefore, kudos to the Lightroom team.
But, I also have some questions regarding the HSL controls and what seems to be an omission of some useful functionality. To help with framing my question lets assume that we have shot of a waterfall in the forest. The waterfall is in partial shade and the rest of the scene is in partial to full sun. Also the histogram for image indicates that a blend of several bracketed images isnt needed to deal with the overall dynamic range within the scene.
If I was processing this shot in Photoshop, I would likely adjust the overall White Balance / Exposure / Black Clip / Contrast / Brightness in Camera Raw and then finish the image within Photoshop. Since the water of the waterfall described above is in the shade, it will likely have a color cast relative to the White Balance that I set for the rest of the image that is full sun.
With Photoshop, I would often set a couple of sample points and then use a Selective Color layer to correct for the color cast in the whites of the water and to neutralize the blacks in the shade. I would also sometimes increase the amount of black in the Selective Color Blacks tab to enhance the image contrast. These adjustments could have layer masks associated with them but for this example lets assume that the dont need any mask. Thus, I would hope that I could accomplish the same type of globally based whites and blacks color cast removal within Lightroom but I cant seem to find a way to accomplish this.
With Lightroom, I see that there are a set of HSL controls that should be able to handle much of what Selective Color could handle on a global level within Photoshop but I dont see any controls to deal with the Whites or Blacks. Am I missing something? Is there a way to accomplish the type of correction that I described above with Lightroom or am I going to have to take the image out to Photoshop and use Curves and/or Selective Color?
Dave

Fred, Richard - Thanks for responding.
I've tried the TAT tool but it only controls the colors controlled by the sliders in the HSL palette. Therefore, it doesn't seem to have any affect on the hue of the whites or blacks in a picture.
Regarding selective editing, I realize the the controls within Lightroom are global but unless I use a Layer Mask the Selective Color functionality within Photoshop is also global. That is, if I change the hue of the blacks then all blacks are affected. Hence, it seems to me that the HSL controls within Lightroom and the CYMK controls within Selective color can be used to do much the same thing. The big difference is that the Selective Color control set include the ability to adjust blacks and whites but this isn't included within Lightroom.
I also posted my message in the ACR forum as ACR 4.0 is going to include the same set of controls that the Develop module in Lightroom contains. Someone there suggested that I might be able to use the split toning controls to warm up the shadows and I will give this a try. I also plan to post in the Feature Requests Forum.
Thanks again for your help.

Another Yosemite speed issue

This is yet another Yosemite speed issue. I've done some reading around and read the FileVault can cause an issues, I took a look and I've always have FileVault disabled. I installed EtreCheck and the results came up with a lot of RED and "FAILED". Unfortunately, I have no clue how to being to read this and was hoping someone could shed some light onto this for me.
Here are my results: (Just trying to right-click and paste this took almost a minute)
Problem description:
Installed OS X Yosemite and now Macbook runs extremely slow. I have had FileVault disabled the entire time.

Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
    1. AppZapper
    2. AppDelete
    3. Automaton
    4. Hazel
    5. AppCleaner
    6. CleanApp
    7. iTrash
    8. Amnesia
    9. Uninstaller
10. Spring Cleaning

Speed issue: renaming exposed VO in AM data model page

Hi JDev team
I'm having some speed issues with a refactoring option in JDev 11gTP4.
If I open the AM editor, navigate to the data model page, select an exposed VO, then rename it via the View Instance edit button dialog, it takes 1min 25seconds to complete the operation, locking the IDE meanwhile. It (subjectively) feels really disruptive when you're rapidly developing to have to wait this long.
Is this an issue that's been identified and logged as a bug/issue?
Cheers,
CM.

Chris,
as a regional directory you should have access to Drop 6 meanwhile (or any day soon). Can you verify the issue against that build ?

Speed Issue in Report With 1130680 Records Returned

Hi
<b>Apologies to the mods if this is in the wrong section, it contains content related to Legacy SDKs (VB6/COM), newer .NET content as well as report design issue.</b>
I'm using Windows XP SP3 with the database hosted on my machine, an [email protected] with 2GB DDR2 RAM. Neither the client's pc nor their server are as powerful as mine. (It sucks, I know.)
A report has a speed issue for the end users. The query to the database (SQLS2008) takes 30 seconds and returns 1 130 680 records. And yes, this is the amount of records that need to be returned (the report is a Sales Details report for transactions from 2008/09/01 to 2009/03/31) Running the query through SQLSMS takes the same amount of time whether I execute the statement that the report sends or put the query into a stored procedure. The relevant indices are in place.
Our application is written in VB6 and uses the CR9 unmanaged runtime. I've written a small little CR application in VS2008 to see if running the report through the CR.NET runtime would make it quicker. I built the .NET app in release mode (with optimization and no debug data) and ran the exe to do the speed tests. The times taken for the report to run:<ul>
<li>VB6 app - 3:30s
<li>.NET app - 4:30s
<li>VS2008 IDE - 2:02s
</ul>
I have run the report three times for each app using my cellphone as a stopwatch and the times are reproducible to within two seconds.
I accidentally ran the report in the VS2008 IDE and it took 2:02s to run. Thinking that the loading of the DLLs in .NET was part of the problem, I added code under a button on the form with the following code:
CrystalReportsApplication1.Properties.Settings a = new CrystalReportsApplication1.Properties.Settings();
Assembly aAss = Assembly.LoadFile(a.CR01Engine);
Assembly bAss = Assembly.LoadFile(a.CR02EntFramework);
Assembly cAss = Assembly.LoadFile(a.CR03EntInfoStore);
Assembly dAss = Assembly.LoadFile(a.CR04ReportSource);
Assembly eAss = Assembly.LoadFile(a.CR05Shared);
Assembly fAss = Assembly.LoadFile(a.CR06WinForm);
to preload the assemblies. Unfortunately it made virtually no difference to the running time of the report.
Suggestion from The specified item was not found. on [this page|Speed issue - internal processing vs views;:
8. For summaries, use conditional formulas instead of running totals when possible.
I didn't know that, but we're doing that already.
I even tried using ngen in a virtual machine for the .NET app, but the time was the same. And yes, I know that ngen is only supposed to aid startup times and that it is actually recommended to let the JIT optimize on the fly instead of ngen optimize beforehand. What really struck me was that even in a VM (using Virtual PC 2007) using 512MB of RAM and only a single core the time was the same.
My questions:<ol>
<li>I thought that VS2008 shipped with CR2008 Basic, but according the the references in my project it's CR10. Would the CR2008 runtimes improve the report speed?
<li>Why do the CR10 .NET runtimes take longer to execute than the CR9 COM runtimes?
<li>I really, really, really need the .NET runtime to outperform the COM runtimes as our purchase of CR2008 hinges on this. As you can probably guess, we're currently using ye olde CR9.2 from 2002.
<li>Why oh why do the CR10 .NET runtimes take longer to execute than the CR9 COM runtimes?
<li>The first level of grouping is a variable which changed the grouping depending on a parameter. I changed it to a field from one of the tables and the times for the apps are:
<ul>
<li>VB6 - 2:15s
<li>.NET - 2:48s
<li>CR9.2 IDE - 2:19s
<li>VS2008 IDE - 2:34s
</ul>I may or may not be able to push it out to the client like this, I don't know. Why did the VS2008 IDE take longer this time? All I did was change the grouping-on-parameter to ordinary grouping.
<li>Why oh why oh WHY do the CR10 .NET runtimes take longer to execute than the CR9 COM runtimes? Are they just thunkers to the COM DLLs?
<li>Why does the run in the VS2008 IDE (in debug mode BTW, not release mode) run quicker than both programs?

Thank you and have a blessed Easter!
Edited by: AndrewJ on Apr 14, 2009 10:04 AM. Changed the CPU, I was thinking of my CPU at home.

Please re-post if this is still an issue to the .NET Development - Crystal Reports Forum or purchase a case and have a dedicated support engineer work with you directly.
Bottom line is CR Basic is version 10.5. CR 2008 is 12.2.x.xxxx. Install CR 2008 SP 1 to get .NET support.
And you can't compare COM to .NET, it's like comparing apples and oranges, both fruits but different flavors.

WRT54G ver 7 speed issues.

Hi all.
Let me go through the issue I have come across tonight. I have a WRT54G version 7 cable router, and I have Telewest as my ISP, with the 4Mb service. My computer is hard wired into the router, and have no wireless clients connected at the time. I get packet loss, (quite a bit) and my download speeds are abismal. Setting my computer to dhcp or fixed IP makes no difference. I even forced 100 Full duplex on the LAN card just to be sure. I phoned up TW tech support, and they were pretty helpful, and asked me to bypass the router, and plug directly into the modem and turn dhcp on my pc and reboot the modem.
All works fine, no speed issues, download test from here is perfect. They asked me to download something off their server here http://gamefiles.blueyonder.co.uk and I am getting full 480kB/s And here is the test plugged right into the modem http://www.thinkbroadband.com/speedtest/results/id/117018476054017621619.html
Happy days, right? Problem with the router, right?
Well.. It gets interesting.
I then do a firmware update on the router, reset it to factory defaults, and re-run the test going through the router. Here is the pitiful result., which is the same as before. http://www.thinkbroadband.com/speedtest/results/id/117018491367303621734.html
Ok... so problem with the router still... right?
I tried the blueyonder file download, and guess what... 480KB/s again, downloaded a 5 meg file in about 12 seconds.
What I have tried:
Forcing the LAN to 100Meg full duplex
Firmware upgrade on the router
Reset router to factory defaults
Rebooted pc, router and modem at the same time.
Use a static IP with correct settings (same speed)
Use DHCP through the router
Connected directly to the cable modem and use DHCP (works fine)
PC windows xp SP2 fully patched.
No software firewalls. (at any time)
Disabling UPNP on the router
Turned flow control off on the LAN adapter (shouldnt be on in the first place, thats half duplex >.)
I cant see why my computer downloads from blueyonder fine with no speed issues at all, and yet any other website, I get extremely poor performance. This router has been working fine for about a month now, just needed a few reboots once in a while, but which router doesnt. My upload speeds seem pretty constant, and dont seem to vary regardless of router or not. Seems like inbound traffic is getting jammed.
Anyone able to shed some thought? Sorry for the wall of text, just thought I would let you know everything on the first post instead of having to reply a dozen times.

try TCP Optimiser .. This should adjust the MTU settings of the NIC on the PC ...

Control record issue !

Hi All,
I am handling UK Payroll and got an issues related to payroll run and control record,
Issue 1: The payroll driver (RPCALCG0) has skipped around 1500 Employees against payroll run for particular period
Issue 2: How control record allowed user to Exit control record for period in which EE's skipped in payroll
Please provide your valuable suggesting in regard to resolve the above two issues,
Thanks in advance.
Regards,
Devendra Reddy D.

Hi,
Issue 1: The payroll driver (RPCALCG0) has skipped around 1500 Employees against payroll run for particular period
Say you want to run payroll for FEB..
But payroll control record may not be in FEB... It may be in March..
Issue 2: How control record allowed user to Exit control record for period in which EE's skipped in payroll
Payroll control record may have been deleted on the month of Jan..& been set in Release mode in March month directly...
So feb month gets skipped & Exit mode in Feb is skipped too...
For detailed info.. Go to PA03 enter payroll ares & click display option..
Under Go To tab.. look for Control Record Log..
Regards,
Veeram

Speed Issues

Greetings and Salutations,
I'm having speed issues with my Adobe AIR application. From what I've read on the web, AIR is supposed to be fast at drawing graphics. I am writing an application which has multiple screens. On one of the screens I have a tab (SuperNavigator) which has a canvas on it. That canvas has a series of other canvases (built with a repeater) that have graphics in them. I am having speed issues when I have more than 50 of these children canvases. I've tried running it without the graphics (code below is without the graphics) to see how it performs. When I have 954 of these canvases being drawn it takes about 2.5 minutes to draw. This is unacceptable and I'm wondering if this is something I've induced or if AIR was never meant to handle such a large amount of canvases (actually this isn't a large amount, in a real world environment there could be a lot more). I've included relevant clips from the code. There are a couple empty boxes that in the real application will hold graphics.
The class withing the Tab Navigator is a canvas.
In the action Script (the setter line takes 2.5 minutes to get past) (it's binding to the repeater that seems to be my problem).

I would appreciate any thoughts or feedback you could provide.

The Canvas is a very heavy object that has lots of overhead. Even worse is the VBox object that is in there multiple times.
What exactally are you trying to accomplish? Just looking over the code, it seems that the same could be done directly with the Graphics API, at a much faster rate.
For each of the VBoxes and Canvases you have, the entire size of each child and parent need to be re-evalulated each time you add or change something. This is a HUGE overhead, and probably why the app is running so slow. You may need to convert this app to use simpler objects (UIComponent or something lower-level like that) to get any speed.
Are you using Flex Bulder? Take a look at the app while the Profiler is running to see what I'm talking about.

Speed Issues Fixed In 9.1.2

Lost all my thumbnails updating to iPhoto 9.1.2 but rebuilding the thumbnail database solved the problem. Best of all, the speed issues are finally gone in iPhoto 9.1.2. Opening the application is way faster again (2 seconds as opposed to 12 seconds or more). Scrolling is way faster again. Can't believe it took this long for Apple to fix this mess. Nevertheless, iPhoto '11 feels like iPhoto '09 once again. Thanks Apple.

Iteration Speed issue when Indexing 3D array wried to a while-loop

Brief Description of my Program:
I am working on the real-time signal generation by using LabView and DAQmx (PCI-6110 card). My vi reads the big data file (typically 8MB txt file containing about 400,000 samples (complex double precision). Then, the signal is pre-processed and I end up with a huge 3D array to feed while-loop (typically 3D array dimension is N x 7 x M where N & M >> 7). Inside the loop, that 3D array is indexed and processed before the results are written to the DAQmx outputs. I have a speed issue when indexing the large 3D array (i.e, 3D array having a large sub-array size). My while-loop could not run fast enough to top-up the DAQmx AO buffer (at the output rate of 96kHz). It could run faster only if I use smaller 3D array (i.e, smaller-sized sub-arrays). I do not quite understand why the size of 3D sub-array affects the rate of looping although I am indexing same sub-array size at each iteration. I really appreciate your comments, advices and helps.
I include my 3D array format as a picture below.
Question on LabView:
How does indexing an 3D array which wires to the while-loop affect the speed of the loop iteration? I found that large dimension of sub-arrays in the 3D array slows down the iteration speed by comparing to indexing the same size of sub-array from smaller-sized sub-arrays of the 3D array to perform signal processing inside the while-loop. Why? Is there any other way of designing LabView Program to improve speed of iteration?
attachment:

Thank you all for your prompt replies and your interests. I am sorry about my attachment. But, I have now attached a jpg format image file as you suggested.
I had read the few papers on large data handling such as "LabVIEW Performance and Memory Management". Thus, I had already tried to avoid making unnecessary copies of data and growing arrays in my while-loop. I am not an expert on LabView, so I am not sure if the issues I have are just LabView fundamental limitations or there are any other ways to improve the iteration speed without reducing the input file size and DAQ output rate.
As you request, I also attach my top-level vi showing essential sections such as while-loop and its indexing. The attached file is as an image jpg format because the actual vi including Sub-VIs are as big as 3MB in total. I hope my attachment would be useful for anyone who would like to reply my question. If anyone would like to see my whole vi & llb files, I would be interesting to send it to you by an e-mail privately and thus please provide your e-mail address.
The dimension of my 3D array is N x 7 x M (Page x Row x Column), where N represents number of pages in 3D array, and M represents the size of 1D array. The file I am currently using forms 3D array of N = 28, & M = 10,731. Refering to the top-level vi picture I attached, my while-loop indexes each page per iteration and wrap-around. The sub-VI called "channel" inside the while-loop will further index its input (2D array) into seven of 1D arrays for other signal processsing. The output from that "channel" sub-VI is the superposition of those seven arrays. I hope my explaination is clear.

Home Hub 3 Speed Issue

Some 6 weeks ago I had an issue with losing my internet connection completly, and eventually after a long session with the help desk I magaged to reconnect using the direct port on the main phone socket. However since then I have had a speed issue and Ive been only getting speeds in the order of 2.3Mb.
However running the BT speed test tells me that the connection to my Home Hub 3 is running at 8.13Mb, but the connection to my computer is running at 2.18Mb.
I have tried every thing I can think of. Followed all the advice to improve the connection but nothing works. Reseting the Home Hub, reseting the factory defaults. I've closed down every program running in the background, disconnected the rest of the hardwired network, fitted a new shorter cat 6 cable. All to no avail. The speed still stays firmly at 2.18 to 2.15. down and 0.37 up.
Could their be a fault with my Home Hub?
Thaks for any advice.
Roy

Windows 7 64bit speed issues

Hi,
Our company have been purchasing iMacs for the past 4-5 years and installing Windows XP without any problems. Last year we started installing Windows 7 64 bit onto, the then current, leopard model without any issues.
We have recently purchased a whole batch of i5 iMacs with lion installed. I have installed Windows 7 64 bit without any problems but have started noticing huge slowdown with what seems to be hard drive access o every single machine. Even a single one we purchased when they first came out.
Using Perfmon I cant see any stress on the CPU, GFX card or RAM but there seems to be something odd with the hard drive access. I have stripped Windows 7 down to its bare minimum services removing Aero, themes, and all non essential services but still the speed issues occur.
I have messed around with the pagefile size, indexing, etc, but nothing is having any impact.
For example, when I save a simple spreadsheet the saving window appears in Windows 7 with the spinning circle for around 30 seconds. This is a tiny file, why is it taking so long. Its virtually instant if done on a Windows XP bootcamp machine or even in Windows 7 on an older Leopard iMac.
There really isnt a great deal regarding this problem oin the internet but it has occurred on all the new i5 Lion iMacs we have.
Does anyone have any other suggestions (serious ones ) that I could try?
I am currently installing the 32 bit version to see if it is a driver issue.
Cheers

isn't apple now using propritary drive firmware in 2011 imac?
I suspect 30 sec is drive delay spinup and is frequently happens with green drives, I have some and do this. swap for WD black or something.

Question?
I have accidentally deleted a large number of develped images in Lightroom before I did a backup. I reimported the original raw files back into Lightroom hoping the develop settings would be re-established but no luck. Notice system mau have done an auto-backup as have an lrcat-journal file. Can I use this to restore my develop settings. I also have jpgs generated from all the deleted images.

Hello,
if you have a backup of your catalog you can do the following:
1. Backup your catalog first
2. Restore your backup catalog to some location
3. Open your current catalog and select "files->import from another catalog".
4. Select your backup catalog and your lost images. LR ask you if you want to overwrite the current settings or save them as a virtual copy.
As an alternativ you can open your backup catalog, select the "lost" images and save the development settings as xmp sidecar fiels (using ctrl-s). Then open your current catalog, seletct the images and use "Metadata->Read Metadata from files".

Facing speed issue in my iphone 4, 16gb

Hi Guys
I am facing speed issue in my iphone 4, 16gb. may after updating ios 7, currenly i am using 7.0.4 update.
please help me if anyone have soltion.
Regards
Parveen

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.
The iPhone4 runs iOS7 without any issues or performance problems.
Apple does not provide a method to downgrade the iOS on any iDevice. Discussion of such matters in these forums is against the terms of use.
