Lightrrom 2.1 slow - then fast - what the?

LR 2.1 driving me crazy - grads so slow So searched online and saw mixed response to 2.1 in regard the grad and brush tools.
Shortly after lr crashes. When I come back to it, the grads are MUCH faster. Previously about half a second (to update position, rotation, sliders) = virtually unusable. Now about tenth of a second between refreshes = usable. Refresh of everything has improved (although the eg exposure slider is still slow to refresh - about fith of a second).
Is this a memory issue? (I have 4gb RAM) It feels like trying to use photoshop on a 486!

Hi Viyacheslav
I think it's perhaps too much trouble for us both for me to try and share the container -- my managers would want assurances about copyright (the data is part of a previously published dictionary), and I'd have to build a smaller one as the current file is > 500MB. But thanks for your interest.
My container setup is pretty simple. It's around 45000 small XML files added to a node container for a read only database (no environment). I have 16 indices supporting a range of different searches and a couple of reports, and the only index relevant to the @lastModifiedDate search is the node-attribute-substring-string index mentioned above (when I tried other edge or equality indexes I deleted the substring index). The query script I intended would be instantiated purely to run the one query and then die each time, so I don't see there being any chance of getting past an initial slow query if that's the behaviour. Because that first query finds around 37000 matches among the 45000 dates, it's understandable that it would take a while but I'm not sure why it speeds up in the shell from the second time round. An obvious suggestion would be that some form of optimisation is taking place in the shell, but I don't understand the workings of DBXML well enough to guess how. Even if this is the case, knowing that it happens wouldn't help me speed up my query due to the life cycle of the script.
Perhaps I should just generate these stats on a daily basis rather than generating them on-demand, or else try a different approach at getting the counts. But thanks again for the comments.

Is the Core i7 processor comparable, much slower, or faster than the 2.8 Ghz core 2 duo from 2009?

I am looking to get a new MacBook Air, but when looking at the prices I am seeing the MacBook Pro 13" for the same price and a lot more guts (RAM and Processor). I am ok with spending the amount of money on the air if it means I get a computer that is like my iPad, which i love (flash based, snappy), but don't want it to be super slow.
I am coming off of a 17" 2.8Ghz MacBook Pro from 2009. I was happy with the speed and power of that machine. The most taxing thing I did was make a complilation of family movies in iMovie and burned them with iDVD once in the 2 years of ownership.
I mostly browse the internet and compose written documents, and keynote presentations.
I know my questions may seem stupid, but I don't know how significant the changes between i7 and Core 2 Duo are, so I ask the question:
I am wondering if the processing power in the core i7 will be somewhat comparable, much slower, or faster than the 2.8 Ghz Core 2 Duo I had in my 2009 computer?
Thanks for any help!!

Hi brosephb,
Like you I went through a similar comparison process. I bought the MacBook air 13" and up specced the processor and memory. I don't do anything taxing enough or frequently enough to NEED the extra power of the MacBook pro.
I am overjoyed at my air. It's gorgeous, the way it wakes instantly, it's speed and it's portableness is so endearing that I just don't use my iPad anymore. I read numerous reviews on it and the overwhelming opinion was it's addictive ease of use because of it's slim, light and rapid waking. At work I can hold the air with one hand, open it rapidly at will. It's just great but it's made my iPad redundant (for me anyway).
I see the new airs are even faster and I'm tempted to consider selling my 6 month old air and getting the new one, but, it runs a dream so I am happy to just be envious of the new one.
In short, unless you need the power (for your work) go for the air. I'm looking at a new iMac to use as a home work station. For the price of a new air I can get an iMac that will swallow any task for a good few years to come. And my air will suffice as my mobile companion. However, that's just me spoiling myself as, at the moment, I have no teal need for another mac. I may get the cinema display for any long winded tasks, as the screen size will help with multiple tasking.
A bit of a ramble, hope this is useful.

Slow, then fast execution of same query

I have a test query:
dbxml> query 'count(collection()/Quots/QuotVerificationInstance/@lastModifiedDate[.="2009-09-07"])'
With this index:
Index: node-attribute-substring-string for node {}:lastModifiedDate
The first time I run the query in the shell, it takes a while:
Query - Finished query execution, time taken = 29656ms
The second time I run the query, it's a more acceptable speed:
Query - Finished query execution, time taken = 735ms
Can anyone explain the difference in search speed? The slow, fast pattern is pretty consistent (I've tried fresh shell sessions a few times and get the same initial slow search followed by the quicker one.)
What I'm trying to do is allow on-demand generation of a table showing the number of records modified per day and per month. The test date I'm searching for above is the date of insertion of records so it returns a comparatively large result set at the moment, but 29-odd seconds is way too slow to make the query comfortable. I've added a substring index because sometimes I want a partial date search (e.g. when counting records modified per month). I remember reading that a substring index doubles as an equality index. The date is stored simply as a string, not a date type.
What am I missing? I'd like to understand the difference in execution times, but basically I need it to run more quickly for simultaneous date queries. I'd be grateful for any pointers.

Oracle/VB program runs slow then fast

We have a version 13 application (running now with lots of data)that we want to upgrade to version 17. Both are Visual Basic/Oracle aps.
Because the layout is different between the two database's we wrote a long script to pour into the version 17 structure the version 13 data. We have to turn off all constraints.
Version 17 runs but reports run very very slow.
Just by chance we did a backup "dump" of the version 17 database. Then we just happend to take this dump to another machine, imported the data and ran version 17. It runs fast again.
What gives? Any ideas
my e-mail [email protected]

Sounds like the first machine has a bad environment (are the two machines running on the same type/speed of processors ?). Re-installing the software might help in this matter.
Sorry I can't be more specific !

Safari slow - FireFox fast

I just come U.S from China. I am using school's network now.
the soft update always report error, can not link to the sever. and safari, itunes, quicktime link very slow. just like through a slow proxy. but haven't set any proxy
the firefox works well. skype works well, ichat works well.
my friend told me, maybe is the DNS error. I try to link google by ip and web address with safari. they spent same time, about 3min, while firefox about 1sec.

golden grape - Welcome to the discussions!
DNS problems are very irritating - and some of the hardest to figure out.
Let's start gathering some information to see how things are set up. Open the Network Utility and go to the "Lookup" tab. Pick one or two addresses and look them up. How long does the server report it took to do the lookup (query time). How long did you wait from clicking go?
P.S. sometimes the best thing is to ignore these things for an hour or so - it's often a temporary thing while your DNS server works out the addresses you need. Also - mac OS will cache the addresses - so once you have them - you don't need to wait anymore on DNS to find things. Try to leave your mac on as long as possible - unless you have some bad software or corruption on a disk - the longer it runs, the faster things will get.

7ms! Your DNS server is a lot faster than mine.
I can confidently say that you don't have DNS problems. If you had DNS problems - firefox and Network Utility should be equally slow. This really has nothing to do with mini hardware either.
It would be best to ask a new question titled "Safari slow - FireFox fast" in the Safari group. I'm sure a lot of people there will have good ideas to find out what causes safari to go slow when firefox can browse the same site with speed.
http://discussions.apple.com/category.jspa?categoryID=169
One things I can suggest is:
* Temporarily change your Safari preferences to open the bookmarks or a blank page. You will know if safari is waiting on something locally or the web page is drawing slowly. I doubt this is it - but you never know until you try to narrow down what exactly is slow.

I am using school's network now.
Does the same thing happen if you connect to the internet through 'normal' means, such as a home internet connection (broadband, dialup etc), or does it just happen at school?

I amexperiencing a very slow log in's and speed to my desktop is very slow also. What is the cleanup I have to do to make this faster

How large is your hard drive and how much hard drive space do you have left?
Sluggish Finder - Bunch of icons on your desktop? An overcrowded desktop slows down your Mac.
Get rid of needless Finder calculations - Open a window in Finder/View/Show View Options: ensure "Calculate All Sizes" option is unchecked.
Internet related - It's likely that your broadband connection is the bottleneck. You can check your speed on http://www.speedtest.net to see how fast your connection is. If your web browser specifically performs slowly, quit and relaunch it.
If browser remains sluggish, empty its cache.
Safari/Empty Cache
Firefox/Preferences - select the Network tab of the Advanced preferences and click the "Clear Now" button in the "Offline Storage" area.
Application related - Launch "Activity Monitor" - Applications/Utilities - click the CPU heading and see what float to the top. If an application takes up a large chunk of CPU and won't let it go, it could be dragging down your Mac's performance. Quit it by clicking the Quit Process button at the top of the Activity Monitor window.
Too little ram - max out your ram.
It is very difficult to offer troubleshooting suggestions when the "os version" you are using is unknown as each os has their own troubleshooting solutions. Which model Macbook Pro are you using?

Recording with audio playback slowed down 65% what speed do I need to speed the video back up to to get it into real time?

Ive recorded a test video with audio/music playback slowed down 65% what speed do I need to speed the video back up to to get it into "real" time?
If I'd slowed the audio playback down 50% I would make the video 100% faster.
If I'd slowed the audio playback down 100% I would make the video 200% faster.
So its obviously somewhere inbetween speeding up by 100-200%
Sorry but its melting my brain today and I cant remember the calculation.
thanks

hey all
Thanks for the advise on this. I will explain a little more what am have/am intending to do.
I have used Audacity to slow the song down (Effect>Change Tempo)
Audacity will allow me slow the original song down by up to 99% (Or anything in-between up to 3 decimal places)
Unfortunately I am working to a time restraint of 12 minutes per clip (as my DSLR will only allow up to a 12 minute clip).
The song at normal speed is 4 minutes long.
Originally I slowed the audio down by 50% (Making the audio 8 minutes long), lip synced to it using a rasta blaster and recorded the video using my DSLR at 720p 50fps.
I then imported the video and audio I had been lip syncing to into FCPX.
I sped up the video by x2 (equivalent to speeding it up 200%)
Retime>Fast 2X
Layered the PROPER normal speed audio back over the top and all was fine.
Test video complete.
(You can ignore the 65% slowed down audio I mentioned earlier if you like, that was just an example of a slower than 50% audio test)
Firstly what I really want to do is to be able to slow the AUDIO down as much as possible (But still within the restraints of only being able to adjust FCPX retiming within a whole 1 percentage in the final video edit), but have the AUDIO of the song as near to/under 12 minutes as possible.
I will then re-record the video again to this new slowed down audio.
Secondly I will speed up the video from 12 minutes to 4 minutes.
Thirdly I will layer the correct 100% Normal AUDIO on top.
The FINISHED video should then look like everyone is wizzing around at high speed but the guitar playing/lyrics look like they are being played/sung at the normal speed.
Whatever happens (due to the constraints of FCPX) I need the calculations to work so that FCPX is retimed exactly to a whole 1% for the final video to sync up correctly.
So what I need to know in a nut shell is:-
What calculation do I use to work out the percentage to slow a 4 minute song down to a 12 minute song?
What calculation do I use to work out the percentage of how much I need to then speed the 12 minute video up to turn it back into a 4 minute video?
My mind is melting

Should using the software update service be faster for the clients then downloading from apple?

I've got about 25 clients, a mixture of Snow Leopard and Lion systems in the office. I've recently turned on the Software update service on my snow leopard server (10.6.8, mac mini) and have a transparent server setup for the software updates service (dns redirects through the mini). All the machines see the mini and I believe they are pulling updates from it when the client runs their software update. I haven't noticed any real speed differnce though from pulling updates from the mini vs pulling from apple (though I have noticed less internet congestion).
Should this be faster because it's a local network transfer or not?
Thanks!

I'm a little concerned by the statement:
dns redirects through the mini
Are you saying you're masking Apple's DNS so that requests for swupdate.apple.com end up on your machine? That's the wrong approach. You should be setting the client's preferences to load from your server instead of Apple's.
In either case, there are three components to running Software Updaate.
1: download the catalog of available updates and compare what's installed to the list to identify which updates are needed
2: download the appropriate updates
3: install the updates.
Of the three steps, downloading the catalog is a lightweight process - the index is only a few hundred KB, so the difference in loading this from your server vs. Apple's is minimal. Additionally, this won't make any difference in the amount of time it takes the client to scan for which updates are needed since that's all work performed locally on the machine.
The only step that will be significantly faster is the actual downloading of available updates. These should happen at LAN speeds, rather than your internet connection speed (which is, presumably, slower), but then again, most updates are fairly small - a few megabytes is typical.
However, if no updates are available, or if they're only small, you won't see much difference in time between local and remote. The main advantage of using a local software update server is that you only need to download the updates from Apple once, rather than once per client.

Internet running slowly, videos not playing well, everything slowing down. Wifi signal is strong, not sure what the problem is. Help please.

You can cancel the reboot to run another cleaning section, just make sure you reboot at the end before using the computer.

Also use the Firefox web browser, it's insanely faster, the fasest of all browsers. The choice of Add-ons is numerous, personalization is just awesome. Everything can be changed, moved around etc. Persona's, themes etc. Just insane.
Not only that, Firefox is for Windows, OS X and Linux, the same browser on all.

I have always heard that Macs are less likely to get infected with a virus. My computer has been running much slower since I installed Maverick. Just not sure what the problem might be. Is there a way for me to run a diagnosis?

I have always heard that Macs are less likely to get infected with a virus. My computer has been running much slower since I installed Maverick. Just not sure what the problem might be. Is there a way for me to run a diagnosis?

Some have found relief just by reinstalling, but it is more than likely incompatible third-party applications that slow it down.
You will have to investigate to see what it is.
Open Activity Monitor and see if anything is using a lot of CPU% or Memory. If they are, check to see if there is an update for them.
Another place to look is the Console. See if anything is logging repeating messages with throttling and/or respawn in the All Messages list.
Sometimes it is not that easy to root out the problems, but if you have anything that purported to clean, protect, optimize, maintain, or flush your system, then that is likely the cause.

Can anyone explain in the Boundary Groups the Setting of Connection SLOW and FAST?

Hello,
we have many locations with DP´s and created Boundary Groups with the Connection FAST.
Now we have some Clients outside they are connected only with UMTS or DSL.
For DSL the connections is set to FAST and for UMTS is set to SLOW.
I must explain that i take over a configuration because i am a new employee here.
Can anyone explain me the different, in detail, of SLOW and FAST?
thank you well and with best regards.
André

Quote from here:
http://technet.microsoft.com/en-us/library/gg712679.aspx#BKMK_BoudnaryNetworkSpeed
"You can configure the network connection speed of each distribution point in a boundary group. Clients use this value when they connect to the distribution point. By default, the network connection speed is configured as
Fast, but it can also be configured as Slow. The network connection speed and the deployment configuration determine whether a client can download content from a distribution point
when the client is in an associated boundary group."
So basically, when you deploy something, this setting determines does the client download the content or not. Shown in the bellow picture:
For example, if you have a client configured inside boundary group that's 'Slow' and then you deploy something to this client, you can configure does the deployment run or not.

One safari is fast but the other one is extremely slow while open the same website!

When i open nrich.maths.org on my two macbook pro, one is fast but the other one is extremely slow. I traced this website on both but seemed nothing difference.
My safaris are both version 5.1.2 (7534.52.7), os are 10.7.2, settings of safaris are same.
I also tried some other sites but all's fast.
Anybody have any ideas?
Appreciate!
Tony

On the one that's slow...
Go to Safari > Preferences - Extensions. If you have any installed, turn that off, quit then relaunch Safari to test.
If it's not an extension issue, try troubleshooting the Safari .plist file.
Go to ~/Library/Preferences. Move the com.apple.Safari.plist file from the Preferences folder to the Desktop. Qui then relaunch Safari to test. If Safari speeds up, move that .plist file to the Trash. If not, move it back to the Preferences folder.
Empty the Safari cache more often. From the Safari menu bar click Safari > Empty Cache
If that doesn't help, back to the menu bar, click Safari > Reset Safari. Select the top 5 buttons, click Reset.
~ (Tilde) character represents the Home folder.
For Lion: To find the Home folder in OS X Lion, open the Finder, hold the Option key, and choose Go > Library

Video slower then the sound..

I bought a movie and it worked fine until I was prompted to upgrade Itunes. Now the video is slower then the sound. If I delete the movie can I re-download it? I have seen other people post something similar and no one is getting a answer... If I can't get a fix to this I will not get another movie on Itunes.

Two questions, What IPOD Software version are you
running and what software program was used to convert
the videos with?
First off mainly it is what firmware you are running, not what you convert the videos with, Barbara please get your stuff straight, I don't even own an video Ipod and I know it has nothing to do with conversion, jeeze.
