Application suddenly very slow in debug mode?

I have a WPF desktop application with 10 or so projects. I am using Visual Studio 10.0 SP1. All of a sudden, it has become extremely slow in debug mode - to the point that I can not even debug it.
The same application runs just fine in debug mode on another pc where I am using Visual Studio 2013 Express. I am using SVN to keep the two copies in sync. No new software or windows update has been installed. Even nothing material has changed in the code.
I looked at the VS debug options on both machines and there is no major difference - using default settings.
Any idea what may be wrong? What should I look for?
Thanks.

I take it the path you're using hasn't changed?
You didn't suddenly decide to work off a network drive or pick a very long path to the source ( yes that stuffs things up ).
If you're using the same code and it works fine on one machine but not the other then your visual studio install is probably broke somehow on the slow machine.
I would do an install > refresh.

WebDav suddenly very slow

Today, WebDav became suddenly very slow on my iMac running the latest version of Mavericks. Yesterday everything was OK.
When I try WebDav from my iPad things are OK, so I suspect something is wrong on my iMac. I already tried rebooting and resetting PRAM and VRAM.
Does anyone have a good suggestion?

Hello,
Check to see how much free disk space there is. Right or control click the MacintoshHD icon on your Desktop, then click: Get Info. In the Get Info window, click the discovery triangle so it's facing down. You will see; Capacity and Available Make sure you have 10% available disk space, 15% is better. Insufficient available space, can cause performance issues, system corruption, and possible loss of data.
Check the hard disk for errors.
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.

Applications is very slow after an each deployment

Hello
I'm using JDeveloper 11g 10.1.1.3
I've developed the little aplication with Oracle ADF (full stack: ADF BC, ADF Model, ADF Controller, ADF RC).
That's work fine on the integrated WLS.
Next, I have the standalone WLS on SUSE 11. And I have the next problem: my application works very slow after deploying (for about 15 second for each request), but that is only first time for every page (or every page fragment).
After one user opened the page, all others users open it perfectly fast. Even after rebooting of the server the application is working fast.
I've tried to deploy another applications to that WLS, and to the another WLS, but I have the same problem.
I think there is something wrong with deploying (I deploy all applications from JDeveloper).
That problem doesn't appear with integrated WLS.
What could it be? Maybe, that is usual thing and I shouldn't use JDeveloper's deployment profile?
Anatolii

Hi Anatolii,
Cany you please generate a Thread Dump during load and after deploying your application. This will be able to show us where time is spent during that 15 seconds of your client requests. You also may want to capture the JVM memory figures before and after your deployment by using tool of your choice or simply enabling verbose GC on Java process.
If problem is only happening post redeploy, then you may want to look at some possible native memory leak (classloader leak) here.
On most of our production systems, we always restart (preventive measure) the WL server post deployment, to prevent any build up/leak of native memory (class descriptors etc.).

P-H

After installing NI Scope 3.5 RS232 in my application is very slow!

I am using NI5114 Digitizer. After installing NI Scope 3.5 RS232 in my application is very slow. Un-installing Scope driver doesn’t help. Serial communication from my application (developed in CVI) is permanently crippled. The only fix is re-installing Windows. It happened on three different computers. I am stuck with this problem. Please help
Richard

Hi Richard,
I'm very curious about where you received your NI-Scope v3.5 from, the latest version currently available is v3.4, this can be found here.
NI-Scope does install NI-VISA, which will affect your serial ports in Labview.
What version of NI-Scope does MAX show?
What version of NI-Visa does MAX show?
You could try un-installing both of those drivers then re-installing the NI-Scope v3.4 driver.
Please do post back the results of checking the version installed of NI-Scope and NI-Visa.

MacBook Pro Suddenly Very Slow

Hello all,
I own a mid-2012 MacBook Pro with 8gb of RAM and 2.5GHz i5 processor running the latest version of Mavericks. I purchased it back in December 2012, and have only had one issue with it (graphics card failure, which was fixed by Apple).
Everything else has been fine, as far as I can tell; apps load fairly quickly (such as Adobe AI and PS) and there hasn't been any lagging or glitchy-ness unless I'm gaming.
However, recently (about 6 days ago) my computer started to become EXTREMELY slow. Booting up takes probably double the time it used to take, and opening Adobe Illustrator has taken 2-3 minutes. Once I get Illustrator open, something as simple as a brush stroke will freeze up the machine for about 30 seconds. All other apps act similarly. When I'm playing music with Spotify it will lag and stop playing for a little while and then resume. The computer will even freeze when I do something VERY simple such as hovering over the dock to magnify the icons. Even as I'm typing this message, the computer freezes up every few words and makes me sit and wait 15 seconds before continuing to type.
The issue began the day I installed AutoCAD. Is that the issue, or a coincidence? I tried uninstalling it but the Mac was still very slow and glitchy. I tried uninstalling lots of apps I don't use (and don't know how I got them) like Growl and FUSE. I also cleaned up the HDD and have 118gb out of 500 free, and I ran the Apple Hardware Test (the basic and extended tests) with no problems found. Nothing I've done so far will speed the Mac back up to normal.
I do have a Time Machine backup, so one possibility is to restore the Mac to the backup from a week ago (before the issue began). The only problem with that is I'm afraid I'll lose some of my apps (mainly Adobe CS6) which I no longer have the serial number for, and there's no way I'm risking having to buy it again.
Another option is to move all important files to an external drive, wipe the whole thing clean, and start over. Again, I'd rather not do that for fear of losing my applications.
I checked the Activity Monitor and everything seems normal there:
Lastly: Upon looking through other forum posts like mine, I saw that most people want to see the EtreCheck report to try and help; so here it is:

Thanks to everyone in advance!! I'm a student and couldn't live without my computer. Please help

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

JDeveloper IDE suddenly very slow for past two days

Hi All,
I have Jdeveloper 11.1.1.4 for more than a month now. Suddenly the JDeveloper IDE has become very slow. It is very annoying having to wait for the code changes to show across and windows take long to get in sync. I have 3.25 GB RAM running on XP service pack 3. Also, I scanned my machine for likely virus, but has come clean. It is only with Jdeveloper I am having problems. All other applications are running fine. I even tried just running JDeveloper alone. No luck.
Thanks

Suddenly the JDeveloper IDE has become very slowSeems like something changed.
Did you install any new extensions? When is it "slow?" Is it when doing a specific activity, or just overall "slow?" What does your OS show (is JDev using lots of CPU, for example)? Have you tried making a backup of your "system11.1.1.4.37.59.23" folder (numbers may be different depending on version) and then deleting it so that JDev recreates it for you (you'll lose all of your preferences/settings)?

Internet suddenly very slow 2011 Mac Mini

My internet has suddenly become very very slow.
Wireless.
Last week very fast.
Any ideas?

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
The title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

Macbook suddenly very slow

Hi All,
A couple of days ago, my aluminum macbook suddenly slowed to a crawl. Lots of beach balls, or just freezes with no indication as to why. In addition, certain applications (iTunes, Disk Utility,...) would crash, with crash reporter giving a KERNINVALIDADDRESS error code. I also ran into an error message in Terminal that the dylib shared cache was corrupted, and I wasn't able to rebuild it. I reinstalled OS X, which fixed the dylib and crashing issues, but the computer is still very slow. I've run memtester to investigate whether the RAM is faulty, but didn't find any problems. Disk Utility didn't find any problems with my HD either. Any other suggestions?
Thanks!

HI,
Make sure there's enough free space on the startup disk. Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure you always have a minimum of 15% free disk space.
And help here for the The Spinning Beach Ball of Death

Suddenly VERY Slow Internet On Macbook Pro

My MacBook Pro is less than a year old, running Snow Leopard 10.6.7. A few days ago, the internet suddenly became very, VERY slow. My computer says it is receiving a full signal, and my girlfriend's computer (a Dell, I might add) is on the same wireless network and is working great. I have tried everything suggested to me when searching for the problem online: I've reset my router and modem (but again, my girlfriend's computer is working well on the very same connection and my MacBook claims to be getting a full signal), checked for software updates, emptied Safari's cache, reset Safari, disabled plug-ins, tried Chrome and Firefox (the problem persisted), scanned for a DNS changer and viruses/spyware (the scan came up clean), added open DNS servers, reset my TRAM, repeaired disk permissions and have restarted throughout this process. I cannot trace this changed internet speed to anything - I have no idea what has caused it or how to fix it. Please help!

Hi...
Try Starting up in Safe Mode
That deletes system caches that may help. A Safe Mode boot takes longer then a normal boot so be patient.
Once you see the Desktop click the Apple menu icon top left corner of your screen. From the drop down menu click Restart.
If that didn't help, try uninstalling Sophos > http://help.bol.ucla.edu/app/answers/detail/a_id/879
Then try your browsers. It could be the security software that's slowing your browsers down.
If that helps, you could try a different anti virus software such as ClamXav. It's free and Lion v10.7 compatible.

Macbook is suddenly very slow

Suddenly my MacBook Pro is very slow. Spinning beach ball of death appears across platforms. Might have a virus or malware. What can I run to detect what's up? Any suggestions?

You may be able to improve the speed with some software work but it could also be your disk or SSD is corrupt or failing.
Backup your data immediately:
Before proceeding you should make sure you have a current backup. If it has been getting slower over time your disk could be a failing slowly. SATA drives have two retry modes: short and long. They can continue operating as read errors are increasing. The long retry cycle is very long and can cause significant performance degradation. If it has started long retries then it is likely to get worse and eventually fail. SSDs also have a failure mode where the fail slowly.

Low disk space:
If your disk has less than 10% free space or less than 15 GB free it can slow down your Mac. For information on how to clear disk space see https://discussions.apple.com/thread/5634300?tstart=30 .

(I learned a lot reading this document. Good stuff.)
- A clean install.
After you have backed up your system twice to two different disk drives.
Preferably with one of the backups being a clone.
Time Machine restores are complex and can sometimes fail.
You don’t want to risk all your data on one backup as you wipe out the data on your Mac.
As part of this clean install procedure for disks, erase the disk with Security Option Zero
that writes zeros to all sectors and remaps bad sectors as it does so.
That is a time consuming operation, but worth it.
See https://discussions.apple.com/message/24057867#24057867
If you have an SSD, to not write a pass of zeros to it.

Hardware replacement or upgrade?
Hopefully by now your Mac is back to its normal speed. If a hardware repair is indicated take it to an Genius bar at an Apple store for a free diagnosis and estimate of repairs. If it is under warranty or AppleCare they will repair it for free. If not, you can compare their estimate with DIY repairs.
Genius reservation http://www.apple.com/retail/geniusbar/ .
or find an Apple Authorized Service Provider https://locate.apple.com/country
You can speed it up further by upgrading some hardware. (Do not upgrade the hardware if it is still covered by the warranty or AppleCare.) For the following memory, disk or SSD replacements and upgrades check out OWC http://eshop.macsales.com/, Crucial: http://www.crucial.com/ and Kingston http://www.kingston.com/us/. You will need to know your Mac the year and season your Mac was first sold and model number which can be found here:
 > About This Mac > More Info… > System Report > Model Identifier:
If your Mac has 2 or 4 GB of RAM, consider an upgrade to 8 GB (if the memory is upgradeable). An 8 GB memory upgrade is only $100. When I upgraded a MacBook from 2 GB o 8 GB it booted thee times faster.
If your Mac has a disk and it won’t repair properly, is low on disk space, or you just want a considerably faster disk, check out an upgrade to an SSD-Hybrid disk. Google "Seagate 1TB Solid State Hybrid Drive SATA 6Gbps 64MB Cache 2.5-Inch" or consider an SSD (120 to 480 GB).
OWC has SSD replacements and upgrades for MacBook Airs and Retina MacBook Pros.
Good luck. May the software fixes do the trick.

Macbook Pro all of a sudden very slow.

My Macbook Pro has all of a sudden become very slow. The rainbow wheel shows up about every minute, and battery life has reduced a lot. I lost about 10% of my battery life within 10 minutes. It freezes all of the time. I recently upgraded to mountain lion about a month ago and everything has been fine since about 2 days ago. Any ideas on what it could be?

First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Otherwise, take the steps below when you notice the slowdown.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

My Apple TV is suddenly very slow

I am going to have to use laymen terms here. I purchased my Apple TV a year ago and have been using it successful since. About two weeks ago it suddenly began streaming very slowly and has maintained a very slow rate of transfer between my computer (Windows XP) and the Apple TV. To be frank I cannot use it without frustration. I tried upgrading to 2.0 but it did not help. So I did a factory reset which only put it back on 1.1 ; but the performance is still painful. I have made no changes to my router (ADSL) or my computer that is running iTunes. I have three other laptops that are running on the wireless laptop and they are running fast and fine.
Can anyone help?

davidwh1,
I may have misread your original post... but I interpreted your message to say that you have your information on a laptop, and that the laptop and AppleTV are both connected wirelessly to your router. And if that is the case you can connect your laptop directly to your AppleTV for testing purposes. However, if your iTunes is on your desktop PC, perhaps you could try to sync one of your laptops (if you have iTunes on it) to your AppleTV in order to rule out that it is a connection issue. Sorry if I misread your post and I wish you good luck.
