Dashboard - a memory and bandwidth hog?

Hello everyone,
This is a general question about widgets really, concerning how much of a memory and bandwidth hog they are.
I only have a few widgets on my Dashboard, as I'm worried they'll slow my Mac down. Can this happen, and does it only happen when I 'invoke' the Dashboard?
Also, as some connect to the internet, are they a bandwidth hog? (and again, are they only 'on' when the Dashboard is invoked, or always connected in the background?).
Many thanks for any advice!
Ben

So are these things always running in the background, or only when I chose to bring Dashboard to the fore?The first time you activate Dashboard after log in. Try it. Logout then, back in and check Activity Monitor, then activate Dashboard and check AM.
With AM you can always keep an eye on your memory and quit apps, even if they may not "force quit". However, the way OS X handles memory you shouldn't have a problem unless you're doing heavy lifting like music/video edit.

JRE is a memory and process hog?

Ever since I installed JRE I noticed a big ram usage increase and process count increase when I have websites open that use Java. I am not talking about a small increase.
Prior to installing JRE there were 61 processes open with a single tab on a website with something Java. After JRE was installed it was over 120 processes. I uninstalled and it is back to 61. I kept checking it out and it's all JRE. What is with the excessive need for processes? The websites work fine without JRE. Is there any way to not use JRE within my browser? I only wanted it for compiling/running Java programs!

Google wrote:
An open browser with no site loaded still produces a few extra processes, even more so with websites that require Java (keep in mine these sites worked fine before I had JRE/JDK installed).
For example opening up Gmail would produce about 30-40 processes. I am not sure which is causing the most. I only go to a few sites, gmail, my university webct (required Java, but worked fine without JRE/JDK) and youtube. The processes seem to share the jre/java processes, as if I open many websites the total processes cap at around 125.
Again, Java and JavaScript are something completely different. GMail does not use Java. So why Java gets loaded on your machine is beyond me. It does not get loaded here, neither in Firefox nor in Chromuim, until I visit a site that actually uses it.

Why is Dashboard using up tons of memory and freezing my computer?

I was having this problem on my early 2012 Macbook Pro running Mavericks, and now it is happening on my refurbished late 2013 iMac. I did some research into this and some people were saying that if you run weather apps or similar on Dashboard which constantly update data, it can cause Dashboard to start eating up all your memory. So I ended up disabling Dashboard completely on my Macbook Pro and haven't had any similar issues on that machine. But my iMac has 24 GB of RAM and I'd really like to keep Dashboard running because I like to use it to check the weather or my calendar or use the calculator. Is this a glitch with Mavericks? Has anyone reported this on Yosemite? It's happening more frequently and unless I have Activity Monitor open where I can forcibly quit Dashboard, all my programs start locking up and the whole system becomes unusable and I have to force reset it. You'd think Apple would have fixed this by now. At first I thought it was an issue with my Macbook Pro, but now that I'm seeing the same problems on my blazing fast iMac, I think this is a Mavericks glitch. Any suggestions would be greatly appreciated!
Running OSX 10.9.5 on a late 2013 iMac with 24 GB of RAM, 3.5 Ghz i7 processor, and 4GB Geforce GTX 780 card.

So it looks like the removal of the .plist file didn't fix the problem. I am starting to notice a potential correlation though. I've been keeping Activity Monitor open to check the status of Dashboard to try and catch it before it overloads the memory. It seems that the issue arises generally when the CPU is undertaking an intensive task. Recently I caught Dashboard overloading the memory while I was doing some intensive video compression. The iMac's internal fans started whirring so I went into Activity Monitor initially to see how much memory the compression software was using up. That's when I saw Dashboard starting to eat away memory, and it kept increasing more and more. The compression software was only using about a gig of memory (though a fairly high % of the CPU) while Dashboard steadily increased to 4, 5, 6 gigs and so on. Even after the compression software was done and the CPU started to cool down, Dashboard continued to eat memory. I've attached two screenshots (before compression was done and after) and you'll notice the memory usage of Dashboard (the video compressor was using the ffmpeg process listed)
Here are some system notes I grabbed from Dashboard in one of the tabs from Activity Monitor by double clicking on the process. Maybe these will help solve the problem?

Since new update my games on Zynga hog all my memory and run real slow - I'm frustrated!

I updated firefox and flash as suggested and I have had problems ever since with it hogging all my memory and running real slow hanging up and constantly having to clear cookies and cache multiple times a day. I tried chrome and I don't like it. I like firefox how can this be fixed.

You can check for problems caused by recent Flash updates and try these:
*disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
*disable protected mode in Flash 11.3 and later
*disable hardware acceleration in the Flash plugin

Plugin Containers hogging memory and Adobe problems

Hi,
I have regular problems with Firefox on my notebook. Firefox memory usage shoots beyond 500MB of memory and becomes extremely slow in any of the below conditions:
1) There are updates ready for some plugins: I thought it might be because I had enabled automatic updates and had made it manual. Still the same trend continues.
2) I run any Adobe application on the browser, like open a pdf from a website, run flash video either from Youtube or any other website.
3) I open about or more than 10 tabs on a single session (typical while reading news articles from feeds)
It was very problematic with FF4, but I continue to see the same trend even with version 5. When this happens, I do not have any other option but to close all the sessions of the browser and restart. Sometimes, Firefox does not go away from memory and I have to manually kill the process from task manager. There are several instances when the processor heated up so much, the fan could not handle and the notebook shutdown automatically. This happened when I had run youtube videos and after the video ended, let the browser window open for long time.
Here is the config information of my notebook:
Toshiba Portege M900, Intel Core i5 2.4Ghz quad core, Win7, virus free, with latest CA enterprise AV running.

Additional info:
The 256-color problem depends on how ActiveX'ed beans are integrated into native (VB, C++) apps.
If the development computer is configured to 256 colors, then on the runtime with 256 colors, the colors are ok.
If the development computer is configured to 16-bit colors, then on the runtime with 256 colors, the colors are wrong (dithered, ugly, wrong).
This tells me that the process where the ActiveX'ed bean is serialized to the C++ application resource file, some palette information must have been serialized out as well.
Question: what possibility is there to tell the ActiveX'ed bean or beans.ocx that it should update its palette?
A windows message? To whom, the ActiveX'ed bean, some component of it (HWND?), beans.ocx or some component of it? Sth that can be done within the bean's code?

SAP ECC6 memory and paging issues

Dear Experts
I have recently upgraded my 4.6C systems to an ECC 6 system (DB2 LUW 9.5 on AIX 5.3 TL9 64 Bit OS)
I have been running the LPAR with 14 GB of memory and we are around 100-200+ users using the system, I was monitoring using nmon and found that Physical Memory was around 99.8% Used   (14311.8MB and 22.6MB was free) also the paging space was around 37.2% in result causing the system at times to run slow which can have a very negative effect on the users.
After further investigation I found that after a system restart the Physical Memory would start around 50.9% and increased at a steady pace until it reached 99.8% that is when the system would start using the paging space which would steadily increase, I found that the only solution was a system restart at least once a week to reduce the memory consumption.
At first glance it looked like a database manger memory leak with the process db2sysc, so I searched the net with the search words u201Cdb2 memory leaku201D and found the following APARs and notes.
APAR JR30285 - Pervasive memory leak when compiling SQL statements that use SQL/XML functions
APAR IZ35230 - There is a pervasive unix-specific private memory leak in the security component
Note 1288341 - Memory leak in APPLHEAPSZ -> SQL0954C
Note 1352361 - Memory leak in shared memory area abrfci
Note 1147821 - DB6: Known Errors and available Fixes in DB2 9.5 LUW
After reading the notes and APARs I decided to updated DB2 to the latest fix pack (5SAP), but after the fix pack was implemented it did not solve the memory problem
I started look at different problems with SAP ECC6, db2 and AIX with paging/memory problems and I found the following notes to do with AIX memory and paging but none of them helped as all parameters and settings were set accordingly
789477 - Large extended memory on AIX (64-bit) as of Kernel 6.20
191801 - AIX 64-bit with very large amount of Extended Memory

1121904 u2013 SAP on AIX: Recommendations for Paging
1086130 u2013 DB6: DB2 Standard Parameter Settings
After even more investigation I found the following evidence suggesting AIX Virtual Memory Manager might have a problem

Contribute "low on memory" and Acrobat won't redraw

I have two issues that I believe may be related. First here's my system information
WinXP SP3
Intel Core2Duo E6550 = (2.33GHz)
3GB RAM
GeForce 8600GTS 512 MB Video
Running two 19" monitors, (at 1440x900 each)
Creative Suite Premium 2.0 (InDesign CS2, Photoshop CS2, IllustratorCS2, Acrobat 7 Professional, BridgeCS2, GoLive CS2Version Cue is disabled.)
Production Studio Premium 1.0 (Premiere Pro 2, Encore DVD 2, After Effects 7, Audition 2)
Contribute CS3, (including Bridge CS3, but I don't use it, I use Bridge CS2 for everything).
First Issue. Intermittently, in both Adobe Reader 9, and Acrobat 7.0 pdf files that I have open will not display in the window properly, unless I reduce the size of the window to something quite small. It will show the desktop in behind the window, or if I open a window on top, it shows that window even when I've moved it.
The second problem is similar, but occurs in Contribute CS3 and is always accompanied by a "Your system is low on memory..." error, until I reduce the size of the Contribute window, at which point, it is so small that it becomes unuseable.
The only other program that I have open at the time is Outlook 2007, with a couple of messages.
As this is happening, I open the Task Manager, see that there is plenty of available Physical Memory, and the CPU Usage is very low, under 10%. I've set my virtual memory paging file to Custom Size of 4591MB.
The only way to fix it is to reduce the size of windows or close all the programs. These two problems occur independently of each other. Sometimes when I'm just trying to open a PDF file.
3GB should be plenty to run Contribute and Outlook, or Acrobat and Bridge.
What the heck is going on?

Thanks for the reply.
Yes I have tried that, but to no avail. The crazy thing is that it only really happens after I've been working in Contribute for a while. Sometimes an hour or more. Then it just starts doing this.
The redraw problem also affects other programs, that are not Adobe programs. For example, when I open a Remote Desktop Connection to the web server where I am publishing, while this problem is occuring, the screen will not "draw" properly either.
I have a feeling that there is something strange about how Contribute, and Acrobat, and Windows share the memory, either the system memory, or the graphics memory.
Could this also be a problem caused by having both CS2 and CS3 programs installed?

Memory and CPU issue

Hi experts,
My Oracle version is:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
PL/SQL Release 10.2.0.4.0 - Production
CORE 10.2.0.4.0 Production
TNS for IBM/AIX RISC System/6000: Version 10.2.0.4.0 - Productio
NLSRTL Version 10.2.0.4.0 - Production
we have 2 node RAC. my client (WAS) connects to the DB using JDBC and establishes connection with the DB.
Now problems is coming that my RAC memory on both the nodes gets fully consumed and CPU utilisation is also very high.
We are using proxy login in our application connection. which means that connection to the DB will be created with a schema(User) and after that Proxy session will be established for a particular user. So for a request we have two session. The main session which we had will schema user becomes inactive and proxy session becomes active.
So this way we have 2 sessions for a request which is not wrong but memory and CPU utilisation are bottlenecked.
Can anyone tell what is the minimum memery that a connection takes even if its idle or inactive.
Regards,
Vikas

JDBC 'applications' quite often don't use persistent connections, and often do not exit gracefully by calling 'exit' or 'disconnect'.
This means the session will continue to exist.
It also means, if you don't establish any form of connection pooling and/or dead connection detection, you can throw whatever amount of memory in the server, and you will continue to report
'Now problems is coming'. Apart from crippled English, the general lesson any DBA should know is how these 'applications' operate, and, contrary to some, you can never ever fight problems caused by applications,
by throwing memory and cpu at the problem.
When I read your text, I also assume the application is not using PrepareStatement calls and not using bindvariables, this is why your 'application' is burning the CPU.
Find those 'application developers', sue them, or better still : Beat them with a whip, and have them fix their 'crapplication'.
Paraphrasing William Jefferson Clinton: It's the application, stupid!

I have a mac mini mid 2011, this device have; 2,3GHz and 2 Gb Memmory.I want to upgrade the memory and i need the list of supported memory modules

i have a mac mini mid 2011, this device have; 2,3GHz and 2 Gb Memmory.I want to upgrade the memory and i need the list of supported memory modules. i am from turkey.

Welcome to Apple Support Communities
The Mid 2011 Mac mini supports 8 GB of memory officially, but you can install up to 16 GB of RAM, so you can use 2, 4 and 8 GB modules. You can buy more RAM from OWC or Crucial.
If you are looking for memory at a local shop, make sure you buy 1333 MHz DDR3 memory. See > http://support.apple.com/kb/HT4432?viewlocale=en_US&locale=en_US

Memory and HDD expansion on Satellite 1805-s203

Satellite 1805-s203
Intel Celeron 800 MHz
128MB expandable to 512MB
15 GB HDD
I've recently installed 256MB of memory and there appeared to be only to slots for memory. To expand my memory to 512MB do i have to remove the 128Mb memory and replace it with a 256?
Also, how else can i upgrade this laptop? Could I increase the HDD? How much could i increase it with 512MBs of memory?

Hello
It is not easy to find precise info about older notebook models. According the notebook info it can handle with max 512 MB RAM. Compatible RAM module is KTT-SO815/256 256MB Memory- (Kingston). Using two of them you can have max RAM and notebook will run much faster.
About HDD is not easy to say for sure but I think you can upgrade to 30 or even 60 GB, but 30 should not be problem.
Bye

Problem with Photoshop CS5. Memory and Harddisk spaces

Just got CS5 Master Suite. Whenever I open photoshop it takes a ton of memory 1 gig +. When I open files it takes up more and more until it takes up all my memory and hard disk space. I open a simple multi layered file that is 25 megs in size to work on it. Before I know it photoshop is taking 20gigs+ of my hard disk space along with 3+ gigs of system memory. Is there a memory problem in photoshop cs5?
Thanks!
Joseph

So I just opened the 25 meg file in photoshop cs5 and watched my free space on my hard drive go down 8 gigs the instant I opened it. It went from 27 gigs of freespace to 19 instantly.
I am running a Macbook Pro with OSX 10.6., 4 gigs of ram on board.
anyone else having simular problems?

UPDATE:
So I just opened the 25 meg file in photoshop cs5 and watched my free space on my hard drive go down 8 gigs the instant I opened it. It went from 27 gigs of freespace to 19 instantly. As I open more files and close others it works till my harddrive goes to zero space... stalls the computer big time. Only way to correct it is to quit photoshop cs5 and wait a few minutes for the space to return... and it takes a few minutes for it all to return.

Problem with out of memory and reservation of memory

Hi,
we are running a very simple java program on HP-UX that do some text substitution - replacing special characters with other characters.
The files that are converted are sometimes very large, and now we have come to a point where the java server doing the work crashes with "Out of memory" message. (no stack) when it process one single 500MB large file.
I have encountered this error before(with smaller files) and then I have made the maximum Heap larger, but now when I try to set it to 4000M
i get the message:
"Error occurred during initialization of VM
Could not reserve enough space for old generation heap"
When it crash with this message, my settings are:
-XX:NewSize=500m -XX:MaxNewSize=1000m -XX:SurvivorRatio=
8 -Xms1000m -Xmx4000m
If I run with Xmx3000m instead the java program starts but I get Out of memory error like:
java.lang.OutOfMemoryError
<<no stack trace available>>
The GC log file created when it crashes looks like:

We are running:
java version "1.3.1.02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1.02-011206-02:17)
Java HotSpot(TM) Server VM (build 1.3.1 1.3.1.02-JPSE_1.3.1.02_20011206 PA2.0, mixed mode)
We have 132GB of physical memory and a lot of not used Swap space, so I cant imagine we have a problem with that.
Can anyone please suggest what to do proceed troubleshooting or to change some settings? I'm not into this Java really so I really need some help.
Usually the java program handles thousands of smaller files (around 500 KB - 1 MB sized files).
Thanks!

You have a one to one mapping? Where one character is replaced with another?
And all you do is read the file, replace and then write?
Then there is no reason to have the entire file in memory.
Other than that you need to determine if the VM (which is not a Sun VM) has an upper memory bound. That would be the limit that the VM will not go beyond regardless of memory in the system.
We have 132GB of physical memory and a lot of not used Swap spaceOne would wonder why you have swap space at all.

I have an iMac 5.1 with Mac OSX 10.6.8 and 2 GB memory and an L2 cache of 4 GB. lately I have been receiving error messages of " start up disk almost full; please delete files." is the start up disk the same thing as the hard drive?

I have an iMac 5.1 with Mac OSX 10.6.8 and 2 GB memory and an L2 cache of 4 GB. lately I have been receiving error messages of " start up disk almost full; please delete files." is the start up disk the same thing as the hard drive? I opened the hard drive and from the column on the left of the menu I've selected "search for" and under that " all images" then "all documents" I've deleted a few files from each. Are documents and images that I have deleted from here also deleted from the folders on my desktop?

You should never, EVER let a conputer hard drive get completely full, EVER!
With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
If it does, it's time for some hard drive housecleaning.
Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
Have you emptied your iMac's Trash icon in the Dock?
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
Delete any other mail in your Junk folders. Also, look through your Sent Mail to see if there is anything that can be deleted.
Other things you can do to gain space.
Once you have around 15 GBs regained, do a search, download and install OmniDisk Sweeper.
This app will help you locate files that you can move/archive and/or delete from your system.
STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
Good Luck!

MacBook Pro, OS 10.6.8/2.8 GHz/Intel Core 2 Duo/with 4 G memory and would like to hook up an external monitor.

I have a MacBook Pro, OS 10.6.8/2.8 GHz/Intel Core 2 Duo/with 4 G memory and would like to add an external monitor. I have the usual ports; 2 USBs, Ethernet, as well as a couple small ports that I do not know what they are for... sorry . First of all, is it possible to add a monitor or TV screen for a larger screen when using? Secondly, if this can be done, what do I need to buy?
Thanks so much!

Yes, it should be possible. I think every MacBook Pro ever sold has some kind of port for an external monitor. You would have to nail down which kind of port your MBP has and where on your MBP it is located.
Can you find the little "getting started" pamphlet, manual, or PDF that came with it? It should name the connectors.
My guess? If the only ports you have besides USB and Ethernet are smaller than those, you could have a Mini DisplayPort.

Dashboard - a memory and bandwidth hog?
