Why use so much memory?!

I am using Java Desktop on Solaris 10. The Sun Blade150 machine has 768M physical memory and more than 400M is used before I start anything other than mozilla! That's more than double than any windows machines I have ever used.
I just joined this company and I have to use this machine as my workstation. It's sounds crazy to me!!!
Can I shut down anything below? Thanks.

How are you measuring windows memory usage? You might be comparing apples to oranges. The SIZE column from prstat includes virtual memory mapped by shared libraries so if you have several processes sharing the same library this memory is counted more than once. GNOME applets/applications make heavy use of shared libraries, but they also have been known to be more resource intensive than they need to be If you're concerned about memory usage, try removing:
gnome-netstatus; That blinking network applet
mixer_applet2; If you don't need sound, remove the volume control
xscreensaver:
pmap -x <pid> gives a good indication of where a process's memory is being used.

I want to ask something about firefox. why firefox use very much memory? can you develop to reduce memory comsume? this problem is very distrub in my PC with low memory.

I want to ask something about firefox.
why firefox use very much memory?
can you develop to reduce memory comsume?
this problem is very distrub in my PC with low memory.
== This happened ==
Every time Firefox opened

How much memory is Firefox using right now?
# Press '''CTRL+SHIFT+ESC''' to load the Task Manager window
# Click the Processes tab at the top. (Click once near the top of the window if you don't see tab
# Find firefox.exe, and see how many kilobytes of memory it's using.
Showing around 80MB when Firefox first starts is normal. Right now, I have 75 tabs open and it's using 500MB - this varies a lot depending on what you have in the tabs.
Other than high memory usage, what other problems are you experiencing? (Examples include slowness, high CPU usage, and failure to load certain sites)
Many of these issues, including high memory usage, can be caused by misbehaving add-ons. To see if this is the case, try the steps at [[Troubleshooting extensions and themes]]. Outdated plugins are another cause of this issue - you can check for this at http://www.mozilla.com/plugincheck

Why does AVG keep telling me Mozilla is using too much memory?

Why does AVG keep telling me that Mozilla is using too much memory and I have to close and reopen the program?

the Advisor is just telling you the same thing you can see for yourself in the Task Manager; I can open firefox with only a few tabs and then watch the memory usage skyrocket when Firefox should be doing nothing - after a couple of hours it will get up to as high as 1.5GB before it completely hangs and I have to end the process in Task Manager, and this does this with all extensions disabled and in Safemode.

Why does the JRE use so much memory?

I know this question has been asked a million times in one form or another but I have not seen a complete answer yet. When I compile and run the following code under WindowsXP pro, it appears that the JRE is using 3.1MB or RAM. When I run a similar program using C++ the program only uses 630k.
public class HelloWorld
public static void main(String args[])
System.out.println("Hello World");
Why 3MB to show "HelloWorld"? I love Java, it is much easier and more enjoyable to develop with but our applications appear to use large amounts of memory. I realize that making calls to the runtime object to check the amount of "heap" memory we are using will probably show much less memory being used but Task Manager shows 3MB. It is sometimes hard to convince my fellow developers of he benefits of Java when there are strange issues like this.
Thanks in advance

Java uses that much memory because every time you start a Java program, even this small, it loads into RAM the whole Java Virtual Machine. Which is itself a very large C++ program - on the order of several hundred thousand lines. Compare that to your C++ HelloWorld program - and you see the reason for a difference...
So a real question is, is it possible to write a modern Java VM such that it uses space proportional to the size/complexity of the Java program that it executes. Partially that's possible - for example I understand that say native GUI libraries are separate from the main JVM dll, so when you don't use AWT/Swing, you don't waste space with related native code. However, for the core JVM it's probably very difficult to separate parts of functionality such as the interpreter, the dynamic compiler, the runtime system, the garbage collector, the serviceability stuff, etc. They are very interdependent, and thus, probably unless you have this goal from the beginning (and ready to sacrifice some performance/maintainability for it), you can't do that.
There exist, however, a bunch of other JVMs of all sizes, say those used in mobile phones (or even smart cards!), that consume a lot less memory. They, however, typically implement only a subset of the full Java functionality. On the other hand, the HotSpot VM that comes with Sun's JDK, that you probably use, is a full-fledged JVM that implements everything, can be used for huge server apps, etc. - no wonder its minimum memory consumption is a few megs.

Every time I load my igoogle home page opening firefox, it opens it in two tabs instead of one, and then AVG tells me firefox is using too much memory and I should close and reopen it; Why

I open firefox using my igoogle home page and immediately it opens two igoogle tabs on top instead of just one how do I stop it from opening the second one? and then after about two minutes AVG tells me firefox is using too much memory slowing my machine and tells me to close and reopen fire fox...how do I fix that?

Make sure that Firefox closes properly and that that there are no longer Firefox or plugin-container processes left on the Processes tab in the Task Manager. Otherwise session restore will reopen the page(s) from the previous session.

Why does Firefox keep telling me that it is using too much memory, (eg: 235MB) and I should restart Firefox?

Lately Firefox has been popping up a warning while I am on the internet saying, that "Firefox" is using too much memory. It suggests shutting down Firefox and restarting Firefox. It also told me how much memory that is in use at that time. It is usually about 235MB or more. What is normal memory use for Firefox to use while I am on the internet? Does high usage mean that some other person is trying to get into my computer?

OIM 11g using too much memory and not releasing it when shutting down

Hello,
we have a problem with OIM 11g using too much memory (about 5gb) and it's not releasing it at shutdown (4gb still used).
We are using a VM with RedHat Linux 5.6. Originally we had 4gb RAM + 2gb swap file. We installed Admin Server, OAM, OIM and SOA on that machine but quickly realised we couldn't run all 4 programs at once in 6gb. AdminServer could run with 2 other products, but it was a tight fit in memory.
So we increased the RAM to 8gb (still 2gb swap file). But then our problem occured : I start the Admin Server (2.7gb total memory used), then OAM (4.6gb total memory used) and then OIM. After it started the server is now using 9.6gb of memory (~300mb of free memory) ! The problem gets even better : after I shut down everything (OIM, OAM, admin server) the "top" command show that there is still 4gb of memory used even tho nothing else is running on the server ! There is absolutely no other process (other than root stuff) running and no other users connected to the machine. After a reboot, it shows 400mb of memory used. I tried restarting the programs and it did the same thing.
Our intuition is that there might be a memory leak or some bug in OIM that might use up almost all the free memory and it's not releasing it upon shutdown. It might have been there before we increased the memory but have not noticed it since memory was already tight.
Anyone encountered the same problem ? Any idea ? Any suggestion to narrow down the problem ?
Thank you

You can adjust the memory settings for WLS by editing the setSOADomainEnv.sh file that can be found in your /middleware/user_projects/domains/<domain>/bin/ folder. There is an argument called PORT_MEM_ARGS which is used to set your Java memory arguments. This way you can decrease/increase the amount of memory used by each managed server.
I usually type "ps -ef | grep oracle" to see what processes are running by the oracle user. This way the output doesn't get cluttered with root processes.

4.0 firefox is using to much memory

Since I upgraded to FF4.0 it acts like it was running another program in the background. it will lock up and turn the page view to a white overlay and will not react to a mouse command anywhere, not even let you out of that page. it does it with any thing you try to open but not all the time. yesterday my AVG anti virus put up a dialog box that said FF was using to much memory (1 GB). How do I correct it? I am sick of having to reboot to try and use it. I was very happy with the old Firefox . THi version Stinks. Thanks RAY Menzel

Firefox 7 was released today and greatly reduces [https://hacks.mozilla.org/2011/09/firefox-7-is-lean-and-fast/ memory usage]. It's possible that the upgrade will also fix the hang that you are experiencing.

Using too much memory while capturing

I am capturing from my Panasonic deck direct to the G4 via firewire DVNTSC but after only 10 minutes or so FCP quits and it is indicated that I have used up all my 200+GB space.
I think I'm doing something wrong with my settings somewhere because I should not be using this much memory.
Any suggestions?

Do this: log a 12 minute clip then do a BATCH CAPTURE of it.
This gets around the time limit issue of Capture Now. If this still does not work, the symptoms you describe do sound a lot like what people have reported after updating to QT 7.3 with resulting problems with capturing.
If this is the problem, the only sure solution is to erase the system drive and install OSX and your pro apps from the original disks and bring them up to date using the software updater.
If you go this route, either clone your existing system disk or make sure you back up any data on it before you erase the disk. This process will destroy all info on the disk.
good luck.

My I-phone 4 is using too much memory storage. Data

My I-Phone 4 is using too much memory. It shows Apps at 1.44 and Data & Documents at 1.68, not to mention "other" using up more memory. I have tried eliminating apps but nothing changes. How does one get rid of some of this "stuff" that is using up so much memory??
