Memory footprint question (5.0.28)

I had a question on individual memory footprint of a tomcat instance
and increasing the number of instances:
Is this assumption correct that increasing the number of instances of
tomcat on a machine and modifying the IIS worker properties to have more
worker instances in the balanced_worker property will reduce individual
tomcat memory foot print?
For example, currently we have one machine has 3 tomcat instances
running, the IIS worker properties, balanced_worker property points to the 3
tomcats and each worker lb_factor is 1. Current snapshot of memory
usage is approx 175MB. If we add more tomcat instance and add them to the
balanced_worker also, will the memory usage reduce for individual tomcat
instance; now that the IIS will spread the new requests evenly among
the tomcats?
Thanks,

hm, I just recognized something
as I already installed my framework on different systems to try it I suddenly found something that differes from one installation to the other, namely in MySQL.
As I installed XAMPP, I can easily access MySQL via phpMyAdmin. This software views the current available databases in a dropdown menu on the left site of the screen. Further I got two database including an underscore in their name.
If I go into the rights tab of phpMyAdmin and go on to change the rights for my specific user (that generally has no rights, except for that one database, I try to connect to) then I can specify detailed rights for different databases.
If I klick on that specific rights button then the names of my underscore including databases switch from DATABASE_NAME to DATABASE\_NAME (in other words I see a sort of escape sign before the underscore).
Can this cause a problem? Because the name itself is available as a link to the database, which in case of "\_" including names is broken...
I didn't see this in any other installation before, but I also just tried to acess the database via this name or via \ (its acsii sign instead).
puh, its to early here for this sort of things ;)

Class load and instance memory footprint questions

Lets say I have CLASS_A that has three members:
private int a;
private int b;
private int c;
but lets say Class_A has 32 methods manipulating the state of the object.
For argument sake lets say when CLASS_A is compiled this class (Bytecode) file comes out to be 32Kilobytes.
Now when my compiler has to load this class it loads the whole 32 kilo class file. but for subsequent instances of CLASS_A will the footprint for each instance be 32 Kilobytes or will it be the 12 (4X3)bytes that are needed to represent the member variables (+ some more bytes to refer to classname or something)?
I guess my question is does each instance take up 32 Kilobytes?
Thanks for all replies !

No, each instance (within the same JVM process) will take up the amount that the instance variables take up, not that plus the instance methods. The implementation code won't get loaded multiple times.

I'm on iTunes 11.0.0.63 for Windows. iTunes used to display the total number of songs in my library, along with total playtime and memory footprint, at the bottom of the window. How can I make it display this information like it used to?

Hello! Thanks in advance for reading my question.
so, I updated iTunes to 11.0.0.63 on Windows, and the new layout looks nice, but iTunes no longer gives my total song count, memory footprint, and total play-time at the bottom of the window, the way it used to. I just want to know how to get that info back. Thanks so much!

Ctrl / or View > Show Status Bar should do it.
Weirdly having turned mine on the menu is not there to hide it again and the shortcut doesn't work.

Memory footprint

hi,
i have seen lot of mobile database vendors advertise their product's memory footprint. however, have found no corresponding information about oracle lite besides the official "oracle database lite is a small footprint, java enabled....".
so the million dollar question is...what is the memory footprint of oracle lite 9i and 10g?

We use pocket PC devices, and the oracle lite foot print itself has not been an issue.
By default the databases will be created in the following locations
1) SD or CF card
2) built in storage (eg: DELL's)
3) main memory
Main memory is fastest, but can be more fragile (try dropping an IPAQ), but provided you use a fast SD card like Kingston 45x, the differential is minimal, and the size of the card and relative cost provides a lot of advantages (we tend to go for a minimum of 256 MB which should be plenty for normal applications.

How to reduce memory footprint

Hello, while I observed that Audition always loads whole audio document into memory, I'm having quite a problem when processing long multichannel audio files as the whole physical memory gets utilized instantly I'm getting exhaustive disk swapping. This is especially awkward for long operations. I'm having a question if there's a way to reduce the memory footprint, ie. to Audition loads into memory just the file part that it's just working with, or to turn off undo. I assume the rapid memory usage is caused by collecting undo data also, whose I don't need in most cases.

You can use the Clear History button in the History page to clear all undo data or selectively clear individual steps from History.

Low Memory Footprint JVM needed, Please suggest.

Hi guys,
I want a light weight (low memory footprint) Java Virtual Machine compatible with Java 1.5. It should be open source. Can anybody suggest me please. I've googled and tried to use some JVMs like Kaffe and SableVM. But I want some reliable VM.
Thanks,
Dhaval.

You need to tell us what tool you are using to arrive at those numbers.

I want to check all functions of PCI 6534.I have read the user manual..I have some memory related questions.Please help me for that.
1.)If i am using the continuous output mode.and the size of generated data is less than 32 MB.If i want to preload the memory,what should i do?I want that first of all i load all my data to onboard memory & then i want to make start the transfer between 6534 & peripheral.Is it possible?As per me it should be.Plz tell me how should i do this?I think that in normal procedure the transfer between 6534-peripheral & outputting data from pc buffer to onboard memory works parallely.But i don't want this.Is it poss
ible?
(2).Similarly in finite input operation(pattern I/O) is it possible to preload the memory and then i read it?Because i think that the PC memory will be loaded automatically when 6534 acquires the data and then when we use DIO read vi the pc buffer data will be transferred to application buffer.If this is true,i do not want this.Is it possible?
(3) One more question is there if i am using normal operation onboard memory will be used bydefault right?Now if i want to use DMA and if i have data of 512 bytes to acquire.How will it work and how should i do it?Please tell me the sequence of operations.As per my knowledge in normal DMA operation we have 32 Bytes FIFO is there so after acquisition of 32 bytes only i can read it.How it will known to me that 32 bytes acquisition is complete?Next,If i want to acquire each byte separately using DMA interrupts what should i do?Provide me the name of sourse from which i can get details about onboard memory & DMA process of 6534 specifically
(4).In 6534 pattern Input mode,if i want to but only 10 bits of data.and i don't want to waste any data line what should i do?

Hi Vishal,
I'll try to answer your questions as best I can.
1) It is definitely possible to preload data to the 32MB memory (per group) and start the acquisition after you have preloaded the memory. There are example programs on ni.com/support under Example Code for pattern generation and the 6534 that demonstrate which functions to use for this. Also, if your PC memory buffer is less than 32MB, it will automatically be loaded to the card. If you are in continuous mode however, you can choose to loop using the on-board memory or you can constantly be reading the PC memory buffer as you update it with your application environment.
2) Yes, your data will automatically be loaded into the card's onboard memory. It will however be transferred as quickly as possible to the DMA FIFO on the card and then transferred to the PC memory buffer through DMA. It is not going to wait until the whole onboard memory is filled before it transfers. It will transfer throughout the acquisition process.
3) Vishal, searching the example programs will give you many of the details of programming this type of application. I don't know you application software so I can't give you the exact functions but it is easiest to look at the examples on the net (or the shipping examples with your software). Now if you are acquiring 512 bytes of data, you will start to fill your onboard memory and at the same time, data will be sent to the DMA FIFO. When the FIFO is ready to send data to the PC memory buffer, it will (the exact algorithm is dependent on many things regarding how large the DMA packet is etc.).
4) If I understand you correctly, you want to know if you waste the other 6 bits if you only need to acquire on 10 lines. The answer to this is Yes. Although you are only acquiring 10 bits, it is acquired as a complete word (16bits) and packed and sent using DMA. You application software (NI-DAQ driver) will filter out the last 6 bits of non-data.
Hope that answers your questions. Once again, the example code on the NI site is a great place to start this type of project. Have a good day.

Lightroom's large memory footprint

After massaging many pictures in "develop" mode, the system began to become very slow (like locking up for 30 seconds). I opened process explorer and found LightRoom was consuming 1.8Gig of virtual memory and had a working set of about 1.2Gig. This seems quite excessive for general photo editing. I'm really only performing simple adjustments like color and contrast.
I closed down Lightroom and restarted it, and it then worked fine again for another 50 or 60 pictures, at which time slowness occurred again, and the memory footprint was up again. Now that I know what to expect, I'm shutting LR down every 30 pictures or so to avoid the excessive memory consumption.
I suspect there is a memory leak or creep in LR.
I have a machine with 4Gig of RAM, running Vista Ultimate.

EricP,
LR does "accumulated background work" when nothing else is going on, esp if you have the Library set to All Photos. Also it appears that LR is very sensitive to where the pagefile(s) are located and their size. I only can speak to XP Pro though. Vista is a different animal. You might try putting a controlled size [1.5 RAM size for both Min and Max values] on both [or more] HDs you have. Also set the system to keep as much of the Kernel in RAM as possible and set the system to optimize for Applications. Those changes helped me. If they can be accomplished in Vista, they may help also.
Good luck and keep us informed if you get any fixes working.

SQL Developer Memory Footprint

We're looking at replacing around 200 TOAD licenses with SQL Developer. The only technical concern is the memory footprint, as in many cases it would be run from a terminal server with dozens of people logging on. A VM Size of 150MB seems to be not unusual for SQL Developer, and that all adds up of course.
Are there any recommendations for reducing the memory footprint, or at least not letting it get much higher than 150? Features that can be turned off by default, versions of JDK, etc?

Hi,
The memory consume is quite worrying.
However change the code into VB / Delphi will lose its availability as Java's write once run anywhere. :-)
You won't be able to use this tool on Solaris, Linux, and Mac without changing the code and compiler. Thus would be less acceptable.
I wonder if limiting SQL Dev's initial class load would give impact on memory consume.
And why it seems that Java's garbage collector didn't do any collecting since the memory gets higher and higher time by time.
Or maybe the code doesn't allow the object's become collectable?
I ever get memory reach up to 500MB after doing a canceled Export Wizard for USER.
But..... memory would never come down.

Firefox memory footprint

greetings,
i write regarding the memory footprint of the mozilla-firefox package for arch. i downloaded the gtk2/xft binary of firefox 0.9 from the mozilla website and used it in anticipation of the arch package being released. previously on my arch box i had used the mozilla-fire* package rather than the mozilla.org binary. but now i have noticed a discrepency in memory footprint between the two. 'ps v' gives for the arch package and mozilla.org package, respectively:
<pre>
1798 pts/1 S 0:04 0 66 37829 23280 18.2 /opt/mozilla-firefox/l
1979 pts/1 S 0:06 9 9190 27345 19564 15.3 /tmp/firefox/firefox
</pre>
both were taken immediately after firefox startup. this seems to be a pretty significant difference. it is enough for me to prefer the mozilla.org package on my obsolete box with 128 megs ram, anyway.
p.s. i've been using arch for some time now. i would just like to take this opportunity to thank those who created and maintain arch linux. it is an enjoyable distribution

i have mozilla-firefox using mem this way:

and i cannot see any problem with that
but i found out something strange while running it:

Safari on Windows has huge memory footprint

Running Gmail app:
Safari - 85,304K
IE7 - 33,884K
Firefox - 28,572K
I know it's a beta, but I've noticed that Firefox seems to be the best still. It's the smallest memory footprint, it's as fast (that I can humanly tell) as Safari, and the most standards compliant.
There are still some web pages that use heavy AJAX controls and other JavaScript stuff that Safari doesn't do well with. Hopefully they'll get ironed out in the beta and the memory footprint under better control.
IBM ThinkPad Intel Duo Windows Vista

Hmmm... Firefox conservative with memory? Thats a good joke!
The other day, I was surfing the web, and doing little else, when I noticed a marked slowdown in performance (ihave an e67000, and 2gb of ram), so I was annoyed that my system could be faultring just from using Firefox alone.
One look at task manager made my jaw hit the floor! That crafty fox had hogged almost1.35gb of ram!!!! with the optional extras I load up at start, I was left with 34mb to play with! Now thats a ridiculous memory footprint!
Alas this problem has been around since the stone age, the dev guys at Mozilla seem unwilling or incapable of sorting the problem out.

How to minimize OC4J memory footprint?

We use Oracle 9iAS R2 on a Windows 2K server with dual Xenons and 2 GB physical RAM as an integration server. There the various developers all have differenct OC4Js set up for testing. Now an Oracle rep once told us that many OC4Js within an iAS instance are no big deal because an OC4J had a memory footprint of about 3 MB RAM.
That sounded too good to be true. And in our case, is isn't true - an OC4J takes up about 50 MB of RAM right after its start. I tried to minimize the Java heap through the OC4J server attbributes in Oracle Enterprise Manager (like "-Xms16") but that didn't make an ounce of a difference.
So what's the memory footprint of an OC4J inside an iAS instance? And can I reduce it somehow?

This must be a marketing gag. Client Swing Apps tend to consume more than 3MB.
I'm not sure but I guess the iAS is the memory eater. We currently have a test installation on a Solaris machine and the iAS pages up to 3GB when accessing the enterprise manager web site. Have a look into the performance guide and try to switch off all unecessary things. Note that there are to different VM switches: -Xms configures the initial heap size a VM should have (growing is expensive) be whereas -Xmx configures the max size the heap can grow (wheares 64MB is default). Again the documenation says that 2MB is then min (not much availabe for OC4J).
I've you found it - please tell me! :-)

Firefox 27 memory leak (/questions/978195)

I already did this, sorry , but now I include the automated information.....
More than 6GB in 3 hours (MacOSX 10.7.5, 16Gb RAM)
(No time personally to look at this but, I have tagged it as escalate)

I will make a quick comment, but am unlikely to get back to this again before the weekend.
First do not think we are ignoring this or saying it is not a problem. It is a case of it is something often difficult to pin down and must initially be checked and compared with Firefox in a clean configuration, and using memory figures from the Firefox's reporter about:memory.
If you can ramp up memory usage to 6GB in only 3 hours at least it should be relatively easy to demonstrate whether or not something prevents that from happening.
As a test please
*Make an new additional Firefox Profile,
*Run Firefox in Firefox's safe mode
*With all plugins disabled
* Look at memory use by using ''about:memory''
* Browse for a few hours, has the problem now disappeared ?
Instructions and discussions about this can be seen in thread
* ''Firefox 26 on OS X 10.9.1 still has huge memory usuage (leak) which leads to crash'' [/questions/981674]

Memory footprint is HUGE

I just wanted to see if anyone else has a concern with the memory footprint and when/if this will be addressed. We have an ADF web app and now when we try to run under jdeveloper 11G the combination of jdeveloper and the weblogic java process is over 900M and grows when you do any clicking around. Under the previous TP4 release this was less than half.
I have windows XP with Firefox, OracleXE, jdeveloper/weblogic and the memory footprint is at 2G. We already had to upgrade our systems, do we need to upgrade yet again???

It seems that the commandline for starting the embedded weblogic has two instances of the -Xmx and Xms parameters. I think the last one is the one that is used, and it is set to 1024M, which is large for a large portion of development projects.
The parameters are present in setDomainEnv.sh/cmd. It is situated in <JDEV_HOME?>system11.1.1.0.31.51.56/DefaultDomain/bin
I've seen this directory show up in funny places so search for it if you can't find it.
I've set the second set of parameters to the same as the first ones -Xms256m -Xmx512m.

Memory Footprint for LabVIEW 7.1 Full Development System

Hello,
I would like to know the memory footprint for LabVIEW 7.1 Full Development System.Both during the installtion and for developing applications later.
Can someone help.Thank you.
Solved!
Go to Solution.

There isn't a single answer for that, as this varies considerably.
As far as disk space goes, if memory serves, the basic 7.x takes up a few hundred MB, but that could inflate considerably depending on which modules and drivers you add to it.
For RAM, I believe 7.0 used to take up ~20-50 MB immediately after being loaded, but that number would then also change a lot over time depending on what you do. Loading, editing and running code all regularly change the amount of RAM used.
Why are you asking? Also, are you aware that 7.1 is relatively old by now (came out 7 years ago)?
Try to take over the world!
