Post your iPhone's ram usage. To keep things consistant, do this without any apps running on your phone (save maybe MobileTerminal) and do it without your phone locked.

  1. Get the command line tool 'top' from Cydia
  2. SSH to your iPhone (or use MobileTerminal, you won't get to see everything though)
  3. Type 'top' (with no '')
  4. Sort by RSIZE. To sort, from 'top' type 'o' and then type '-rsize' to get the biggest hogs on top.
  5. Take a screenshot
  6. POST

If you use Grab on your Mac, you will have to be sure to save as a JPEG or something to upload to here.

Lets see what is hogging people's ram.

Mine only has like 5-7 processes running. Not even half of what you guys have pictured.

Boy I'd say that was a key piece of information not mentioned in the initial instructions. I was wondering why the command was not recognized

Sorry about that. I didn't even realize I had installed it a while back. I'll make an edit.

Yea, there are more, you just can't see them. If you SSH in you'll be able to see more processes. That's why I asked you to sort them so you can see the important ones first.

What device do you have? I'm assuming a iPhone not a touch, but what kind? You have a lot more Physical Memory than I do. You have 65 used + 20 Free, so 85 megs. I have 56 used and 11 free, so only 67 megs.

Mine is an 8GB iPhone 3G

Unless I am totally missing something here...you don't use Cyberduck to run the command line because you can't. From your screen shots your clearly using "Terminal" on your Mac to SSH. Last time I checked you cannot run a command line from an SFTP app. Can't comment on WinSCP because I do not use Windows.

My guess is:

1. Install "top" from Cydia
2. Open Terminal on your Mac
3. Type: ssh root@IP address
4. Enter your password: "alpine" or whatever you changed it to
5. Type 'top' (with no '')
6. Sort by RSIZE. To sort, from 'top' type 'o' and then type '-rsize' to get the biggest hogs on top.
7. Take a screenshot
8. POST

Is that about right?

You all have the same amount of physical memory. All iPod Touches and iPhones have 128MB of RAM.

iPhone3G, 16 GB.
 
Weird. Why is that PDAnet is allowed to run, even with backgrounder/insomnia turned off?? :confused:

All of us have that!

I guess I just assumed people knew how to SSH. You mush SSH from a *nix terminal. So either Terminal on your Mac or if you want to SSH from Windows, Putty is a good client program. I'd strongly recommend it.

Yea! I noticed that and MxT2 (For MxTube) on mine. Do you other guys that posted have MxTube installed? Why are these running in the background?
 
Phone idle, no WinterBoard:

Phone idle, with WinterBoard installed but no themes/modifications enabled:

MobileSubstrate and StatusNotifier were installed and active for all three shots.

Very telling. So conclusions I'm drawing is that Springboard RSIZE > 10 is probably due to Winterboard. I may go ahead and ditch it again. I only use it for replacing the icons on 3 apps. Anyone got a better way to do that?
 
Attached is RAM usage on a non-jailbroken phone. Taken with 'Instruments' so some usage is the instrumentation process.

So obviously Springboard is a hog (and necessarily so), but over twice the usage with Winterboard? Hmm..
 
Yep. Looks like Winterboard's got memory issues.

(Plus I've noticed it seems to have a couple slow memory leaks.)

SpringBoard may seem like it takes up a lot of RAM, but keep in mind: it's also responsible for managing App Store applications, providing the seatbelt loading/profile compilation, in addition to its 1.x.x duties....
 
What if you have Winterboard installed, but nothing "on." Same usage as if you didn't have it installed? Or is it still using some memory?

Above someone posted and it shows increased memory usage all the same.

If I start getting worried about speed (I'm quick enough as it is now) Winterboard is the first thing to go.
