Re: Did anyone noticed ?

A little off topic, but things may change in memory management in the near future. When solid state hard drives become the norm, and the introduction of USB 3 soon, there are some possibilities for using those as memory that we do not even think about now. Imagine if you could have a huge swap file on a solid state device, with read/write speeds as good as your current memory and adjust your swappiness to use it.

I have 3GB of RAM and my current usage is at 1.1GB with FireFox running. FireFox takes 74.5 MB but I have 8 pipes open, which is why my display speed is so snappy.


Something eating up your CPU cycles may be your problem. I run Skype a lot. Skype ABUSES Linux users by setting up a "SuperNode" (in stealth) which it then uses as a Skype server. If you are browsing on the web after running Skype, even though it is now closed and the Skype daemon is stopped, the Skype supernode may kick in and begin acting as a relay point for other Skype converstions, hijacking your bandwidth to do so. You will notice that your once snappy Internet connection is now dog slow and your wireless modem lights are blinking wildily.

You are more likely to become a skype supernode IF you have a large Internet bandwidth and a fast CPU. Being stelth it is hard to identify and shutting down Skyp and its daemon and rebooting is an easy way to stop it. Windows users running Skype have an option to check to prevent the supernode from being created. Linux Skype users do not.

If things seem slow to you start the System Monitor and click on the CPU column header to sort your listing by CPU percentages. Clock again to reverse the sort, if you need to. Sorted with the highest at the top you'll see the CPU hogs listed at the top.

Re: Did anyone noticed ?

Boy oh boy it eats my RAM alive. I wasn't sure why it stops now and then and getting numb for 3-5 seconds. I opened testing widgets and RAM is "brutally abused"


- Can someone help me optimise RAM ? or just do something about it please ?

I assume you "upgraded" in so far as you retained your home files? I had a similar issue a while back - xorg was using RAM (and CPU) apparently just for fun. I fixed it by renaming the home/.kde file to .kde.old and restarting. Obviously the hassle is that you need to reconfigure kde and if you are running kmail etc you need to shift data to the new .kde folder but it transformed the performance of my machine.

Well, I booted into Ubuntu this morning and Ram usage dropped to .50 GB, that's with Firefox, Thunderbird, System Monitor, and Compiz running.

birkopf, do you have desktop effects enabled?
i have 4GB of ram in this machine right now 40MB free. my server(also linux box) w/ 1.5 gb ram (ddr) has no free ram ever. and is still as snappy ask my desktop.

Re: [solved] Did anyone noticed ?

No, I don't have desktop effects enabled.

Good thinking anyway! Processor usage is ok. as well.

It seems to be more problem with whole new system, not only RAM.
