Hey, I was wondering if anyone can help me.

My N900 is starting to lag for some reason. It used to be super fast, but now its lagging at times.

As a few examples:

1) I click the phone icon on the desktop. I can hear the phone vibrate when I select it. Now the phone icon doesnt actually go blue, like when you select it. I wait 5-10 seconds and the phone menu appears.

2) Alarm goes off, and I press "Stop". Its stuck on "Stop", after its select in blue for 5 seconds, then stops.

3) I get an email, and it appears on my phone as a yellow bubble. So I want to close that bubble. I press the X, and it closes after 5 seconds.

4) I also frequently get "Hildon-Desktop not responding", asking me if I want to close it, which I say no!

I have restarted the phone many times, and its fast again, but after a few hours its slow again.

Anyway I can find out what is causing this?

I have a few apps installed and Catorise installed too.

Please help me find out what the problem is. I want my phone to be fast again

When it gets slow, open x-terminal and run "top" to see if some process is eating your RAM or CPU. And if the process is something you know what it is and you know it's safe to end, you can end it with command "killall processname" where you replace processname with the actual name of the process.

But don't kill processes that you don't know if it's safe to kill!

Just done this and nothing is taking a lot of CPU? I think its also related to the other "hildon desktop unresponsive" thread....

Weird!

you might wanna clear cache on your web browser, restart then see if it helps. I have a hunch it might be that

how many mp3, videos and pictures do you have on your N900 and microSD? sometimes the pulse audio keep on scanning for any changes and freeze the device. sometimes he hildon crash and you may have to turn it off then take the battery out for 5minutes and start it back on. But your Virtual Keyboard might stopped working after the reboot.

Are you using the load-applet? It lagged my N900 badly when I used it... you could try to uninstall it.

I have no MP3's or Videos. I do have about 2000 images from my holidays.

I am using load-applet, but I never had any issues with it. There is another alternative to load-applet now, which does the same thing

Shall I try that?

yup you can try.. but for me, im not using any load applet since like you it makes my device lag before after uninstalling now its quite ok.. does any body know how to really clear the browser cache

open any webpage on default browser: Web -> Options -> Clear Private Data

Hit browsers top area where you can see page name. From there options -> clear cache.

I would suggest that you turn your mobile off. Take off battery. Put it back and restart your N900 and wait until it settles down (~1min) and test if it still is lagging.
