Hello!
I have noticed, that my system slows down significantly when i leave it on for 2 or 3 days. It gets to the point where opening a hard drive with dolphin browser takes about 20 seconds. Mind you, I'm taking about a PC with Core i7 4x4Ghz, 8GB RAM and SSD drive. When i check CPU usage it's only a few percent, and more than 6GB of RAM is free. Where can I look for the cause? |

My netbook's performance degrades pretty horribly when it gets too hot, your temps ok?

| Yup, CPU does not exceed 40-45 Celsius when idle, up to 80 while compiling. |

Nevertheless, it may be that some component does (falsely) report some overheating.
I had a similar problem with my laptop, only that it slowed down already after a few minutes.
Finally, I solved the problem by setting CONFIG_ACPI_THERMAL=n (although it says that disabling this option may destroy my hardware, but I think my hardware just sent wrong data to this module).
Of course, the other thing you might consider is that some program (or the kernel) has a memory leak: Check the output of "free". |

| I am 99,999% sure my components are not overheating. Besides, Windows works just fine. I checked 'free', but didn't find anything useful there. |

well you say dolphin takes a long time, try running dolphin from a terminal emulator and see what its holdup is

| I used dolphin just as an example - whole system slows down. After I reboot it everything is just fine for 2-3 more days. |
