performance degradation in linux

Question

linux

Good evening. I wanted to switch to ubuntu and I like everything about it, but I really feel how my performance sags in comparison with win7.
I installed intel core 2 duo, + almost top-end nvidia 5 years ago, rolled all the latest drivers (both open and closed). The subsidence was felt in those cases when, for example, I opened two browsers and opened many tabs in each of them (20-30), and it’s clearly visible that the page rendering lags terribly, and top shows 100% CPU usage. In Windows, the same thing is surviving decently operatives for me, well, yes, it eats off 15-20 CPUs.
I really want to get off Windows, because it got me and tench is ideologically closer to me (and he is prettier), but such moments make me misunderstood. Problem in my hardware? Maybe it coincided with me that the config does not fit? Or is everyone like that?
Can anyone give an example of their ~15-20k configs that work like clockwork? I'm even ready to buy a new computer :)

Answer 1

A Linux server, especially after proper configuration, can really beat Windows both in terms of performance and economy. With the desktop, everything is exactly the opposite. Applications for different DEs want a different set of services in a user session that perform the same role; another new revolutionary interface requires a bunch of resources to draw one and a half buttons; etc. I advise Xubuntu, XFCE is quite unpretentious in terms of resources and does not require over 9000 hours of work with a file.
Z.Y. What does the processor eat? Browsers or Xorg? Judging by the symptoms, I'm wanking to use some kind of nouveau instead of proprietary NVIDIA drivers.

Answer 2

It's just that Ubuntu is a disgrace to the Linux world. It slows down like hell and always slowed down. Install at least Mint Cinnamon.

Answer 3

NVIDIA drivers
As a rule, such performance drops are usually due to software rendering of graphics. The entire graphics rendering load falls on the CPU, not the GPU.
To fix it, I advise you to install proprietary NVIDIA drivers .

www.ulmart.ru/goods/603874 (not advertising, just on your own site, you'll break your leg) + upgarde up to 8GB + SSD. Xubuntu 14.04 It's just a flight ...
If Chrome then look here chrome://gpu/ And so you just need to look at the hardware specifically, read the forums how to fine-tune it, if necessary, of course. I got almost everything out of the box, but for myself I finished all sorts of little things, in the form of all sorts of super fresh unstable updates, so that life didn’t seem like honey at all.
P.S. I have to run Win7 in Virtualbox for work - so both OSes feel good even at the same time (not great, the machine is still not a beast), but you can work.

Answer 5

change the browser to chrome, it can have many cores
, and in the top, see if it’s just a zayuzan or if the system has gone into the swap a lot or the disk activity is not pulling.

Answer 6

Linux is extremely sensitive to disk IOPS (treated by switching to ssd under / and /home) and the amount of free memory (more precisely, its presence is free, so that there is somewhere to cache).
Those. a configuration like "ssd + 8 GB memory + any multi-core processor" will do. For example, I had an asus eeepc 1000h with ssd and 2 memory - it worked perfectly (as long as there was free memory, but browsers were not so voracious then - it was enough for 15-20 tabs + a couple of dozen consoles).
Now all configs are 8 gig, a browser with a dozen or two tabs steadily eats 4 GB of memory. You can delete plugins from Iron, but laziness - as long as there is enough memory.
Now my weakest config - amd e35m + 4 memory + ssd - works well, XP is better on the same hardware (well, I demolished the ungodly Untiy, put gnome classic mode).

Answer 7

Buying a separate computer is a good idea. And on Yandex.Market, using an advanced search, you can easily find about 50 models (laptops) from the price range of 15-20k with Linux preinstalled.

Answer 8

In my experience, the problem here is either in RAM (when it becomes low, the system starts writing to the swap file, the resulting kswapd process eats up to 100% of the CPU, i.e. everything starts to slow down), or that some then from open browser tabs, for one reason or another, they eat a lot of CPU.
There can be anything - both crooked pages, ads that do not fully load (I had it on firefox with an adblock on some news sites - the page is in a state of eternal loading and loads the processor by almost 100%), and, most often, flash , which can be in the form of banners or videos on one of the tabs. He also loves to eat in Linux.
If Chrome - you can see the CPU usage in tabs through its own process manager. If Firefox - you can kill the plugin-container process (this will disable all flash at once) and see if it helps.
