Lubuntu:Notebook je abnormálně pomalý?

Můj notebook je docela nový (méně než rok) a má slušné specifikace, ale od 1/2 měsíce se opravdu zpomaluje, i když dělám věci, které jsem mohl snadno dělat dříve (vývoj + procházení).

Díky tomu je nepoužitelný a je to obzvláště zklamání, protože:

  1. můj notebook mohl tyto úkoly zvládnout dříve a
  2. Nainstaloval jsem Lubuntu, protože jsem se chtěl zaměřit na výkon a nestarat se o uživatelské rozhraní

A moje otázky jsou:

  • Jak se mohu ujistit, že nemám program na pozadí, který mi nesežere všechny mé zdroje?

  • Obzvláště mám podezření, že můj procesor nevyužívá své kapacity. Jak se o tom také mohu dozvědět?

  • Existuje šance, že jde o chybu v mé současné distribuci (Lubuntu 13.10), kterou by bylo možné vyřešit s 14.04? (Mám podezření, že špatné výkony nastaly při upgradu na 13.04).

  • Pokud se jedná o hardwarovou vadu, mohu o ní vědět?

Pokud je využití swapu vysoké, může to být důvod, proč je váš systém pomalý. Mnoho notebooků má pomalejší pevné disky 4200-5400 RPM, aby spotřebovaly méně energie a prodloužily životnost baterie. protože swap je typický na oddílu na disku a často na konci, kde je výkon nejhorší, může to způsobit špatný výkon. Také pokud disk začíná selhávat, automaticky se několikrát pokusí přečíst obtížně čitelná data, což způsobí další zpoždění.

Pokud jsou úrovně napájení nízké, mnoho notebooků také sníží rychlost CPU (správa napájení).

Možností, jak zvýšit výkon, je mnoho a správná odpověď se liší podle toho, kde se skutečně nachází úzké hrdlo.

1) Pokud je disk pomalý, možná jej budete chtít vyměnit za rychlejší (řekněme 7200 ot./min).

2)Pokud disk selže, měli byste jej vyměnit. Pokud je k dispozici rychlejší disk než původní, možná budete chtít jít touto cestou.

3) SSD jsou mnohem rychlejší než HDD. (s časy vyhledávání v malém zlomku milisekundy) Toto je také možnost. Možností může být také přidání další paměti RAM do vašeho notebooku.

free také poskytuje informace o množství nainstalované paměti RAM a pokud váš notebook podporuje více, můžete

4)Nainstalujte více paměti RAM, což povede k menšímu odkládání na disk, což také pomůže výkonu.

Všechny tyto možnosti platí také pro stolní systémy.
