يا اخى اللينوكس بوجه عام ﻻ يستهلك الرامات او اى شئ

Your ram is fine!


Linux is borrowing unused memory for disk caching. This makes it looks like you are low on memory, but you are not! Everything is fine! Why is it doing this?

Disk caching makes the system much faster! There are no downsides, except for confusing newbies. It does not take memory away from applications in any way, ever! What if I want to run more applications?

If your applications want more memory, they just take back a chunk that the disk cache borrowed. Disk cache can always be given back to applications immediately! You are not low on ram! Do I need more swap?

No, disk caching only borrows the ram that applications don't currently want. It will not use swap. If applications want more memory, they just take it back from the disk cache. They will not start swapping. How do I stop Linux from doing this?

You can't disable disk caching. The only reason anyone ever wants to disable disk caching is because they think it takes memory away from their applications, which it doesn't! Disk cache makes applications load faster and run smoother, but it NEVER EVER takes memory away from them! Therefore, there's absolutely no reason to disable it! Why does top and free say all my ram is used if it isn't?

This is just a misunderstanding of terms. Both you and Linux agrees that memory taken by applications is "used", while memory that isn't used for anything is "free". But what do you call memory that is both used for something and available for applications?
You would call that "free", but Linux calls it "used".

ملخص الكلام ان اللينوكس يستخدم الخالى من الرمات فى عمل كاش للهارد ديسك
عند عمل System Monitor
يخبرك بان الرمات مستخدمه بالفعل فى حيث انك ﻻ تستخدم الكثير من التطبيقات
الجزء الغير مستخدم من الرامات والذى يستخدمه اللينوكس فى عمل كاش للهارد ديسك عند حاجتك له فى
تشغيل المزيد من التطبيقات يلغى النظام الكاشينج ويعطى المساحه الكافيه للتطبيقات

اذا اردت ان تعرف الغير مستخدم فعﻻ من الرامات افتح الترمينال (الطرفيه)
واكتب free -m
