حيلة إحياء الحاسوب القديم ضاعف الـ RAM مجاناً بدون شراء قطع جديدة 💻✨

في زاوية من زوايا العالم الافتراضي، حيث تتشابك الأسلاك الرقمية والبيانات، يكمن سر لإحياء الأجهزة القديمة. هل مررت بتجربة بطء حاسوبك الذي يعمل بنظام لينكس؟ تلك اللحظات التي تتساءل فيها عن جدوى إبقائه حيًا؟

اكتشفنا لكم zRAM. ليس مجرد اسم، بل هو مفهوم تقني يعيد تعريف قدرة الذاكرة. ببساطة، يضاعف كفاءة الـ RAM دون الحاجة لترقية مادية. فكروا في الأمر: كفاءة أعلى، سرعة استجابة، وداعاً للانتظار، كل هذا بتحسين برمجي. جمال التقنية يكمن في قدرتها على التجديد من الداخل.

هذه ليست مجرد حيلة، إنها فلسفة لاستغلال الموارد المتاحة بأقصى طاقة. لمن يبحث عن لمسة سحرية لتجديد تجربة حاسوبه: [شاهد التفاصيل هنا] https://youtu.be/ECkSO35h3QE

If you’re using Ubuntu and want to improve your system’s performance, especially on machines with limited RAM, ZRAM is a great solution, as it creates a compressed block device in RAM, which helps to manage memory more efficiently.

ZRAM is a Linux kernel module that allows you to create a compressed block device in RAM, that effectively increases the amount of usable memory on your system by compressing data stored in RAM, which can be especially useful for systems with limited physical memory, allowing them to run more applications simultaneously without slowing down.

And of course ZRAM works for any other Linux distro too. I’ve long been using it on my Manjaro Linux platform.

This guide will walk you through installing and configuring ZRAM on Ubuntu.

SystemD-Swap: Για όσους δεν θέλουν SWAP partition

“Ποιος χρειάζεται Swap στην εποχή μας” θα έλεγε κάποιος. Δυστυχώς είμαστε μακρυά ακόμα από την μη χρήση του Swap. Παρόλα αυτά για αυτούς που δεν φτιάχνουν Swap Partition αλλά θέλουν την “ασφάλεια” του αλλά και να συνδυάσουν τα εκπληκτικά Zswap και ZRam υπάρχει το SystemD-Swap (more…)

My Synology DiskStation DS212j has gotten slower over the years ever since I bought in 2012. DSM operating system security and software upgrades introduced feature bloat that required more memory and caused memory to page to disk. Wikipedia gives an amazing overview of why paging is bad and why zRAM is amazing for memory constrained PCs.

zram (also called zRAM and, initially, compcache) is a Linux kernel feature that provides a form of virtual memory compression. zram increases performance by avoiding paging to disk and using a compressed block device in RAM instead, inside which paging takes place until it is necessary to use the swap space on a hard disk drive. Since using zram is an alternative way to provide swapping on RAM, zram allows Linux to make a better use of RAM when swapping/paging is required, especially on older computers with less RAM installed.

Pretty cool, huh? The Android community often uses zRAM as a way to bring back older devices back to life and I figured I could do the same with my aging DiskStation that only came with 256MB of RAM compared to the more recent DS216 that comes with twice that at 512MB.

I successfully compiled and added the zRAM module to my DS212j and wanted to share the steps. My DS212j uses the Linux kernel 2.6.32 so this guide should be applicable to any Synology DS that uses the same kernel.

Μνήμη RAM: Βελτίωση διαχείρησης με zram – zswap – zcache

Σε περίπτωση που διαθέτετε υπολογιστή με 2GB RAM και λιγότερο πολύ συχνά θα νιώσατε ότι παγώνουν τα πάντα και κάνουν 3 λεπτά να επανέλθουν. Σήμερα λοιπόν θα δούμε τι μπορούν το zram, zswap και zcache να μας προσφέρουν για αυτές τις περιπτώσεις. (more…)
