@doctator (0xDEADBEEF)💾 ZFS ARC Cache Explained 💾ZFS uses RAM as a powerful cache called the ARC (Adaptive Replacement Cache) to speed up disk reads and metadata operations.It looks like ZFS “eats” RAM — but it’s actually putting your memory to work, caching data for blazing-fast access.⚠️ Important: ARC is not a memory leak! It dynamically adjusts — if apps need RAM, ARC frees it instantly.🛠️ You can set a limit with zfs_arc_max so ZFS won’t take all your memory.✅ Properly tuned, ARC boosts performance without starving your system.So don’t fear the RAM usage—embrace the cache! 🚀<a href="https://infosec.exchange/tags/ZFS" class="mention hashtag" rel="nofollow noopener" target="_blank">#ZFS</a> <a href="https://infosec.exchange/tags/Sysadmin" class="mention hashtag" rel="nofollow noopener" target="_blank">#Sysadmin</a> <a href="https://infosec.exchange/tags/Storage" class="mention hashtag" rel="nofollow noopener" target="_blank">#Storage</a> <a href="https://infosec.exchange/tags/Linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#Linux</a> <a href="https://infosec.exchange/tags/FreeBSD" class="mention hashtag" rel="nofollow noopener" target="_blank">#FreeBSD</a> <a href="https://infosec.exchange/tags/TechExplained" class="mention hashtag" rel="nofollow noopener" target="_blank">#TechExplained</a>
