Synology memory compression. Under Control panel->Hardware & Power, there is optional that given a option to enable memory compression (see the screenshot below). Anyway, It is usually around 30%. It seems to be working great and I’m not coming close to using all the RAM on that NAS. A place to answer all your Synology questions. It had been slower than usual and I had random issues connecting to it. This reduces the need to read and write memory swap files on disk, improving efficiency and responsiveness. I recently installed 8GB of RAM on another NAS and turned off memory compression. Such as, if Memory Compression Memory Compression compresses the least recently used data in memory. That is because compression is in-memory and faster than paging to I have a new RS1221+ and just added a single 16GB memory module to the installed 4GB stick. Is My DS220+ running DSM7 with 18GB memory. But disabling memory When a Synology DiskStation is running slow, you can try to disable the Memory Compression. In most of the new Synology NAS devices, the “Memory Compression” feature is designed to improve system performance Memory Compression uses a fast compression algorithm, typically lz4 for compression ram that would otherwise be swapped out. One thing is true in the article: more RAM is better, if you lack enough RAM things will get slow. It seems that there are a few When the items are needed again, they can be instantly uncompressed. I recently turned off memory compression and it actually reduced utilization by about 10% (and no apparent change to swap)! I know some The OS can move inactive memory pages to swap to free up 'real' memory, which will be better used as disk cache especially on a NAS. Reading the Recently while reading a few things on the NAS (DS918+) I came across the 'Enable Memory Compression to improve system responsiveness' option. Compressing uses a little cpu, but can typically reach an average Under Control panel->Hardware & Power, there is optional that given a option to enable memory compression (see the screenshot below). I recommend to all Synology NAS fellows with upgraded RAM to disable the memory compression enabled by default. Ask a question or start a discussion now. It seems that there are a few varying Have you ever wondered if it was possible to speed up your Synology NAS so that it becomes more responsive? Today on mariushosting you too will learn some I think memory compression is the default because the shipped NAS units have minimal memory installed. Once you expand the RAM , compression is not a virtue since it uses system resources. The web interface was dog slow So this is a huge flaw and problem on synology side from my point of view, but they dont really care, therefore my solution is to simply disable swap and memory compression altogether. When you have Because this involves reads from disk – it’s very slow. In Appliance Console > Control Panel > Hardware & Power > General, you can configure memory compression, power recovery, Wake on LAN, beep control, fan speed mode, and LED For those using a Synology Network Attached Storage device as a centralized storage hub powering many connected applications, lag and When is worth to use compression? I know that stuff like movies, photos and most media won't work very well or see any benefit from using a shared folder with compression, and that use If you try finding THE right memory for a NAS, there are not thousands of options so Synology could at least run some testing on those. Without going into deep technical details, if you upgraded your RAM then When you have multiple applications running and the memory begins to fill up, the dynamic Memory Compression shrinks the size of seldom-used items in memory, minimizing memory Hi! Come and join us at Synology Community. To enable Memory Only side-effect would be that you run quicker out of memory and the system begins to swap. They claim that feature should improve the system responsiveness, but in reality it Recently while reading a few things on the NAS (DS918+) I came across the 'Enable Memory Compression to improve system responsiveness' option. I read that turning off the Synology Memory Compression Recently I've been having issues with my Synology DS1512+. This helps improve general system responsiveness under high server load. Reading the article and seems that Synology Use memory compression if your average ram usage is high while cpu usage is low. What Synology does here is swapping to an area of compressed memory to avoid to swapping to disk, and Memory compression is useful when compared to a system that is under high memory pressure and heavily paging to the HDDs. When memory compression is enabled, instead of paging data to disk to free space, data is compressed in-place, with a very fast . Dumb question: Do I still need "memory compression"? Usage shows less than 10% memory utilization.
