G+_Rud Dog Posted November 2, 2018 Share Posted November 2, 2018 Synology and Streaming Can anyone help with how the cache hardware hinders or helps streaming video either over my LAN or Internet? The hardware in question is the DS918+ with min memory and no cache. Link to comment Share on other sites More sharing options...
G+_Akira Yamanita Posted November 2, 2018 Share Posted November 2, 2018 It would hinder only if the caching algorithm isn’t optimized correctly for the particular workload. Caching helps in three ways. 1. Data is preloaded for faster access and fewer disk operations. 2. Disk activity is deferred, which can be used to speed up uncached high priority requests or give the feeling of fast writes. 3. Recently accessed data (whether a read or write operation) can be read directly from the cache. Link to comment Share on other sites More sharing options...
G+_Rud Dog Posted November 3, 2018 Author Share Posted November 3, 2018 Akira Yamanita I was hoping the cache would fill with video apps like Plex and HDHomeRun. Thereby making them available from the faster hardware. It was wishful hoping as I knew if you opened let's say a spreadsheet on a regular basis it would cache that doc and probably not the entire Excel program.

G+_Akira Yamanita Posted November 3, 2018 Share Posted November 3, 2018 Rud Dog It's mixed. If the app is running on the NAS, such as the web UI for Plex, then that would be cached. However, the UI probably loads just fine on whatever device but the remote UI components (the things that aren't part of the UI itself but needs to be presented) such as video thumbnails, previews, chapter points, etc. would all get a speed boost from having cache, and those are things that are likely to drag the interface performance down.

G+_Daniel Stagner Posted November 4, 2018 Share Posted November 4, 2018 Are you seeing an increase in performance when browsing? This is where the cache should be helping a-lot. Link to comment Share on other sites More sharing options...
