dv1r 25 Posted June 1, 2021 Share Posted June 1, 2021 I recently migrated to a DS1621+ and the Emby system is pretty slow in its responses. Do I need to do anything special when migrating from xpenology to Synology? I am running DSM version 6.2.4 Emby version : 4.6.1.0 Link to comment Share on other sites More sharing options...

Carlo 4330 Posted June 15, 2021 Share Posted June 15, 2021 Your system is better now correct after the vacuum and database cache size change? Link to comment Share on other sites More sharing options...
dv1r 25 Posted June 16, 2021 Author Share Posted June 16, 2021 Yes, Everything is much quicker. Some whole page loading (like home page or music library main page) still have some delay/lag. I think this might be a RAM issue. I have ordered RAM expansion. After the memory upgrade, I will update here if its still going on. Link to comment Share on other sites More sharing options...

JohnWhitmore 23 Posted June 21, 2021 Share Posted June 21, 2021 Hello, I am curious about this statement Your system is better now correct after the vacuum and database cache size change? I have seen how to vacuum...but is there any info on the cache size and a rough guide on best sizing? Link to comment Share on other sites More sharing options...
Carlo 4330 Posted June 21, 2021 Share Posted June 21, 2021 512 MB is probably the highest you would likely get use of but you can set it higher to 1024 if you like. The memory will only get used if it can be used and won't be pre-allocated. Just make sure you normally have free memory available before updating this setting.

dv1r 25 Posted June 21, 2021 Author Share Posted June 21, 2021 Hi @JohnWhitmore, The DB vacuum did help my system a lot. All of my "critical" issues were resolved. Only a few minor lags remain. I hope this is due to lack of memory. The memory only arrived today and I am having some issues with the installation Once the system will be running for a few days I will report back.

Carlo 4330 Posted June 22, 2021 Share Posted June 22, 2021 What issues are you having with the memory install? Link to comment Share on other sites More sharing options...
dv1r 25 Posted June 22, 2021 Author Share Posted June 22, 2021 Nas issues not emby.. The new memory didn't pass the Synology memtest a few times but at different % of progress. Then I tried to switch slots and the nas went crazy. Reboots and flashing lights. Now I was finally able to properly boot the system and decided it's too late for any more risky attempts. I am doing a controlled shut down. Tomorrow I will install the original memory and contact Amazon. Link to comment Share on other sites More sharing options...

Edit the following on DSM 7: /volume1/@appdata/EmbyServer/config/system.xml If you're still on DSM6 I believe the path is /volume1/@appstore/EmbyServer Change these two lines: <VacuumDatabaseOnStartup>true</VacuumDatabaseOnStartup> <DatabaseCacheSizeMB>1024</DatabaseCacheSizeMB> Link to comment Share on other sites More sharing options...

kaj 240 Posted June 22, 2021 Share Posted June 22, 2021 (edited) In my Synology the folder the system.xml file is in: Emby/config (volume1/Emby/config) I have to give my admin user r/w to the Emby folder so that I can see and edit it.

dv1r 25 Posted July 5, 2021 Author Share Posted July 5, 2021 So after a RAM upgrade and a new SSD cache (thank you prime day ) the system is running smoothly. I set DB DatabaseCacheSizeMB to 1024. I noticed that every time I change something my library scanning stops working and I have to manually run: ~$ sudo sh -c '(sleep 90 && echo 204800 > /proc/sys/fs/inotify/max_user_watches)&' ~$ cat /proc/sys/fs/inotify/max_user_watches To get it back to 204800 Thanks for all the help guys Link to comment Share on other sites More sharing options...
DJX 18 Posted July 6, 2021 Share Posted July 6, 2021 Great. In what area did you get benefits with the SSD for cache and what does Emby store in the cache? Link to comment Share on other sites More sharing options...

Loading pages and browsing the library is faster than before. 5 hours ago, DJX said: what does Emby store in the cache How would I check this? I believe it stores some metadata and some content but this is just my guess. Link to comment Share on other sites More sharing options...
