Why is emby server so slow

[Mookdog 90]

Hey guys

I shifted a few hard drives around and quite of bit of metadata needs to be refreshed but its so painfully slow. All the drives are the same drive letter as before and folders didnt change. Also I do save metadata in .nfo file along with posters and it still takes forever. Anyway to alleviate that ?

Hi there, please attach the emby server log from when you thought it was slow. Thanks.

Except for initial startup and, sometimes, when a lot of shows get added all at once I do not find Emby slow at all.

I do not have a particularly fast computer and I use external USB drives mostly connected to a USB 2.x hub pooled using DrivePool. Note: I had problems with using USB 3.0 so I switched almost all of them to the slower USB 2.x ports but video streaming is not very disk intensive so it matters very little.

On my server I run Emby and I run DrivePool to pool all my drives also I have Live TV enabled and I have Channels DVR (for its m3u tuner ability) installed on the server as well and I run TightVNC to allow remote control of the server. With those running on my Windows 10 server I almost never see any slowness at all except when Emby is first starting and that "slowness" only lasts for a few minutes.

That is if Emby is slow it is, most of the time, the "fault" of the local hardware or network. It is not Emby itself.

emby itself is everything but slow. it all comes down to your setup

for example: if you transcode on the same harddisk (important, harddisk, not ssd! never mix the naming) as you read the file from, it will become much slower

or if you save all your metadata on the harddrive you have your media on it will take much longer than if you store the metadata on a ssd while your media in on harddrives and you only read from them

my setup is quite complicated but to sum it up: harddrive -> encryption -> vm -> raid/pool/cluster -> network share -> other vm with emby that runs purely on ssd 
THIS runs very very very fast. i only store mediafiles on the harddrive but all the virtual machines and all the caching, temp files, metadata etc run either in ram or on ssd
