This sounds to me like Jellyfin is just transcoding your videos for your client(s) that don't support the files.
Transcoding is resource intensive. It will use up a lot of resources for a while.
If you click on the playback info in the video player while playing something, it will tell you what's happening.
On top, it will say the following:
Direct Playing == No transcoding
Direct Streaming == Either audio is being transcoded and/or a remux is happening
Transcoding == The video is being transcoded
This is normal. If you want to avoid transcoding:
1. Convert all your media to codecs that are supported on most clients
2. Use a player that can direct play more codecs
If you want to convert your media to another format that can direct play on most things, follow this:
Video: H264 8bit
Audio: 2.0 AAC
Subtitles: SRT
We normally say to set up a GPU for HWA. GPUs can transcode way faster than CPUs in most to all cases.
However, your DS1522+ does not have a CPU with an iGPU. All of Synology's current models that come with an AMD CPU lack any type of GPU, so you're forced to transcode on the CPU cores.
If you want to use a GPU, you're going to need to migrate away from your Synology and onto another system.
