Seeking Advice: Slow Bitcoin Blockchain Synchronization on Raspberry Pi Node

Hello everyone,

I recently set up a Bitcoin node on my Raspberry Pi. It's been about 15 days, and the synchronization of the Bitcoin blockchain is still only at 27%. I have the node's local address pointing to my router, and I'm using a fiber connection with a speed of 70 Mbps.

I'm starting to wonder if there might be something throttling the node. Is there any way I could speed up this synchronization process? For context, I recall the sync being significantly faster when I was using Umbrel. I'm concerned I may be doing something wrong.

Any advice or suggestions would be greatly appreciated. Thanks in advance!
