#AskNostr let's hear your opinions about this exasperating IBD process I'm going through with Bitcoin Core on Ubuntu.
As I mentioned, this is a laptop with an i7 7th gen 3.7 GHz processor, 8 Gb memory, and I've set my data folder and blocks folder to an external SSD (on a USB 3.0 port). I completely nuked the laptop's disk and did a 100% fresh exclusive install of Ubuntu 22.04. Nothing else on this computer other than the cleanly installed OS.
I don't know much about anything, but what I can see on my system monitor is:
- CPU cores working at 10-20%
- Memory working at 40%
- Swap working full capacity, at 100%
- Network working at laughable bandwidth
Interestingly, the network monitor shows bursts of incoming data coinciding with bursts of CPU work (50-60%). Paired with the 100% swap effort, I conclude that's the bottleneck. Am I onto something here?
In the Bitcoin Core options, I set the size of the database cache to 1000 vs the default 300 (or was it 450? can't recall). Is there any point to further tweaking it?

quoting nevent1q…khxnFresh Ubuntu 22.04 on a laptop that's a lot newer than that, with an i7 processor (7th gen) and 8 Gb memory. None of the cores is working beyond 20%. Memory usage is around 40%.
Swap is at 99.8%, 2.1 Gb out of 2.1 Gb?
Is this the bottleneck? I've no idea.
