Hello everyone
Gonna be fast...
I'm trying to download the Blockchain (by btc core) on an external HD, using my laptop (256 ssd, 8gb RAM). My internet connection is around 300mbps, and it is doing great, but the same way it keeps downloading 0,03% per hour... What can I do for optimizing this process ?? Just gotta download this and it won't work this by this speed.
Best regards
Follow these steps:
- get a laptop with at least i5/i7 CPU, 2GHz+
- install PCIe NVMe 4.0+, 2TB or larger
- install 64GB DDR4/3200+ memory
- install your favourite OS (Windows 11 or whatever)
- install all the updates etc., remove/stop bloatware
after you get the OS cleaned up:
- get the latest core from
https://bitcoincore.org/en/download/ - block all incoming connections (all protocols and ports)
- block all protocols for outgoing connections, except IPv4
- open TCP/UDP port 53 and 68 and TCP port 8333 outgoing connections (for bitcoin-qt only)
- block all other outgoing connections (all protocols remote ports, except 53,68,8333 above) for all other applications
- disable power management
If you use your router as a DNS, open 53&68 for that IP only.
With ~100 mbps Internet connection, T480 Thinkpad, I am getting ~25GB per hour blockchain downloads.
(Average utilization in my setup: CPU: 35%, Memory: 10%, Network: 10%, Disk: 2%)
