grixm Posted January 13 Share Posted January 13 Hi. For my application it would be very advantageous to speed up the boot time of the device as much as possible. The application depends on the network, and unfortunately it seems it takes a while for the interface to establish a connection. After plugging in the device, I count that it takes about 25-30 seconds until my application starts (which is set to start on reboot by cron). However, at that time, the network is still not up, so it matters little that the application has started. It takes another 20 seconds or so until the device is reachable by the network. So total 45-50 seconds from boot. Why is this? I see in systemd-analyze that NetworkManager.service starts at around 30 seconds, same as cron. So what is the holdup? The IP is static and it is plugged in with Ethernet, so I don't understand what takes time when it comes to connecting to the network, after the network manager has started. How can I troubleshoot this or make it connect faster? Bonus question. Another thing that takes a lot of time in the boot is armbian-ramlog.service, at nearly 8 seconds long. See attachment for full boot chart. Is there a way to shorten this too, without disabling ram logging entirely? bootanalyze.svg 0 Quote Link to comment Share on other sites More sharing options...
