Sending a SIGKILL (kill -9) is not recommended.Miner spora rate: 1546 h/sand logs -miner_sporas_per_second. Note that it is 0 when you start the miner without data and slowly increases as more data is synchronized. After the number stabilizes, you can input it into the mining calculator generously created by the community member @tiamat here to see the expected return.randomx-benchmark script../bin/randomx-benchmark --mine --init 32 --threads 32 --jit --largePages. Replace 32 with the number of CPU threads. Note that reducing the number of threads might improve the outcome. Do not specify --largePages if you have not configured them yet. For the reference, a 32-threads AMD Ryzen 3950x can do about 10000 h/s, a 32-threads AMD EPYC 7502P - 24000 h/s, a 12-threads Intel Xeon E-2276G CPU - 2500 h/s, a 2-threads Intel Xeon CPU E5-2650 machine in the cloud - 600 h/s.hdparm -t /dev/sda.

For example, a 12-core Intel Xeon with a 1 GiB/s SSD with a third of the weave is capped at 540 h/s. In practice, the performance is usually about 0.7 - 0.9 of the upper limit.stage_one_hashing_threads (between 1 and the number of CPU threads), stage_two_hashing_threads , io_threads, randomx_bulk_hashing_iterations. For example,recall bytes computed/s should be roughly equal to Miner spora rate divided by your share of the weave. If it is not, consider increasing io_threads and decreasingstage_one_hashing_threads. You can learn the share of the weave the node has synced to date by dividing the size of the chunk_storage folder (du -sh /path/to/data/dir/chunk_storage) by the total weave size. Increasing randomx_bulk_hashing_iterations to 128 or bigger might make a big difference on the powerful machine.chunk_storage and rocksdb folders, the node will fill it up, and your miner may nevertheless be competitive, assuming the disk and the processor are sufficiently performant.sync_jobs configuration parameter like this:mine flag) to further speed up syncing.cat /proc/meminfo | grep HugePages. To set a value, run sudo sysctl -w vm.nr_hugepages=1000. To make the configuration survive reboots, create /etc/sysctl.d/local.conf and put vm.nr_hugepages=1000 there.cat /proc/meminfo | grep HugePages should then look like this:

You can obtain your public IP here, or by running curl ifconfig.me/ip. If you specified a different port when starting the miner, replace "1984" anywhere in these instructions with your port. If you can not access the node, you need to set up TCP port forwarding for incoming HTTP requests to your Internet IP address on port 1984 to the selected port on your mining machine. For more details on how to set up port forwarding, consult your ISP or cloud provider.data_dir folder to the new machine. Note that the chunk_storage folder contains sparse files, so copying them the usual way will take a lot of time and the size of the destination folder will be too large. To copy this folder, use rsync with the -aS flags or archive it via tar -Scf before copying.=ERROR REPORT====...=== Socket connection error: exit badarg, [{gen_tcp,connect,4, [{file,"gen_tcp.erl"},{line,149}]}TCP/IP failed to establish an outgoing connection because the selected local endpoint was recently used to connect to the same remote endpoint. This error typically occurs when outgoing connections are opened and closed at a high rate, causing all available local ports to be used and forcing TCP/IP to reuse a local port for an outgoing connection. To minimize the risk of data corruption, the TCP/IP standard requires a minimum time period to elapse between successive connections from a given local endpoint to a given remote endpoint.
