------- TL;DR ------- Performance seems slow (around 300-400Mbit peak). How to improve?
------- The Long Version ------- I tried to test tinc performance for an upcoming project that may need to use NFS over a VPN. Our current tinc network seems to be able to transmit at around 30-40 MB/s. (I used an 1GB random testfile to copy to/from /dev/shm/; using netcat and http.) In comparison, HTTP and scp are 300MB/s and 200MB/s respectively (over 10Gb link; over 1Gb link, both are around 112MB/s). By observing _top_ output, it seems that the CPU usage is around 90% for the tinc process on at least one of the transmitting machines. I tried to change the cipher to aes-128-cbc, but it did not have any significant effect on transmit speed. How can I know tinc operation eats up my CPU? Are there any simple best practices to achieve better performance? Thanks in advance: PP P.s.: With regards to my memory problems last month: since then, I have no problems with memory usage at all: usage remains constantly under 10MB per daemon. CNR. :( _______________________________________________ tinc mailing list tinc@tinc-vpn.org https://www.tinc-vpn.org/cgi-bin/mailman/listinfo/tinc
