<https://i.imgur.com/9lHpIfz.png> Hello,
I am experimenting with send (from socket to socket through a loopback). I create a flamegraph for that and measure time of execution. It seems that is takes relatively much time. (I am not sure whether is it much or not). In test I send a 64-byte message in a loop. send function takes 10-15 microseconds. 1. Is it much or not? 2. Have you any idea how to improve it? I tried to extend send buffer socket, doesn't help- I know that probably it couldn't help. 3. When it comes to a flamegraph: It looks like the kernel waits for a response- I mean the function ip_recv and so on. What does the kernel try to receive? AFAIK a send function doesn't wait for ACK from receiver. -- You received this message because you are subscribed to the Google Groups "mechanical-sympathy" group.
