ce we know that the stall always seems to be 207ms, I'm pretty sure that actually it stalled 14 ms before that, and needed 14 ms to finish the complete burst in one direction. -- Carlo Wood

are WAY smaller. Obviously I have no idea if this is a problem with epoll itself, or that there is a problem with TCP/IP for this case. But I am not a kernel hacker, so all I could to was provide this little test case that allows you to reproduce it. -- Carlo Wood
