CentOS 7 as a guest VM
Seems like its the single byte thing...
I tried adding:
int flag = 1;
if(setsockopt(fd, IPPROTO_TCP, TCP_NODELAY, &flag, sizeof(flag)) < 0)
but did not have any effect. I also did the echo 1 >
/proc/sys/net/ipv4/tcp_low_latency
seems to have no effect also.

CentOS 7 as a guest VM
I am experiencing an issue that my process does not wake out of a select()
call when a single character is received in an input file descriptor when
running as a VMware guest.
Anyone ever experienced this ?
I can run tshark and see the character arrive, but my process does not wake
up and see that character. Most times it works - but once in a while it
does not.
So I made a change on my code -
