Loading of pictures is very faster now, in rt2_demo it is quick, so in normal desktop environment it is quite perfect. I found that increasing sendspace & rscvspace for tcp in sysctl.conf did not change anything, and my thought is that it's got something to be with udp/tcp. Any thoughts on what could affect X performance so much with tcp ? Did I misconfigured something ?
