I don't know about you but I have had severe FTP download and browser access speed issues with the newer S.u.S.E releases. I have a 6.4 as a firewall and when NT was downloading a file or browsing the Internet through the firewall I got the speed I expected. However, if the download or browse was initiated from a S.u.S.E, either the firewall or a client, I got 1/4 the expected speed, stalls, timeouts, aborts, etc. I tried different NICs and different drivers to no avail. Since NT was not experiencing the slowdown I began to suspect the TCP implementation on S.u.S.E. After much research I came across the following resource: Pittsburgh Supercomputing Center (PSC), Carnegie Mellon University http://www.psc.edu/networking/perf_tune.html and the kernel docs on www.linuxhq.com. Lo, and behold, the information I found indicated that newer Linux kernels since have implemented different defaults for TCP/IP per RFC1323. One of these was setting tcp_timestamps TRUE. According to the performance pages from CM, one thing to do was to set these back to false. i.e.: echo 0 > /proc/sys/net/ipv4/tcp_timestamps Wow! What a difference in speed!!! Question: why isn't this info "front and center" at the S.u.S.E. web site?? Am I the only one who had this problem or am I the only one who took so long to figure it out.
