I have a test bench with a FBSD gateway with 1 Nic card. No user ppp or firewall. Very simple. Nothing else running. The Nic card is connected to a Winbox with a crossover cable. Some times the response time on the Winbox is almost instantaneous and other times it's about one quarter the speed. The slowness is so obvious that I started taking bench marks. Using telnet on the Winbox to the FBSD server, some times I have to wait for the login screen to appear and when entering the user id some time the letters take 2 or 3 seconds to appear. After getting logged in I edit a file and using the arrow button to scroll down the screen hesitates a lot. Other time the speed is as if I am editing from FBSD console. I needed some real numbers to compare speed so I started using FTP Lite on the Winbox to download a file from FBSD /usr/home/userid/dmesg.boot. I put this file there to have a test file. All the speed tests start off with booting the FBSD gateway box followed by booting the Winbox. I then fire up FTP and download the test file dmesg.boot. One test I got results of 15.3 to 15.7 duration times with 72.40 to 72.98 KBps transfer rates. I got a tightly packed group of results doing the same download file 15 times. I shutdown both machines and redo the same test and I get FTP results of 30.3 to 40.7 duration times with 30.7.40 to 36.48 KBps transfer rates. Now I would think using machines that are basically doing nothing except this single task should have repeatable very fast download times no matter how many times the hardware in booted. I checked the Nic cards in both machines, there set at 100baseT Full duplex. I have dialed in to my ISP and have better FTP results than this over the internet. Does FBSD have a problem with crossover cables? Any ideas? To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
