Re: [expert] Data Collision - How to improve transfer?
collisions occur when more than one nic "requests to send" . When the data rate is at 100 mb you will get more collisions because of the additional requests to send from ea. nic. when two nics experience a collision both back off a random number of millisecs and then again "request to send" enough theory... You might try a different nic manufacturer or may be try and replace one on the nic with a 10. Not many collisions should not occure with only two nics on a lan. The yellow lite may also be an indication of noise. if you have a sniffer you should have a look at packet errors it could be that you just have a bad nic. hope this helps terry - Original Message - From: Sevatio Octavio <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Wednesday, November 10, 1999 11:01 PM Subject: [expert] Data Collision - How to improve transfer? > I know this is not really a Linux issue but... > > I'm transferring data between my linbox and winbox.

The net here, all 100BT, runs virtually collision free and VERY fast. I am a switching hub addict...:-) Have you bert(sp?) tested all the connections? Regards Christopher Cox

[expert] Data Collision - How to improve transfer?
I know this is not really a Linux issue but... I'm transferring data between my linbox and winbox. Both are equipped with 10/100 NICs through a 10/100 hub. My max transfer rate stops around 600k/s and my hub's collision light stays on for the majority of the time during transfer. Is there any way to improve this transfer rate by cutting down the data collision? Seve
