Re: Linux Network Performance Slower Than NT, please help

[Marco Shaw]

1)  You've patched W2K to the latest SP1, but have not done the same with RH?  2.2.16 has been out for some time, and 2.2.17 rpms are starting to appear.  2)  I consider this a 'blessing', but you have 2x, even 3x more RAM for W2K. 3)  Your testing is already blurred because of the different architectures.   Marco   PS  Apologies, but this message looks like it'll go through as HTML... ----- Original Message ----- From: Ed Lazor To: [EMAIL PROTECTED] Sent: Thursday, November 02, 2000 3:01 PM Subject: Linux Network Performance Slower Than NT, please help Hi =)  I setup a small network and did some testing to discover I'm not achieving maximum network performance.  The bottleneck appears in ftp'ing files with the RedHat server.  Any ideas on how to improve performance? To test the computers involved, I've tried different configurations and approaches.  I've included as much information as possible.  I tested using different network cables to eliminate this as the source of the problem.
