--part1_11f.6aa9f9e.29164760_boundary Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Hello, I am having a problem with FreeBSD4.4-STABLE-10.29.2001 network performance. I am using Netgear FA-312 network adapters in all machines with a NDC Communications NSH510 5 port switch. Three machines are running FreeBSD. All FreeBSD machines are running the same version. There are two Windows computers running Win98SE. All network connections are 100mbit full-duplex as stated by ifconfig and windows and the switch. Problem: FTP or NFS file transfers between any of the three FBSD machines with file sizes say >60KB, the connection slows to a crawl and stops. FTP file transfers between the Win98 machines and FBSD machines have the same problem. But, using file transfers between the two Win98 machines, file transfer throughput is in the 10-12 MegaByte/sec range. Note that I did not start having this problem before I upgraded the FBSD machines to 4.4-STABLE from 4.2STABLE. I have submitted a bug report to GNATS, but it was closed stating that it is a config problem between the NICs and the switch on my end. How can it be a config problem on my end when the only thing that has changed is the software load on the FBSD machines? Also, if the config theory is true, then how does one account for the fact that the Windows machines don't have this problem? I have even rotated cables and ports and the problem stays with the three FBSD machines. The only fix that I have found so far is to set the network adapters to half-duplex mode. Any suggestions before I resubmit a GNATS problem report? Dan. --part1_11f.6aa9f9e.29164760_boundary Content-Type: text/html; charset="US-ASCII" Content-Transfer-Encoding: 7bit <HTML><FONT FACE=arial,helvetica><FONT SIZE=2>Hello, <BR> <BR>I am having a problem with FreeBSD4.4-STABLE-10.29.2001 network performance.
