>Description:
3 servers (same kernel config and release) connected via a gigabit switch are producing terribly latencies which make the web/database servers unusable.

192.168.10.2 is a DB server but the traceroute shows incredibly latencies:

This happened when upgrading from 6.2-Pre release to 6.2-RELEASE. All servers are affected.
>How-To-Repeat:
Reboot the server and do mtr (mytraceroute) to 192.168.10.2, which is 1 hop away.
>Fix:
Rollback to 6.3-PRE RELEASE? This there a CVS tag for this??

Responsible-Changed-Why:  
This seems like a networking issue, assign it to the networking team. 
Submitter: Please be informed that there had been discussion on the 
bce driver recently (I cannot recall whether that went about performance 
issues though), if you are not aware of that please review the mailinglist 
archives of -net (as far as i can recall)

 This should not be a problem in more modern releases (7.0+).

State-Changed-Why:  
bce(4) received a lot of improvement since 6.2-RELEASE. 
Is it still issue on more recent FreeBSD releases? 
(e.g. 8.1-RELEASE or 7.3-RELEASE)

Close, submitter has no longer access to the hardware. 
I believe this was fixed long time ago.
