Re: 20050621: LDM performance with FC3

Tom,

Thanks for the quick response.  Here's the answers:

1) 1Gb RAM
2) 2Gb swap
3) Queue size is now 2Gb, _but_ up until yesterday it was the default 
400Mb, so I don't think that's the problem.  I'll decrease it down to 
800 or so, to make it smaller than memory (didn't realize that could be 
an issue).
4) Frequent connecting and disconnecting is most likely me (in the past 
week or two) and/or Karl stopping and starting - we're doing it a lot, 
trying to get a handle on this issue, to see if it really is the LDM 
that is causing the problems, or is simply making the problem manifest 
itself.

Feel free if you'd like to log in - through gate.comet.ucar.edu, then 
from there you can rlogin to oneu1 as you...  I'll give you sudo privs 
if you like, so you can log in as "ldm" (I don't remember the password)

Thanks for the quick response - our new servers are 64 bit and we're 
trying to expediate their installation - waiting for rack hardware right 
now...

Comment:  the COMET machine apparently had a conflict in its setup for
its primary Ethernet interface.  Tim and another COMET system admin
were working on reconfiguring the interfaces on Friday, June 24.

I wanted to follow up on this after speaking with Tom last week.

Karl found our problem - the machine was set up for "half-duplex"
networking apparently.  I guess that means 1/2 as fast... I can't really
explain it, but I'm sure Mike can...

We're up and running normally now.

Thanks for your time Tom!
