The above is box A, which supports 5 DMs quickly.

This is box B, which supports one or two DMs slowly. What does the swap
and free memory say about these boxes?
All of the remote DMs are View-Only. Box B has one remote DM dedicated to a
particular PC, all others are for whatever PC gets there first.
.....
Items from Warren Brown's note:
"Another thing to check is the network topology. You don't mention if one of
the AW's is behind
an LI ?" ... ( Sorry, what's an LI? )
"One interesting thing to test is to do a 'glof'
/opt/fox/bin/tools/glof Control_Point (one that is on the display)
on both AW's and see if both take approximately the same time to respond
?"... ( Both boxes respond very quickly finding letterbugs and process
locations; I'm not sure how to ask for a "Control Point" do you mean
Compound:Block.Parameter ?)
Thank you again,
Sue

Can you list the /usr/fox/customer/hi/dmcfg file(s)?
Can be that not all DM are "view-only" which are by nature slower than
"operator class" dm's. I have see nproblems with this in the past with
symptoms similar to what you describe.
Idle time is not the only important value. available swapspace etc can =
be of
importance. Can you provide a few lines of vmstat 5 from both systems =
maybe?

I have two AW51B units, both at 170 mHz, version 4.3, who support old =

display managers using Exceed to supply view-only displays to PCs on =
our
plant network.
Box A supports 5 remote DMs and has a display call up time of about 1 =

time.
Box B supports 1 or 2 remote DMs and can take up to 5 seconds to brings =
up a
display on a PC. This box has 96 meg of RAM. Vmstat usually shows =
95-99%
idle time.
Taking the le1 (2nd Ethernet connection)down and then putting it back =
on
makes no change in the display call up speed. Neither box seems to =

time hogging processes running when ps -eaf is checked.=20
What else can I check? I'd like to get box B to perform like box A.
Thank you for your help.
