When we connect to our AS400 via screen surfer the sessions 
are extremely slow yet on the PC that is acting as the 
server it is fast. How can we speed it up?

If what you are describing is the initial connection to the 
system, you need to add a TECONNECTED tag to one of your 
template files.

This will reduce the connection time down from 5 seconds to 
the actual connect time.  The syntax for TECONNECTED is:

<TECONNECTED When Screen_row_col is "text">

Row= the row that "text" appears on the initial screen
col= the column that "text" appears on the initial screen
"text" the text that is being tested for for initial
       screen display--try to make it low in the screen
       in case the initial screen is produced from multiple
       buffer writes from the host

If the extremely slow speeds are experienced at other times, 
there may be a screen transition error occurring that we 
could diagnose for you.

What is the connection speed between you and the 
Screensurfer server?

Please could you see if there is a screen transistion 
error?  Log files are about to be mailed.

The workstation is connected directly to the network, which 
is 100Mbps.

First, the connection can be quicker with a TECONNECTED--the 
real problem is in the auto-sync script.

We have identified a problem with threading in certain 
browsers, whereby the threads get crossed and a refresh 
"echo" occurs.

Do you have IE5.5 as the browser?  A fix has been 
determined, but I need to check at the office whether it is 
in the current build.  I will update in 2 hours or so.

Meanwhile, turning-off autosync will fix this particular 
problem.

In registry--HKEY_LOCAL_MACHINE/Software/Intelligent 
Environments/Screensurfer/Config:SynchType, change to 0 
(zero), restart Screensurfer and the refresh echo will go 
away (but, for connections with fluky host buffers, you will 
then need to manually refresh screens in passthrough mode 
that haven't had some scripting wrapped around them to 
handle odd transitions...normally only needed in logon 
sequences).

OK--new build to try (please with the synchtype=2 in 
registry to see if it fixes the refresh echo)--

Thank you for this.  I have forwarded it to the evaluator.

At the same time he replied to the earlier suggestions 
saying just "Still isn't any faster."  I mailed immediately 
asking what had been tried - TECONNECTED or synctype 0 - 
but have not yet had a reply.

The log definitely showed a serious sync echo 
occurring--maybe after updating the registry he didn't stop 
and restart SS, which I forgot to mention as a necessity.
