[FX.php List] Web traffic versus native FileMaker use

Thx for your input.

My online system performs perfectly for a good part of the day.  I 
have some pretty extensive logging and use one particular frequent 
operation as a baseline. It takes 0.1 second each time. This rules 
out problems with the web operation.  On the other hand, I can 
confirm that the native FileMaker system has tons of calculated 
summary fields and filtered portals...the kind that you have to sit 
and wait for....under the domain of a different developer.  So, it is 
safe to conclude that the native system bogs down under load.

That being established, the question is how much can I expect from 
the online system if the native system has these issues?  Throwing 
big iron at it (2 machine deployment) didn't solve the problem. The 
degradation is a sudden one from baseline 0.1 seconds to 30 seconds 
for a couple of minutes and then back down again.  All the while, the 
Windows Task manager practically shows a picture of the machine 

It could be sorting. It could be a script. It could be summarizing in 
native mode....or all three. I have no control over any of these.

It looks like I'm talking myself into a new piece of hardware. ;-)
