Hello! 
 Recently I used SOAP transmit the data between two isomerism  systems, the SOAP 
client used Delphi 2005 write, the server end used Apache AXIS 1.2.1.  The client 
end and the server end  exchange data work well, but the performance aspect meets 
one  question.  
  The Delphi client end parse the Soap data package of  data is specially slow, 
specially when analysis object array.  If the  array length in 500, the delphi 
analysis speed lets the person endure  with difficulty. But when I completely 
changes to AXIS realization,  in performance is very good.  
  Under is my test result:


complex object detail is follow:

1     TAddress = class(TBaseObject)

========================================================================

using AXIS both server and client, the result is follow:

array length 100 ,Invoke time 2078 ms
array length 200 ,Invoke time 1937 ms
array length 300 ,Invoke time 2015 ms
array length 400 ,Invoke time 2094 ms

array length 2300 ,Invoke time 12156 ms
array length 2400 ,Invoke time 13000 ms
array length 2500 ,Invoke time 13516 ms


but when I change client using delphi 2005,when array length is about 500, invoking time  > 30s.
