Title: Axis Performance problem

I am no expert Michael but have you tried pinpointing the exact piece of code that is taking up all of the time? You could try logging the system time at intervals in your code and from there gradually find the exact statement that is taking so long.  If you are still unsure why that statement should be so slow then you could ask the group again giving specifics about the statement/code that is slow.

 

Also, is the code slow on every invocation or just on the first execution after deployment - if it is the latter than this tends to be normal.

 

Also, are you using DOM or SAX for your XML work - SAX would be better as it is more efficient and does not load the entire document into memory prior to doing anything with it like DOM does.

 

Just some thoughts...

Subject: Axis Performance problem

I am sending out an array of custom type, when the array is longer then say 20 members the performance of the axis implemented service just crawls to an eventual completion around 30 sec.  The db side of the service takes around 2 sec at the worst and the rest I guess is writing to xml.  I was under impression that writing to xml should not be that time consuming.

The objects which make up the array are very straight forward
Consisting of about 10 strings and 5 decimals.

The method in question only takes one parameter and returns the array.  I am using the latest release of axis, tomcat, jdk1.4. xercesImpl-2.0.2.jar.

Is there something I am completely missing or doing very wrong, because I just can't imagine what axis could be doing for that long.

Thanks in advance.
