Axis performance

[Tim McClarren <ti...@nominum.com>]

We are trying to use Axis beta 3 for a project that involves 
transmission of considerable amounts of stuff over the wire.

It takes ~ 90 seconds to transfer a Collection of 1000 simple objects 
over the wire.

Using RMI tunneled through HTTP, it takes only 2-4 seconds.

Is there something we can do to improve the performance?

  Turn the objects into an XML file, compress it, and then send it?

  Or, if you just turn it into an array of simple objects, it may go
faster.

I'm guessing it's because transfering verbose xml messages (like AXIS 
does) over the wire is slow.  I thought I remembered someone talking 
about compressing the data before it gets sent (in both directions then 
decompressing it on the other side).  Can anyone point me in a direction 
that I can learn how to do that?

Thanks,
David

you could help find those perf bottlenecks. I've heard claims that Axis
doesnt cache factorys for serialisers/deserialisers, which could be an
issue. Sam Ruby is busy tuning Axis this week, so try a nightly build, too.

While I was browsing the Axis API I found something that might be of
interest to you to achieve a better performance.
If you are sending the type attributes for each element in your SOAP
message switch that off. However, than your client has to find out about
the types by some other source. Maybe you want to use WSDL. Or you can
hardcode it using an explicit type setting.

To turn the SEND_TYPE_ATTR off one should use this
call.setProperty(Call.SEND_TYPE_ATTR, Boolean.FALSE);
However it didn't work for me, but you can have a try.


What should happen?
In the SOAP message:
<userID xsi:type="xsd:string">tomz</userID>
should turn to
<userID>tomz</userID>
= 50% less data to transmit (at least in this case)

So long
Tom



AXIS properties:
     SEND_TYPE_ATTR - Should we send the XSI type attributes
(true/false)
