Performance issue on big data

[Stephane Lecercle]

Hi,   I am using Axis 1.1, and I have noticed on a stress test that there is an issue when I am trying to send and retrieve from a Java client big binary data, if this data is a member of a structure. Indeed, if I am using a method of this kind :   byte[] exchangeData (byte[] buffer);   the performances are very good.   But if I am using a method such as :   ReturnValue exchangeData2 (byte[] buffer);   with ReturnValue as :   class ReturnValue {     public byte[] bufferOut;     public int status; }   The performance is awful, as soon as the bufferOut member size is up to around 2000 octets.   Has someone noticed the same problem ? Is there anything to tune (such as the serializer/deserializer) on Axis ? Many thanks,     Stephane LECERCLE.
