Hi Joe, > Were you not testing a 5MB zip with SOAP serialization?
Yes. >Why use a 100MB zip with RMI? Well I only posted some of the highlights, I should have included the RMI 5M test in that block. Case: 5M zip byte[] over 1000 calls: Product Memory(ave per call) Time(ave round trip) AXIS no attachment 70M(160M peak) 2166.44/ms Java RMI 21M(62M peak) 203.53/ms As far as I understand AXIS uses an interop form of XML Serialization for Objects and RMI uses Object serialization. The reason for testing RMI was to try and isolate/prove the problem, many people have stated problems with parsing large XML documents regarding to memory and this is why processing large SOAP envelops consume so much memory. RMI does not parse XML nor does it use XML to transfer/serialize Objects. My main goal is to support the transfer of large(100M) zip files when I could not get the test to successfully complete using AXIS(no attachment) I tried RMI and it worked. Cheers, Greg
