So w= e had valid and a hughe amount of data. I did some tests, and discovered th= at a request that took about 1second on axis1.4 now takes up to 10 seconds = - (the processing of my own code takes about 300ms). I tuned all logging st= uff on and discovered that the xml generation takes ALOT of time. The retur= ned object holds a list of about 3000 objects with each holding some string= s and 2 other objects holding 2strings and 1 int. I serialized the Whole response to get an idea how big the response is. Thi= s way it say it=B4s 300kb. The server and the client run on the same machine (faster) or on different = machines (slightly slower, still a 1gbit connection). So the 300kb should b= e no problem - even if the XML overhead is 5 time as big as the data... Funny is, that Axis2 1.5 takes like 3 times longer than Axis2 1.4.1 does. B= ut both performances are not really acceptable. Especially because axis2 is= MEANT to be faster when it comes to bigger datasets. Did anyone else have these problems and can help me out? Some info that might be of any interest: Running 5 services simultanously, where all oft hem use the same libaries o= f different versions (or the same). (Axis2 webpage sais this should be fine= ) Running tomcat version 6.0 No additional Modules installed. No other servlets running. It=B4s not that axis is WATING when i request some lists, i can see the cpu= working in taskmanager. I reinstalled tomcat I redeployed axis2 1.5/1.4.1 I tried to work with 1 service only. I had a look if MTOM is turned on. I tried with java and C# client. If i forgot to mention something important, please ask me! Have you generated code with the WSDL (contract first) if so what is the databinding framework you have used? or use the java classes (POJO) to generate the service? thanks, Amila. Hm, serverside i let the service generatet he WSDL out of my own Classes. Clientside i just built a simple stub using ADB. From what i can tell the serialisation of my own Objects into SOAP ist he bottleneck. Greetings, mike; ALL help is greatly appreciated!
