If you have performance issue, I suggest that you look at vtd-xml (http://vtd-xml.sf.net)

As of this change we also switched parts = of our database schema, and so we dind=B4t test performance until now. I wr= ote a DB transformer that created the new database out of the old one. 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! ALL help is greatly appreciated! Greetings Mike Adelmann;
