Re: Axis2 Client performance issue - AxisConfiguration Caching
In our case, both the parameters don't change at all so I made it into a class variable. I am not sure whether it is multi-thread safe but should be ok since it is a read-only object tree. If the parameters do change just use the tuple (path, axis2xml) as key and ConfigurationContext as the key value.

Re: Axis2 Client performance issue - AxisConfiguration Caching
without knowing all entailed ( and thus the reason I was asking why axis2 didnt attempt to do this) I'd guess solving that problem with something like: ConfigurationContext config = ConfigurationContextFactory.getCachedConfiguration( String differentParameter ) would be a problem worth understanding and solving to get this performance/memory management for all axis2 users was my only point. How varied that parameter set can be I guess is more the question, but when people are calling: ConfigurationContextFactory.createConfigurationContextFromFileSystem(getAxis2RepositoryPath(), getAxis2ConfigFileLocation()); (in a "usual" config situation) If nothing else, putting this functionality into some sort of base axis 2 client would be a huge gain. On a side note, we noticed the same sort of issues when "hotdeploy" was enabled. On the server side, is it doing the same thing? We're seeing the same issues, with degraded performance and seeming to leak memory? - Original Message From: Michele Mazzucco <[EMAIL PROTECTED]> To: axis-user@ws.apache.org Sent: Wednesday, March 7, 2007 9:45:09 AM Subject: Re: Axis2 Client performance issue - AxisConfiguration Caching Sean, how could the factory cache a previously created instance since you can use different parameters for different calls?

Sean, how could the factory cache a previously created instance since you can use different parameters for different calls?

Ok, I'll do that for us ;) If this isnt added to the next release, hopefully everyone who uses axis2 as a client reads this and gets the benefit of OOM better performance and elminating a pervasive memory leak problem. - Original Message From: Davanum Srinivas <[EMAIL PROTECTED]> To: axis-user@ws.apache.org Sent: Tuesday, March 6, 2007 6:32:42 PM Subject: Re: Axis2 Client performance issue - AxisConfiguration Caching You can cache configContext itself! -- dims On 3/6/07, sean curtis <[EMAIL PROTECTED]> wrote: > When running some recent tests against our webserver that contains our client > code, it seems that the client causes a huge bottleneck in performance. > Perhaps we have it configured incorrectly, but doing some initial looking at > the source code, the question came up: > > When using the following code: > > ConfigurationContext configContext = > ConfigurationContextFactory.createConfigurationContextFromFileSystem(getAxis2RepositoryPath(), > getAxis2ConfigFileLocation()); > > does this actually cause a re-parse, reconfigure of the axis2.xml file on > each call?

Re: Axis2 Client performance issue - AxisConfiguration Caching
Curtis, I faced the same problem. It also leaks around 250KB per call. Though I couldn't figure out the root set that is holding references to a lot of OMElementImpl and OMTextImpl objects. The JVM was also crashing every few days. Change the code generated to cache the ConfigurationContext and the performance+memory leak disappears. In a local loopback test the time taken to answer a request went down from 1.5s to around 20~50ms.
