Description Toshiya Kobayashi 2012-11-30 09:55:17 UTC 
Description of problem:

In drools-camel-server, memory allocation during request/response message handling is quite larger than actual request/response size.

For example, with attached numbers.drl and JBoss_Benchmark_Request.xml, one SOAP request results in 45MB+ object allocation while the actual request size is 200KB and the response size is 650KB. They are short-lived objects so wouldn't be a memory leak but affect performance especially under high load.

They are likely String operations (e.g. byte array <-> String conversion). Probably they are required anyway. But I hope some memory conscious solution can be found.
