It causing the CPU Utilization in the range of *80-85 %.* When we tried jst returning back from the Method with Null response Our CPU Utilization is in the range of 45-50% We are using the axis2 webservice in it. | %1,3% *Hardware Configuration* | | %4% Application Node | *No of CPU* | *8* | | CPU Type | Intel(R) Xeon(R) CPU E5530 @ 2.40GHz, cache size 8192 KB | | *Memory* | *8 GB* | | Network Card | 100 mbps Ethernet | | %4% Database server | No of CPU | 8 | | CPU Type | Intel(R) Xeon(R) CPU E5620 @ 2.40GHz, cache size 12228 KB | | Memory | 160 GB | | Network Card | 100 mbps Ethernet | So currently we are struggling to reduce the CPU usage. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/734192#734192] Start a new discussion in Performance Tuning at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2078]
