High CPU utilization

Classic Servoy
1

Hi All,

The servoy webclient solution is running in the application server . When I am running two clients and loading a set of records . The CPU utilization becomes nearly 100 % . It seems to be very high .

Server Specifications :

JVM Information
java.vm.name=Java HotSpot™ 64-Bit Server VM
java.version=1.7.0_04
java.vm.info=mixed mode
java.vm.vendor=Oracle Corporation

Operating System Information
os.name=Windows Server 2008
os.version=6.0
os.arch=amd64

Processor: Intel(R) Xeon CPU E5645 @ 2.40GHz
Installed memory (RAM): 3.75 GB
System Type: 64-bit Operating System

Windows Server 2008 R2 Datacenter

System Information
Heap Space Memory: allocated=322748K, used=136663K, max=1267072K
Non-Heap Space Memory: allocated=95680K, used=95074K, max=180224

We are getting the CPU alarms for that. It has placed our project in a great difficulty.
Please provide your suggestions on this.

Thanks,
Ashutos.

Can you explain what your solution is doing exactly when you get the high cpu usage?

Perhaps you were loading a foundset from a sql server db table with 1024 columns and each column is of type varchar and each entry is 8000 bytes? That could cause this problem.
