tracker issue : CF-3711982

Duplicate ID:	CF-3695114

Problem Description:
I have a webservice running on Coldfusion 10 64bit. While investigating a memory leak I went to upgrade the JRE from 1.6 to 1.7 but noticed a significant performance hit. I had created a simple test webservice which on JRE 1.6 I could run easily at 5000 requests per minute as soon as I changed the JRE to 1.7 though this rate drops too 2000 or less per minute. 

Running Server JRE: java version "1.7.0_51" Java(TM) SE Runtime Environment (build 1.7.0_51-b13) Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

Steps to Reproduce:
Create webservice using files supplied. Create test request in SoapUI and load test through LoadUI. First test with JRE 1.6 then change JRE to 1.7.
test xml:
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:test="http://test">
   <soap:Header/>
   <soap:Body>
      <test:leakName>Test</test:leakName>
   </soap:Body>
</soap:Envelope>

Actual Result:
Results for JRE 1.6 are 5000+ request processed per minute.
Results for JRE 1.7 are 2100-2200 requests processed per minute.

Of course results will vary depending on computer and setup but these dramatic differences where found on all of our servers. Dev, Staging and Production.


Expected Result:
Same amount of requests processed per minute for both JRE 1.6 and JRE 1.7. Or at least close.


Any Workarounds:
Rollback to JRE 1.6
