OCI consumes a lot of CPU with Oracle 220.127.116.11, not seen this on previous releases.The OCI release session can take up to a minute to release the sessions, when using session pooling.
Testcase using OCI session pooling:
With expired time < timeout, the time to release sessions is zero. After that the release time is approximately equal to the timeout, and this is true for all other timeouts tested: 20, 5 and 0 seconds, so a quick workaround is simply to set the timeout to zero.
