Excessive memory usage when fetching small Clobs
------------------------------------------------
Key: DERBY-3791
URL: https://issues.apache.org/jira/browse/DERBY-3791
Project: Derby
Issue Type: Bug
Components: JDBC
Affects Versions: 10.4.1.3, 10.3.1.4, 10.2.2.0, 10.5.0.0
Reporter: Kristian Waagan
Assignee: Kristian Waagan
Priority: Minor
When investigating DERBY-3312 I found out that performance with the embedded
driver has decreased a lot as well.
Analysis on trunk indicate excessive memory usage, causing high allocation and
garbage collection costs.
I believe there was another major performance problem in 10.3, but it appears
fixed in trunk. I have not spent time identifying this problem.
