Subject [jira] Created: (DERBY-3791) Excessive memory usage when fetching small Clobs
Date Tue, 22 Jul 2008 08:54:32 GMT
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.
