Hi Daniel,

There have been issues reported with CLOB performance on linux systems 
with 10.2.2.0.

Pls find more information here 
https://issues.apache.org/jira/browse/DERBY-2634

A small extract from the same issue

"For the next version of Derby (10.3) we are changing the way LOBs are 
sent between client and server.
The main purpose is to reduce the memory requirements when dealing with 
large LOBs,
but I think the performance should improve for some operations. The new 
code has been checked into the
development branch."

The issue actually says that the code is currently disabled. But it has 
been enabled now.
