seems that the query time per second has increased about 10 times in the 4.1x version. In
the 4.0 version we also noticed that the size of the index used to around 14 GB but we noticed
this is now 7GB in the 4.1x release. So is the index compressed in 4.1? Can we turn off that
for performance improvement.

Interesting. It would be good to try and see if this slowdown is indeed due to the compression.
It's now the default and you can read more about it here:

If we can confirm that is indeed the issue, we should create a JIRA issue.

What are the details of the query load test you are doing?
