I recently upgraded from 4.6.1 to 4.7.1 and have found that the DIH
process that we are using takes 4x as long to complete. The only odd
thing I notice is when I enable debug logging for the dataimporthandler
process, it appears that in the new version each sql query is resulting in
a new connection opened through jdbcdatasource (log:

the speed of running a full import?
This is most likely the problem you are experiencing:
https://issues.apache.org/jira/browse/SOLR-5954
The fix will be in the new 4.8 version. The release process for 4.8 is
underway right now. A second release candidate was required yesterday.
If no further problems are encountered, the release should be made
around the middle of next week. If problems are encountered, the
release will be delayed.
Here's something very important that has been mentioned before: Solr
4.8 will require Java 7. Previously, Java 6 was required. Java 7u55
(the current release from Oracle as I write this) is recommended as a
minimum.
If a 4.7.3 version is built, this is a fix that we should backport.
Thanks,
Shawn
