I can illustrate the difference between QTime and the actual transaction
time by showing you the log entries from the application that correspond
exactly to the Solr log entries I shared:

INFO  - 2013-09-27 08:27:00.815; chain.c: Insert done, 66, time = 315
INFO  - 2013-09-27 08:27:01.976; chain.c: Commit done, time = 1161

The add request with 66 documents had a QTime of 181, but took 315
milliseconds.  The commit had a QTime of 1065, but actually took 1161
milliseconds.

Thanks,
Shawn
