Review latest Array indexing performance numbers

Cihan,

Can you please review the latest array indexing numbers in show fast?

Here's the summary:
Query KPI Measured
Q2(ok) 13000 13688
Q2(false) 700 6327
Q3(ok) 1700 1421
Q3(false) 428 636

A few things to note:
1. Q2(stale=false) number seems too good to be true.
2. Q3(stale=ok) is below KPI.

Here are all the logs:
Q2(stale=false): http://perf.jenkins.couchbase.com/job/hades/3405/
Q2(stale=ok): http://perf.jenkins.couchbase.com/job/hades/3408/
Q3(stale=false): http://perf.jenkins.couchbase.com/job/hades/3442/
Q3(stale=ok): http://perf.jenkins.couchbase.com/job/hades/3420/
