ReadOnly option was introduce with 2.4
from javadoc: "...as of 2.4, it's possible to open a read-only
IndexReader using one of the static open methods that accepts the
boolean readOnly parameter."

Alas, it's new as of 2.4. Can you upgrade?

Are you opening your IndexReader with readOnly=true? If not, you're
likely hitting contention on the "isDeleted" method.
When you run with a "normal" directory, either on a traditional hard
drive or SSD device, do you use NIOFSDirectory? That removes
contention, but, it only works on non-Windows
