Good to know! - this was a silly error - When a consumer got so far
behind a producer so that the cache was invalidated, after every
acknowledgement of a message, a cursor would check to see if the index
was empty. To do that it would ask for a count of still outstanding
persistent messages. For a BTreeIndex - a count resulted in every
BTreeNode been paged into memory in the same transaction to be
counted. Its remarkable KahaDB was as fast as it was under the
circumstances :)

Hi Daniel,

thanks for the validation.

Any eta on the 5.4-snapshot? (
https://repository.apache.org/content/repositories/snapshots/org/apache/activemq/apache-activemq/5.4-SNAPSHOT/still
lists the build date as 1/20) Once it's out, I'll give it a run
through.

Thanks Daniel! Though please wait for the next valid 5.4 build -
looks
like its missing a dependency at the moment
