Second report shows typical short delays in EQ (< 3 sec, contrary to summary) caused by class loading while "Parsing & Indexing Loop" thread is active (i.e. heavy I/O in FileInput/OutputStream). First report shows similar minor class loading, though the parser appears inactive; perhaps other system I/O (no comment supplied).
