The Streams capture process is observed to be running extremely slowly in 10.1 and 10.2 Streams.  An AWR report reveals that the top wait event for the instance is 'CPU time'.  When investigating the SQL that is the biggest contributor to the CPU time, execution of a procedure called SYS.LOGMNR_GTLO3 is the top contributor to both CPU time and elapsed time.
