Its a surprise to me that log file sync should be affected by the size of the process table, rather than the number of active processes (or private redo strands presumably?)

Other than the usual minimal memory overheads, there is significant impact on

  1. Log File Sync Wait times
  2. Calculated Value of MBRC

Starting from 10gR2, MBRC is auto tuned. The value of processes is taken in to consideration (along with buffer cache,etc) while calculating the MBRC. So I would exercise caution while playing with these parameters.
