-/* These all interelate for performance.
-**
-** If the journal block count is smaller than n transactions, you lose speed.
-** I don't know what n is yet, I'm guessing 8-16.
-**
-** typical transaction size depends on the application, how often fsync is
-** called, and how many metadata blocks you dirty in a 30 second period.
-** The more small files (<16k) you use, the larger your transactions will
-** be.
-**
-** If your journal fills faster than dirty buffers get flushed to disk, it must flush them before allowing the journal
-** to wrap, which slows things down. If you need high speed meta data updates, the journal should be big enough
-** to prevent wrapping before dirty meta blocks get to disk.
-**
-** If the batch max is smaller than the transaction max, you'll waste space at the end of the journal
-** because journal_end sets the next transaction to start at 0 if the next transaction has any chance of wrapping.
-**
-** The large the batch max age, the better the speed, and the more meta data changes you'll lose after a crash.
