[mdb-dev] [PATCH] optimize the scan for next data page

[David M. <mdb...@dm...>]

The scan for the next data page for a table starts again from the 
beginning each time.  For really large tables this causes a noticable slow 
down as we get further and further into the data.

This patch uses the table->cur_phys_pg variable to initialize the starting 
point of the scan to exactly the place we left off last time.  This saves 
about 30% cpu time for some exports here.
