| Description |
|
Largest amount of CPU time appears to be single byte copies in weBulkInsert() to messageIn. If we flip the array of table->rows we can push an entire column of rows in one go rather than an entry at a time. This should accelerate the writeRow() command. |

Better fix for this: Engine: modify colValueList (and dictStrList) so that the vector is [row][column] |
