NUMBER OF RECORD PAIRS AND COMPUTING TIMES, BY PASS NUMBER - 2006 AND 2011

Table 2.1 shows the number of record pairs generated within each pass of the 2006 and 2011 projects, along with the associated computing times. While the number of comparisons contributes to the overall computing time required for each pass, the amount of concurrent server activity is another source of variance for the run times provided. The more robust linking infrastructure utilised for the 2011 Death registrations to Census linkage project resulted in much faster computing times than in the 2006 cycle for the large number of record pairs that were generated.
