# This script displays the field of rectangles used by --testset rtree
|
||
|
|
# of speedtest1. Run this script as follows:
|
||
|
|
#
|
||
|
|
# rm test.db
|
||
|
|
# ./speedtest1 --testset rtree --size 25 test.db
|
||
|
|
# sqlite3 --separator ' ' test.db 'SELECT * FROM rt1' >data.txt
|
||
|
|
# wish show_speedtest1_rtree.tcl
|
||
|
|
#
|
||
|
|
# The filename "data.txt" is hard coded into this script and so that name
|
||
|
|
# must be used on lines 3 and 4 above. Elsewhere, different filenames can
|
||
|
|
# be used. The --size N parameter can be adjusted as desired.
