In a proenv session:
Linux:
#!/bin/sh
#
# Similar to:
# dd if=sports.b1 of=foo oflag=dsync
#
# minimum acceptable result is 10MB/sec -- or 9 seconds
# 4 or 5 seconds is "good"
# 3 or less is excellent (probably SSD)
prodb sports sports
proutil sports -C truncate bi -bi 16384
ls -ltr sports.b1
time proutil sports -C bigrow 2 # -zextendSyncIO
ls -ltr sports.b1
# time dd if=sports.b1 of=sports.b1.dd oflag=dsync
In Windows:
prodb sports sports
proutil sports -C truncate bi -bi 16384
proutil sports -C bigrow 2
Then check the timings of the bigrow in the db log file.
