# Execute 1000 insertions (i.e., 1000 groups , one transaction per group).

# Without the fix, it will take 1000 * binlog_group_commit_sync_delay which

|
# is 1000 seconds (> 15 mints). Hence test script will be timed out.
|
|
# But with fix, it should not take more than few seconds (that depends
|
|
# on Pb2 machine speed and also depends on various build options too.
