# Bug#21420180 BINLOG_GROUP_COMMIT_SYNC_DELAY SHOULD BE CONSIDERED ONLY WHEN

# 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.
