The size in bytes of the buffer that
is 1MB. Sensible values range from 1MB to 8MB. A large log buffer enables large transactions to
run without a need to write the log to disk before the transactions commit. Thus, if you have big
transactions, making the log buffer larger saves disk I/O.

Variable Name

Dynamic Variable
The size in bytes of each log file in a log group. The combined size of log files must be less than
4GB. The default value is 5MB. Sensible values range from 1MB to 1/N-th of the size of the buffer
pool, where is the number of log files in the group. The larger the value, the less checkpoint flush

activity is needed in the buffer pool, saving disk I/O. But larger log files also mean that recovery is
slower in case of a crash.
