Recently, I have found out that I can maximize mysql performance when if I have good hardware. Since I've been using InnoDB I added additional configuration into my.ini
Here is the newly added configurations:
innodb_data_file_path = ibdata1:10M:autoextend innodb_buffer_pool_size = 2G innodb_additional_mem_pool_size = 2M innodb_log_file_size = 256M innodb_log_buffer_size = 8M innodb_flush_log_at_trx_commit = 1 innodb_lock_wait_timeout = 120 Then I restart all of the services. But when I used my program, an error occurred "Unknown table engine 'InnoDB'".
What I have tried to solve this problem:

InnoDB is a general-purpose storage engine that balances high reliability and high performance. In MySQL 5.6, InnoDB is the default MySQL storage engine. Unless you have configured a different default storage engine, issuing a CREATE TABLE statement without an ENGINE clause creates an InnoDB table.
Storage engines are MySQL components that handle the SQL operations for different table types. InnoDB is the default and most general-purpose storage engine, and Oracle recommends using it for tables except for specialized use cases. (The CREATE TABLE statement in MySQL 8.0 creates InnoDB tables by default.)
Other solutions did not fix my problem. InnoDB engine was disabled after adjusting config.
Removing borked ib_* log files in mysql data dir fixed my issue, and allowed me to use 2G buffer pool for InnoDB: http://www.turnkeylinux.org/forum/support/20090111/drupal-6-problem-enable-innodb#comment-131
