This variable ( ON / OFF ) enables profiling of all queries (in all connections). profiling_use_getrusage. This variable ( ON / OFF ) enables usage of getrusage function in profiling. Be careful, enabling profiling_server may cause performance degradation, especially with profiling_use_getrusage. |

| innodb_check_fragmentation.patch | innodb_check_fragmentation | 1.0 | Percona | GPL | This patch adds several session-scoped status variables to the MySQL server. You can use the variables to compute the fragmentation of the InnoDB data scanned in the last query executed by your connection. You can compute the fragmentation for both table scans and index scans. |
| innodb_io_pattern.patch | Information schema table of InnoDB IO counts for each datafile pages | 1.0 | Percona info@percona.com | GPL | INFORMATION_SCHEMA.INNODB_IO_PATTERN |
| innodb_fsync_source.patch | Information of fsync callers in InnoDB | 1.0 | GPL | ||

| innodb_dict_size_limit.patch | innodb_dict_size_limit | 1.0 | Google, Percona | GPL | This patch limits the size of InnoDB's data dictionary. It fixes the following problem in standard InnoDB: the data dictionary is unlimited in size, and can grow extremely large. The size depends on the number of InnoDB tables in the server. Once opened, a table is never removed from the data dictionary in standard InnoDB, so the visible symptom is steadily increasing memory usage. See the examples to see how to compute the memory usage that may be caused by this problem. |
| innodb_extra_rseg.patch | innodb_extra_rsegments | 1.0 | Percona info@percona.com | GPL | innodb_extra_rsegments. The number of extra user rollback segments created when new db is created. New information_schema table innodb_rseg shows information about all rollback segments |

| File | Name | Version | Author | License | Comment |
|---|---|---|---|---|---|
| innodb_split_buf_pool_mutex.patch | innodb_split_buffer_pool_mutex | 1.0 | Yasufumi Kinoshita | BSD | This patch splits the single global InnoDB buffer pool mutex into several mutexes for different purposes. This reduces mutex contention. It may help if you suffer performance loss when the working set does not fit in memory. You can detect buffer pool mutex contention by examining the output of SHOW INNODB STATUS and looking at the first section, SEMAPHORES. |
| innodb_rw_lock.patch | Fix of InnoDB rw_locks | 1.0 | Yasufumi Kinoshita | BSD |
