Most often, the internal optimizations described in InnoDB Data Storage and Compression ensure that the system runs well with compressed data. However, because the efficiency of compression depends on the nature of your data, you can make decisions that affect the performance of compressed tables: Which tables to compress.

Hence, it is very important for performance of InnoDB. The innodb _buffer_pool_size setting is the first one for performance tuning with InnoDB. This is the buffer pool size for data and indexes. One such parameter is innodb _flush_log_at_trx_commit. This parameter determines when the log buffer is written to the log file.

This also makes creation of FULLTEXT indexes faster. The InnoDB engine has a buffer pool used for caching data and indexes in memory.
