PHP PDO Mysql Insert Performance

Question

I normally don\'t use a lot of SQL stuff in PHP but recently have been forced into it by a friend as to help him debug something.

I am using PDO with PHP to insert some

Answer 1

Turns out that a setting inside the SQL server is what was causing it. As far as I can tell the transaction commit was set to flush to disk on every write:

innodb_flush_log_at_trx_commit=0

This is the default ACID compliant settings of a new install.

I changed my setting to this

innodb_flush_log_at_trx_commit=2

This allows ONLY power outage or OS crash to erase the transaction buffer/log and not a mysqld crash.

For some people who need the "D" of ACID to be 100% true then you should leave this setting alone.
