What is Doctrine?

Doctrine is a popular ORM for PHP which works with RDBMS via PHP objects. This is built inspired by Hibernate from JAVA. This acts as an abstraction layer between PHP and RDBMS.

Inserting 20 records with Doctrine

Compare it to some raw PHP code

Insert performance

Doctrine 2 = 0.0094 seconds

mysql_query = 0.0165 seconds

Doctrine 2 is faster than raw PHP???

Why? The answer is transactions! Doctrine 2 manages our transactions for us and efficiently executes all inserts in a single, short transaction. The raw PHP code executes 1 transaction for each insert.

Here is the same raw PHP code with proper transaction usage

Insert performance

* Not trying to say Doctrine 2 is faster than raw PHP code

* Demonstrating that simple developer oversights and mis-use can cause the greatest performance problems

* This time around it only takes 0.0028 seconds compared to the previous 0.0165 seconds. Pretty cool, huh!
