In-memory files

In-memory files allow you to dynamically generate CFM files and execute them directly from memory. Memory-based

virtual file system speeds up the processing of transient data. In-memory files are not written to disk and are saved on RAM.

In ColdFusion, in-memory files help you simplify the execution of dynamic code. Though they function in the same

manner as disk files, they are faster. In-memory files are supported across all tags and functions that take file/directory

as input or output. They work in the same manner as files saved on the disk.

Improved Clustering

This release supports serialization of query, array, and datetime types in CFC.

Other performance enhancements

• Improved CFC performance

• Faster Java method invocation

Database enhancements

This release supports DataDirect driver version 4.0 SP 1. The feature helps to enhance database operations by

providing the following features:

• Support for MySQL (Enterprise and Commercial editions), Oracle11g, DB2v9.5, Informix 11, and SQL Server 2008

• Support for IPv6

• Option to set a default query timeout value

For more information, see the DataDirect Connect JDBC Support in the Configuring and Administering ColdFusion.

Note: By default, the datasource property MaxPooledStatements is set to 100 (and not 1000 as in the previous releases)

for the drivers DB2, Informix, MSSQLServer, Oracle, Sybase, and MySQL(DataDirect). Adobe recommends that you

maintain the default number of max pooled statements to avoid memory-related issues.
