JInspired Announces JDBInsight 2.0 @ JavaOne 2003
DUBLIN, IRELAND - 5 June, 2003 - JInspired (www.jinspired.com), a leader in J2EE™
transaction analysis, today announced JDBInsight 2.0, the next generation of J2EE
performance management products from JInspired. JDBInsight will be available for
preview at JavaOne 2003 in San Francisco.
JDBInsight is the first product to effectively integrate Java profiling information
with JDBC/SQL transaction analysis. Version 2.0 has numerous features derived
from its support of the Java VM Profiling Interface (JVMPI) such as Java call
stack analysis, CPU, blocking and waiting measurements at the transaction path
level.
The "Best Java Application Monitoring Tool" just got better. JDBInsight 2.0 sports
a new client interface that once again shows that JInspired is the leader in delivery
of rich and informative visualizations of J2EE transactions and performance execution.
The products innovative use of symbols and graphics is unrivalled within the Java
performance assurance industry.
With the new Java call stack classification engine developers, testers and J2EE
administrators can now understand the interaction of various technologies with
corporate databases. Classifications engines are available for Java enterprise
technologies such as EJB, JSP, Servlets, JTS, CORBA, JDBC, JCA, Web Services,
JDO and Struts. JInspired will also be announcing new engines over the coming
weeks for various web/persistence technologies such as JavaServer Faces, Tapestry,
WebWork, and Hibernate.
JDBInsight 2.0 is the first performance management product to have the ability
to detect and present resource transaction demarcations – allowing visual sub-transaction
identification.

JDBInsight 2.0 Terminal Services provides a quick and easy way to communicate
with multiple servers without having to use a graphical user interface. This facilitates
the streamlined connection, activation and deactivation of profiles on local or
remote servers with the ability to control multiple servers from a single terminal.
These Terminal Services also provide a powerful environment to create and schedule
snapshot information, in order to monitor servers at regular intervals, with the
ability to store and retrieve snapshots from any mounted drive, as well as providing
a rich set of commands to assist in analysis of this highly detailed data. Learn

About JDBInsight
JDBInsight is an innovative enterprise development product, aimed at simplifying
the performance tuning and testing of J2EE™ applications, which access data through
the Java Database Connectivity (JDBC™) API. JDBInsight analyses the access of
enterprise data by J2EE™ client-, web-, and bean containers. The analysis can
encompass transaction executions, from multiple J2EE™ containers. JDBInsight captures
timing and execution information for enterprise data accessed by Servlets, JavaServer
Pages, Session- and Entity Beans using JDBC™ or an Entity Bean using a container's
persistence engine. JDBInsight can also profile non-J2EE applications that access
enterprise data through the JDBC™ API.
About JInspired
JInspired located in Ireland, delivers JDBInsight, a comprehensive solution for
Application Performance Tuning and Testing that focuses directly on early identification
within the development and testing lifecycle. Jinspired offers sophisticated analytical
tools, that capture transactional behaviour and performance timing information,
across multiple containers in a single console, and presents this information
intuitively to the user "Visualizing the Invisible”.

Answer 1

CPU speed may play a role but after experimenting with Activity Monitor it looks like available memory is key. For example if I export a 100% crop of a 10 megapixel RAW file to JPG it sometimes takes over a minute. When this happens there is essentially zero free memory. Also, preview updates are usually running in the background. At other times there is ~100MB free memory and it performs better.
I do agree with a post elsewhere that on my machine, at least, the sliders have so much lag it is hard to get the effect you want. Constantly over and under shooting. Might be livable since some nice effects can be had if you work at it.
