Hello, In the next weeks, I hope that I will start my first application with Seaside. The first version is ready. It's a set of REST web services. Now, I'm doing differents stress tests for evaluating the charge that my product can support. I'm using Pharo 1.2.1, Seaside, Seaside-REST, SqueakDBX, LDAPlayer and XML-Parser. For the connector, I use AJPPharoAdaptator for the link between my program and Apache. Have you ideas or good practices for optimising the performances of a Seaside application ? Of course, I can installing my application on differents servers and made load balancing but I think that the first thing that I must improve is the code himself. Working faster with a database and a LDAP are the first problems that I want resolve. Someone worked on the pools of connections ? What are the errors that I must avoid making ? It's a large subject but it could be benefit to share experience in the search of performance. Best regards Olivier ;-) www.auverlot.fr
