Olivier should not be shy :)

I think that lot of people can be interested by FTL (faster than light)

Subject: Faster That light
Hi Mariano,

I have worked the last days on a generic connection pool for Pharo. The objective is to improve performances for an application that uses a network data source (databases, LDAP, etc.).

My work is now stable and the gain of performances is good. For exemple, I have a benchmark that uses a SqueakDBX/PostgreSQL database and a LDAP directory. Without the pool, the test take 6,61s, with the pool, only 0,367s :-)

I have made many stress tests for testing the fiability. This morning, the connection pools has processed 270000 requests without problems.

I think that my project can interest you. I don't know if the code is ready for production.

The projet is on squeaksource and I have added your account (and Stef also) as Guest.

Hi Olivier. First, let me say that we really appreciate your project and we are happy with it :)

Now, to avoid reinventing the wheel, I want to point you some stuff.

1) There is a GlorpDBX connection pool available. This is the package GlorpDBX-ConnectionPool.
Documentation: http://www.squeakdbx.org/documentation/SqueakDBX%20connection%20pool%20for%20Glorp

2) There is a general purpose pool (for any kind of object) that also work in Glorp or DBXTalk.

There is a package ObjectPool-GlorpDBX :)
I cc'ed Panu, the developer.

So...maybe you can join forces with him?

sure it does!!!

It doesn't matter. It is good to know about it.

Thanks. I will take a look. For the pools, the expert is Diogenes and Panu :)
