I'm designing, programming and mantaining such kind of "n-tier" applications under Linux (since 1998) and MacOSX (since 2003). Most of those apps are designed to be served over the Internet to Web browsers or dedicated proprietary end-users clients.
Those apps are buid around Metacard or Revolution applications servers binded, one side, to Apache trough a ".PHP" based TCP/IP sockets listener/port translator and, second side, to a PostgreSQL 7.xx DBMS. You probably know, as me, that PostgreSQL (in between some others DBMS, such Firebird, SABDB or Sybase ASE, realy roocks. At this point, the only pending question is to know if the Revolution engine (or his father, Metacard) will roocks too, in acting as the applications servers engine. The answer is from my own experience fully positive : it's YES ! Some of my intensive "80% write-mode" apps are handling up to 200 connections/second 12/24 hours 6/7 days (Linux x86, Athlon 800, 1Go RAM, processor idle state always over 90%) and, i did never have a server stop or crash or any else problems from the production beginning : just one server restart when the provider has electricity hang-ups and, always without problems on the servers them self. I, just, don't know, for yet, what is the real charge limit of my MC/RR applications servers (400, 800, 1000, 1500, more ? connections/second)...
As, i'm, on the other hand working on a University académic project designed as a J2EE solution (Apache+JBoss+EJB2+PostgreSQL under Linux), i just can compare one of my MC-based apps, i cloned under the J2EE platform : the Java issue is OK too but seems to respond slower to the end-users requests.
At this time, i don't expect to switch my production's apps under the J2EE platform but, indeed, if i can get enought time, i will work in about porting the EJB2 design patterns architecture under the Revolution platform.
Ask, off-list, for more precisions, even for a test account on productions apps, if needed :-)
Hope this helps, -- Bien cordialement, Pierre Sahores

Hi,
has been testing Revolution for a couple of hours and looks a little bit
inmature. I don't want to be less polite, but my English...
I'm looking for a solution to develop cross platform applications, mainly for Linux and Windows. Our first choices was Delphi/Kylix and C++, but I found Revolution, cool name :-)
We have to develop multiuser programs like accounting and billing software with very intensive database use, the prefered databases are PostgreSql and Firebird.
Anybody could point me to samples of "big" applications developed with Revolution? Details? Reports? Links?
It is Revolution the right tool? other suggestion?
Regards,
Jose
