Hi Hector, I discovered something else quite interesting: I realized both IB and FB dbs have pagebuffers set to 100.000. I changed FB to 0 and now it works like I expected!!..Same query now completes on FB on 50 sec. It seems this is the problem although I don't understand why. 100 000 is

Re: [firebird-support] About firebird performance

Not exactly the same machine, but almost...same server config, same linux distro. In order to make tests with FB try to be comparable I tried to have exact the same machines. I'll do what you suggest and post results. There must be something stupid but I cannot see it as it's not possible
