Re: [firebird-support] About firebird performance

Thanks Alexey!! As you have read, setting pagebuffers to 0 on the database solved the problem and now it works as I expected. 2015-09-05 19:06 GMT+02:00 Alexey Kovyazin a...@ib-aid.com [firebird-support] : > > > Hi Hector, > > > I discovered something else

[firebird-support] About firebird performance

I'm doing some basic tests with Firebird and I'm facing something I cannot understand (I'm a newbie to Firebird which has worked with IB7.5 for years, so I apologize if I ask something obvious): - I have a linux server with firebird 2.5.4 Superserver: multi-core (4), 3GB RAM - I placed a "huge"

Re: [firebird-support] About firebird performance

He again Alexey, As I suspected, my problem is not caused by GC: gstat over the table reported this: TABLE1 (503) Primary pointer page: 9374, Index root page: 9375 Average record length: 317.63, total records: 3261775 Average version length: 0.00, total versions: 0, max versions: 0

[firebird-support] Re: About firebird performance

Re: [firebird-support] About firebird performance

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. Nevertheless, I'll try on a

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

Re: [firebird-support] About firebird performance

Thanks Carlos...environments are exactly the samethat's why semmed strange to me. It might be caused by the way FB and IB access disk that it's different in some way and makes my VMs get saturated. I'll try on a physical server and let you know. 2015-09-05 15:52 GMT+02:00 'Carlos H. Cantu'
