Re: [firebird-support] Re: Is windows better than Linux for Firebird 2.5 64 bit?
Not sure if Firebird performs in s standard way related to filesystems, but I've found a good report about databases and filesystems on Linux: http://highlandsun.com/hyc/mdb/microbench/MDB-fs.ods Maybe it can help.

W O wrote: And what about Ubuntu Server? What do you think, is it good for Firebird or not? Since the core stuff is the same on all distros 'which is better' is somewhat academic. I'm running a number of machines 'command line only' over ssh at remote sites so the bulk of the differences with desktop set-up do not apply. Some of the machines I've never seen except over the wire and I'd rather than Linux in that case. It *IS* all just a matter of what else you need to run. In my case the latest Apache and PHP are not currently supported on a stock SUSE set-up, so I'm switching newer machines to Fedora 17 which does. Firebird has a little better support on both so if you don't need the rest it's not so critical. Ubuntu is another base that is still on the last major release of Apache and PHP. No doubt someone will say 'Manually install', but this introduces a lot of other problems when the distro has 'it's own way of working' even Firebird files end up in different places and can pick up old versions if they are not removed properly. The comment that 'there are more pitfalls' is perfectly correct, but at least managing them is somewhat easier than tracking a dodgy update on Windows ;) -- Lester Caine - G8HFL - Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk

Hello, trskopo! Wednesday, November 7, 2012, 9:29:05 AM, you wrote: t 1) What drivers in that should exist for better performance? My t guest is CPU and Harddisk, is this correct? yes. But even you buy brand hardware, drivers can be bad in performance. t 2) Assuming that Linux and windows has correct drivers, which one is better? It can be understood only by test. Linux is much specific, as I said. For example, on some hardware Linux (CentOS) was 30% slower than Windows (for FB Classic with ~400 active connections). 2. You can choose linux distro by your preferrence. If you don't know any Linux well, then, you will have troubles. t I am thinking using CentOS or Suse, what distro do you use for yours? I do not use Linux :-) but our clients - use latest CentOS and Suse. -- Dmitry Kuzmenko, www.ib-aid.com

Hi Lester, Thanks for your reply. So the question should perhaps be ... what are you using with Firebird? I am using firebird in client-server environment for accounting application and mostly only in a LAN. About file system, (if I didn't mistaken) someone here mentions not to use specific file system, because it will decrease firebird's performance. Regards, Sugiarto

Hi Dmitry Kuzmenko, Thanks for your reply. 1. Windows can be better or slower than Linux on same hardware, depends on hardware and existing drivers for hardware for Linux and Windows. Difference can be up to 30% of performance. 1) What drivers in that should exist for better performance? My guest is CPU and Harddisk, is this correct? 2) Assuming that Linux and windows has correct drivers, which one is better? 2. You can choose linux distro by your preferrence. If you don't know any Linux well, then, you will have troubles. I am thinking using CentOS or Suse, what distro do you use for yours? Regards, Sugiarto
