WD my Cloud it enables smb/cifs protocol so a network share can be mapped as drive In Firebird 2.5.x is possible with RemoteFileOpenAbility 1 in the firebird.conf (With a few big warnings if you read the conf file) you need to take care only the Firebird server to have access to that NAS share (exclusive access) I recommend an usb3.0/thunderbolt ssd drive for io speed If you follow this benchmark As you can see, performance with random IO operations shows ~8x better results for SSD drive. We knew from our experience with customers databases that SSD is 30-50% faster with real-word applications, but 8x increase is very high. http://ib-aid.com/en/articles/firebird-performance-degradation-tests-myths-and-truth/ http://ib-aid.com/en/articles/firebird-performance-degradation-tests-myths-and-truth/

[firebird-support] Re: Is it possible to store firebird DB file on a NAS?
Hi,Thanks for you reply. If I understand correctly, WD Cloud come with password to access private folder. So, I am planing to install FB server where NAS attached and set private folder in NAS, then map this folder as a network drive. Other users, don't have direct access to this private folder. Accessing FB database is just the same with format comp name:network drive on NAS With this setting, is this necessary to set RemoteFileOpenAbility = 1? WD Cloud come with pre-installed harddisk, so I can't replace its disk. I still have a doubt with this cloud, it got good reviewer by some webs, but got bad rating by users experiences. Regards, Anto

Re: [firebird-support] Forced write, page size and buffer size
Rich, I got the point: with forced writes off you can't be sure of when the data is sent to disk. But, in that case, what is the point of turning it off ? If you must wait for the server shut down to be 100% sure that the data is written to disk, isn't the risk too high to have forced write off ? I suspect that data is written to disk far before than the server shut down or a connection close, otherwise FB designers shoudn't leave forced write as an option, it should always be activated.

Re: [firebird-support] Forced write, page size and buffer size
Carlos, I agree with you. The performance degradation was very high on an ext4 file system ( which has barrier enabled by default ). On the other hand, I found no noticiable performance degradation on an ext3 file system ( which has barrier disabled by default ). Having barrier disabled on a server with an ext3 file system, does FW=ON improve reliability or is it useless ? Aldo Caruso El 18/08/14 a las 16:27, 'Carlos H. Cantu' lis...@warmboot.com.br [firebird-support] escibió: Usually, if you turn FW = ON on Linux, and your filesystem has barrier enabled, it will affect performance of batch updates really badly.

ACacacfs After that I noticed that some massive updates ( 100K records ) took ACacacfs nearly 5 minutes, whereas with async writes it used to take 10 seconds. ACacacfs One solution is, of course, disabling sync writes when doing massive ACacacfs updates. Unfortunately not always massive updates are under database ACacacfs admin control ( some end users actions can lead to massive updates, ACacacfs indirectly, by means of triggers ). ACacacfs Another aproach I tested was augmenting page size from its default ACacacfs value ( 4 KB ) to its maximum allowed value ( 16 KB ). The speed was ACacacfs notably enhaced ( 1 minute for the update + 10 seconds for the commit, ACacacfs but sometimes 2 seconds for the update and 40 seconds for the commit). ACacacfs It should be pointed out that 4 KB was fine, taking into account ACacacfs record size ( max. 300 bytes ) and index max depth ( always 3 ). ACacacfs Going one step further, I augmented cached pages from its default ( ACacacfs 2048 ) to 8192. Some small performance improvement was observed, but not ACacacfs very significative. It shoud be noted also that, with a 16 KB page size, ACacacfs the database has 5700 pages on disk, so there are enough cache pages to ACacacfs hold the entire database.

Re: [firebird-support] Forced write, page size and buffer size
RE: [firebird-support] Forced write, page size and buffer size
Afair, in previous talks, Ann suggested that if you have to choose one or another, choose FW ON. The best thing would be if someone could simulate some crashes (like power failure) in both configurations and report back about existence of corruption. Unfortunately, it is not always possible for a simulation to catch all possible modalities. The hard truth is that the only _absolute guarantee_ to prevent database corruption is FW = ON. Sean
