[firebird-support] Dynamic Memory Allocation

2015-11-05 Thread Köditz, Martin martin.koed...@it-syn.de [firebird-support]
Hi Todd, your description sounds like a problem with the concurrent connections. SuperServer works mostly sequential. So maybe there is a long taking query blocking the others. Maybe you should give a try to SuperClassic. For more information see http://www.firebirdsql.org/manual/qsg25-appx-ar

Hi Alan, It might not be an elegant solution, but I think you could also union the same query together 8 times and have the where clause "short circuit" if it is not supposed to execute. I would love to hear if anyone has any better ideas though, as this slowdown is something we have also seen.

Hi, I have a SP that has been running as is for many years on various servers and the performance is very acceptable. However, I have just replaced a dual Xeon test server with - wait for it! - a Raspberry PI 2 running a customised Linux OS. It runs perfectly well and I've benchmarked a number

Hi! I wonder: Was there any change in FB 2.5.4 which would slow down processing of WHERE field IN (subselect) a lot, compared to FB 2.5.3? I have been performing tests because a user of mine complained about slow speed of my database, and found out that my query in the form of: SELECT COUNT(*)
