[firebird-support] Concurreny transaction impact on writers

[zvjezdan77]

Hi. In highly concurrent environment, part of an app is using .NET 
RepeatableRead transaction to read data from few tables.
I noticed that during these reads, writers to these tables experience major 
slowdown.
So question is this:
Does (Concurrency,ReadWrite) (.NET RepeatableRead) has major impact writers?
