Subject Re: [firebird-support] FB 3 issues with String from FB 2.54
Hi Kjell

We had a FB 2.54 DB with a few varchars defined as charset ASCII, the intention was to stop users from entering unreadable characters, so the charset was there to attempt to filter garbage, at least that was the idea), anyways we converted all domains from charset ASCII to NONE, and then backup and restore onto FB 3.0, and it all worked fine. So I guess we were lucky, and the migration process was not too painfull. On the flip side, the performance we are getting on 3.0 is worst than on 2.54.... it seems the SMP is not active as only one processor is doing all the job, and CPU affinity is set to zero, so we are not sure what's going on.
