Hi,

first potential thing – transaction management.
Probably you have transaction long running and it stop garbage collector to 
process old record versions

Look into MON$TRANSACTIONS

Subject: [firebird-support] Potential Causes for Query to Slow Down

  
I have a Delphi Application that uses FireDac to communicate with Firebird 2.5. 
 I have a query that periodically slows down fro about 5 secs to many minutes.  
If I backup and restore the database, I get my original performance back.

What kind of things could cause this behavior.

Thanks in advance.
