                 Key: CORE-5363
                 URL: http://tracker.firebirdsql.org/browse/CORE-5363
             Project: Firebird Core
          Issue Type: Improvement
         Environment: Windows 7 64 bit , i7 processor, 8GB Ram,  Firebird 3.0.1 
 (local)
            Reporter: Zeki Gürsoy


I tested table scan performance with 10 million rows on simple table.

--> create table mytable (id bigint, tutar decimal(15,2);

On Firebird               : select count(id) from mytable --> 7.52 second
On PostreSQL         : select count(id) from mytable --> 1.68 second
On MS SQL Server : select count(id) from mytable  --> 1.54 second

Firebird's table scan performance needs improve
