Yes, I have no antivirus on my local computer and it has 1GB memory and 3+ GHz Intel IV processor, UW 320 mb/s SCSI HDD, etc... Other my own programs with VFP+MS SQL Server 2005 are "flying" on this computer :)

DBF version of this Opera II program works quite fast, but MS SQL Server - very slow...
