Hi, I'm currently testing several databases for an application written in Delphi 7. I use zeos lib to access PostreSQL8-RC1 on MS-Windows 2000 SP4. PostrgreSQL is extremly slow, with a lot of disk access on INSERT request. Have-you seen this problem ? May be some parameters should be adjusted. What should I check ?
