I have around 7 LIVE sites running on a single server .the database we are using is oracle 8i .When the 7th site was not launched everything was working fine .But when we launched the 7th site .the 7th site is very slow.We traced it and found that the connection to oracle database is making it slow.We are using the same methods and drivers for all the sites to conect to the database.Sometimes it takes even less then a second to connect to the database but sometimes it take more then a minute
