Hello, Galaxy developers: I'm a Galaxy user and to customize and deploy Galaxy server locally. I need to build a connection between Galaxy and database server now. MySQL and PostgreSQL are both configured to test the connection. ################################################ #for mysql server and db name is galaxy database_connection=mysql:///galaxy?unix_socket=/var/run/mysqld/mysqld.sock&user=<user_name>&passwd=<password_string> #for postgresql and db name is galaxy database_connection=postgresql:///galaxy?host=/var/run/postgresql&user=postgres&password=<password_string> ################################################ Now starting Galaxy server has no errors and I can create a user account on local Galaxy server successfully. But when uploading datasets into Galaxy(mostly less than 1 MB size) it remains "uploading" status(Dataset is uploading) and cannot complete datasets uploading job. I tested both PostgreSQL and MySQL and it really did not work. Shockingly using PostgreSQL the dataset uploading job can be accomplished very very slowly 3 or 4 times. wangdan
