    <p>For developing in PHP I use the PHPStorm IDE which has an embedded FTP client. Whenever I upload a file to the FTP Server, I get 2-5 second delays, which causes the file upload to take ~10-15 seconds. It has to be related to SSL, either the netotiation or the verification of the server certificate by the FTP client. Whenever I switch to FTP, the upload is lightning fast. I should also add that when I connect with a different client (FileZilla) uploading and downloading works perfectly fine. I have ruled out the UseIPv6 and IdentLookups options, turning them off has no effect. I connect in PASSIVE mode so that's not causing any problems either.</p> <p>I'm out of ideas and could really use some help! Thanks.</p> <p>The FTP server is proftpd 1.3.4a on a Debian Wheezy machine.</p> <p>proftpd.conf:</p> <pre><code>Include /etc/proftpd/modules.conf UseIPv6 on IdentLookups on ServerName "domain.tld"

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
