The Statistic for February was a little bit false, because in the Stats was listen the internal Traffic between the MX- and Reporting-Server from the same Datacenter.
In the Statistic from 03/2013 and after, the internal Traffic is not longer listen.
Currently, blocklist.de has the following Stats/User:
Daily Mails: ~200100 (lower limit) ~450000 (high limit)
Web-Traffic: ~200 GB
RBL-/API-Traffic: ~60 GB
Mail (In/Out)-Traffic: ~~2600 GB (But there was included the internall traffic) In 03/2013 we use now the local IPs, so the Traffic between the Reporting-Server was not longer included and the Traffic is going down
Traffic over IPv6 (Mail, Web..): ~3GB
To this data, there comes 2,5TB Traffic between the Web-/Mail-Server and the MySQL-Server. The MySQL-Server sends over ~5,2 GB each Hour out.
The Mysql-Server use now 50% from 32GB Ram. And the System-Load is in average on 1.20 .
The WebServer is using not full of 12GB Ram and the System-Load is under 0,7. The open Connections are ~4000
The complete Traffic from all Systems are round about 3,9TB in February 2013.
Only about ~1,9 TB without the internal Traffic between the MX- and Reporting-Servers.
