This is seriously getting bad.
First contact with DH support was on May 28 regarding the page loading/processing speed. I've come to the conclusion that bandwidth is not the problem by downloading images and tar files at about 8Mbps (my cable connection limit). Server load on my webserver (hyperion) is also not the issue (load average: 1.70, 1.32, 1.13).
Where I do see an issue is connecting to the mysql server from the webserver. I'm not sure of any other way to check the connection, but by doing trace routes, I'm seeing intermittent time outs on the last hop to the mysql server. DH has stated this may be related to DNS, which I wouldn't doubt.
What's up, though? Every one of my communications with them is "is it working now?". Seriously, why can't they at least attempt to help me, after I've gone over and beyond trying to help troubleshoot this.
It is now June 8 and I'm still awating even an acknowledgement that they are trying to help me. 24 hours response time is bullshit.
