I also need a new Host. I have a few Wordpress Autoblogs. Some have up to 50000 Postings.
I have an Account with Hostgator. But my Sites are very slow there. Purging old Posting takes ages.
So I rented a VS from Host Europe (Germany). I was happy with them at first, but I'm having huge Problems right now.
I have 10 Sites on that VS and the biggest has 20000 Posts. For the last few days everything was very slow. I use w3 Total Cache to lower Server load, but the Main Page still loads very slow. Then I checked the CPU Usage and noticed that its constantly above 90%. I submitted a ticket and they replied that my VS is taking to many resources and they will take my Sites down if I don't change it.
So yesterday Morning I installed mpm Worker Package for Apache to try to lower the CPU Usage. Unfortunately this wasn't a good idea, as it messed up everything. I can not access any of my Sites since yesterday. Even uninstalling mpm Worker didn't work.
So I sent a ticket to support, but they haven't answered until now.
So I just moved 2 of my best performing Sites back to Hostgator, as I don't want to get delisted from Google. But those Site are slow as hell now.
Damn I'm frustrated. Another Proble is that I don't have Internet at home right now, because switching my ISPs didn't work smoothly. My old ISP switched me off on Nov. 15 and I will be offline until Dec. 06 when I get Service from my new ISP.
So right now I'm sitting in my Mothers Apartment, trying to fix what I can.
...so to the Point. I need a Webhost with enough CPU resources. 20000 Postings is not THAT much. All my Hosts were good a the beginning but became worse after some time has passed.
