It was my really bad decision to purchase Zennoposter. No Doubt, Its a very awesome tool to have. Keeping in mind the popularity of the tool I wanted to give it a shot. I taught it would help me automate few of my easy tasks.. I got multiple template made and got it running.. It was slow as my VPS had 8GB only, the template guy told me it requires a lot of memory to run more threads. I got a dedicated VPS which had 32GIG RAM, 8Core Process and 1Gbps Dedi. But it got worst and more worst. When Zenno runs, it never uses more than ~10 GB's but renders the entire server useless to me. It uses 10 GB for 10 threads and it uses same amount memory for 300 Threads spread across mulitplate template. I just can't use it for anything else. I got in touch with their support. No one responds. I have agnosticon's server. He is an awesome guy. Helped me throughout. When I told him about it.. He suggested to install a Virtualbox on the server and dedicate 20GB and some cores to it. IT CRASHES ALL THE TIME. I got some replies on the their Forum but no one from the support ever responded. Its windows 2008 R2 Enterprise Edition - 64Bit, Its not a VPS but a dedicated server so the cpu bottleneck is not the issue. Its a HP DL360 with 2 x Quadcore Xeon processors, running 15K SAS Disks on Raid1 which I bet are the best and expensive drives out in the market. Did anyone face any problem like this? IF yes how did you cope with it?
