Hi Team, I would like to know few performance related information. We have capacity planning meeting for setting up a new cluster with AT. So your input will be a great value add in our capacity planning.
Questions: 1) YTS(Yahoo Traffic Server) has some performance optimization which utilizes the RAID-10 level for effective cache lookup. Does this ATS also holds the similar type of feature which will gel well with RAID 10 level. If not we will go ahead with RAID 0 to save more disk space for larger cache. Currently we have 300GB cache on each ATS nodes. 2) How does ATS scales with respect to CPU , Memory, Disk? We have our current production running with YTS and 16GB ram. Will ATS scale its performance If I am getting 24GB ram ? How ATS will scale with respect to hardware. Can you please give some insight about it. 3) What is the QPS of current ATS? PS: Please treat this email as high priority, all your inputs will be valuable to me. Regards, Karthick
