Subject ATS - Performance Related Questions - High
Date Fri, 08 Nov 2013 09:31:54 GMT
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.

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.
