Latency Comparison between cloud hosting Vs Dedicated hosting
Hi, We are comparing search request latency between Amazon Vs Dedicated hosting [Rackspace] .For comparison we used solr version 3.6.1 and Amazon small instance.The index size was less than 1GB. We see that the latency is about 75 -100 % from Amazon. Any body who has migrated form Dedicated hosting to Cloud has any pointers for improving latecny? Would a bigger instance improve latency? Regards Sujatha

Re: Latency Comparison between cloud hosting Vs Dedicated hosting
Hi Sujatha, You should really do the same stuff to improve latency in the cloud as what you would do on a dedicated server. Amazon-specific stuff: Bigger EC2 instances have better IO. EBS performance varies. Some people mount N of them and stripe across them. Some people try N EBS volumes to find the best performing one(s) and discard the rest. Some people pay for provisioned IOPS.
