I could try a different AWS instance. Im running these tests on r4.8xlarge boxes, which are pretty beefy and "ebs optimized". I tried the same tests using IO1 disks at 20,000 IOPS but still had issues.
Dave with the i3 instances, were you using the local ssds? Or still using EBS? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
