i've been having some issues with EC2 too.  Are you actually paging from
memory to disk or just using the WAL for durable memory?  you can use a
different walMode to make it "better".

I was playing with 


Which means it flushes the wall every 10 seconds in the background

Hi All - I am using Ignite Persistence ( 2.3) for storing events that we
receive from different sources. Currently the write and read throughput is
2k to 4k per second on a t2.xlarge and c4.2xlarge machines on a 3 node
cluster. The disks attached are provisioned SSDs with 1 IOPS.  These
numbers are not very encouraging and I am wondering if there is any way to
improve or I am missing something fundamental..

The event size that i have is around 1kb.

The datastorageconfiguration config is as follows :





















Not sure the details i have provided are good enough to give a concrete
suggestion, so let me know if you need more info.
