Whenever I put load on the node, the CPU gets spiked and so does my disk writes. What I 'm failing to understand is when I stop the load, the CPU usage goes back to normal (1-2%) my diskusage (write) remains very high, even after 30-40 mins after the load was stopped. So wanted to understand what is the writes being used for. <br /> <br /> My size in mempool is one which should mean the blocks are confirmed. <br /> <br /> &nbsp;<br /> <br /> 27598 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;66572K &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;147.5M &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0K &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;100% &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;multichaind<br /> <br /> This is atop command. Similar WriteOp/sec I can see from AWS cloudwatch on my volume. <br /> <br /> &nbsp;<br /> <br /> Thanks,<br /> <br /> Ashish https://www.multichain.com/qa/7573/why-multichain-is-using-so-much-of-write-iops Fri, 17 Nov 2017 11:11:38 +0000
