问题 I'm running this command grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage "%"}' Yet it only outputs something like 0.99xxxx% If I do an apt-get upgrade or any process, I would imagine it would go above 1%. Even running stress -c 1 doesn't make it change any. Is there a way to log CPU usage accurately? Server has 1 vCPU. Need to have this log every 5 seconds. while sleep 5; do "code" >> logfile; done 回答1: Why does cpu load not change more than a few hundredths?

问题 We are developing a Javascript control which should be constantly connected to a server for receiving animation updates. We are planning to host this stuff on an Amazon cloud. The scenario is like this: server connects to activemq queue waiting for updates, for each update it broadcasts it to all connected clients. Is it even possible to handle such load with node.js + socket.io? Will a single node.js server be able to handle such load? How to organize fast transport between different nodes
