Node.js performance

I have now performed performance test and here are some figures:

Windows machine:
WIN 8 Prof - Intel I3 2 cores 3.4 Ghz, 16GB ram

IBM i V7R3 (IBM PDP) - POWER8 2 cores, 3,32 Ghz, 4GB ram

zDemo01.js (reads IFS JSON file based on QIWS/QCUSTCDT and writes
JSON output through zJsonStore

WIN: 0.7ms
IBM: 0.5ms

zDemo05.pgm, RPGLE - runs native SQL and reforms result using powerEXT/YAJL
zDemo06.js, javascript - runs db2a SQL and output JSON result via
JSON.stringify
The program basically does the same.

IBM - zDemo05.pgm: 0.7ms
IBM - zDemo06.js: 17ms

All programs are run in a sequense of call's and cold starts are left out
of the
average times.

Another little thing about running in blocked mode vs. unblocked:

When I start my HTTP daemon it writes a log that previuous was done with
console.log but now writes to a log.txt file in unblocked mode.

$Util.log('\r\n')
$Util.log('powerEXT node.js HTTP Daemon Starting')
$Util.log(' root: ' + modRoot);
$Util.log(' scope: ' + scope);
$Util.log(' port: ' + port);
$Util.log(' reloadMode: ' + funcObj.reloadMode);
$Util.log(' versions:\r\n' + JSON.stringify(process.versions, null, "\t"));

The result of console.log (blocked mode) and log.txt (unblocked mode)
is that in the console the messages comes in the sequense they are
made but in log.txt is written in a random order.

This may also be the case if you write to Data Queues where queue-entries
even from the same node.js script may be received by the backend server
program in the wrong order.
