Over the holidays, I completely re-did my UIview APRS webserver setup.?? It's
now ready to be hammered by a bunch of users to see how the new setup handles
the load.
I have replaced the 2012-vintage Acer AO756? "netbook" mini-laptop that has
been doing APRS Webserver duty for over 6 years,
.???? [Reviewed here? <> ]
with a later generation E3-111 netbook. ?? I maxed-out the new one with 8GB ram
and replaced the 500 GB mechanical HDD with a Samsung 1TB SSD.? The thing now
boots in about 15 seconds instead of two minutes.?? (You don't get the full
benefit of the blazing speed of the SSD since the motherboard and drive
controller interface of the Celeron-based netbook are relatively low
performance.? But is still far faster than the rotating hard disk.)
The SSD has another benefit:? Since this machine runs server duty 24/7/365, I
like to get the power consumption as low as possibile.? Running the mechanical
hard disk, the machine consumed 10 watts. With the SSD, the power drain dropped
to 8 watts.
A Rosewill 10-port powered USB hub is now connecting THREE of the Behringer
external soundcards,
.???? [Reviewed here:? <> ]
two USB<-->serial dongles (for the Echolink interface and for CAT of the FT-100
used for the IARU beacon monitor), and the USB-interfaced X10 controller. It's
now running THREE VMware virtual machines + 4 apps on the host. Between the
Win7-64 host and the 3 Win2003 VMs, it is now running EIGHT copies of UIview
simultaneously with only about a 35% CPU load.
The host runs the 30M HF UIwebserver, APRS Messenger, the BeaconSee IARU beacon
monitor, and Echolink + the three VMs. VM#1 runs 4 copies of UIview? on 2
meters - they show off-air activity for all of lower Michigan, the greater
Lansing area, the metro Detroit area, and the Michigan State Univ? campus.?
VM#2 runs the ISS SatGate.? VM#3 runs the "Special Events Server" which is
currently setup for the Livonia (greater Detroit area) hamfest coming on 17
Feb.? (The special events server uses two instances of UIview to produce a
regional area view and a close-up aerial photo view of the venue.)
It's all at <> as before.
On this gateway page, there is a link to yet another UI-Webserver for 60
meters.? On 5 Feb, I will be going on a road trip to New Orleans and will be
testing 60-meters APRS again.
