Message-ID: <60B61FF6-E02E-40D1-9909-B4A047C2B6DA@gmail.com> (raw)
I'm so glad to see this mailing list. I started to play with the RPM test, and now I know where I can send feedback. I recently installed Monterey b2 on a Parallels Desktop VM on macOS 10.15.7 on a 2019 MBP. I have several observations/requests:
1. I felt the urge to include identifying information along with the networkQuality program's output. I wrote a script that includes a date/time stamp plus a text parameter to identify the test. (Prior "art" - my coffee-shop-bloat-test.sh at https://github.com/richb-hanover/coffee-shop-bloat-test.) Here's the checkNetworkQuality.sh script:
========
#/bin/bash
# checkNetworkQuality.sh - display RPMs for this network
# Parameter is a user-entered description for the test condition/location/etc.
echo `date`: $1
/usr/bin/networkQuality -v
========
2. Feature Requests: From this experience, I would like to see /usr/bin/networkQuality enhanced to (always?) display the date/time of the run, and to include an optional parameter for a test name/information. These parameters should also be included as new properties of the "-c" output. In addition, it might be good to include the build number in the output
3. I ran the test several times on my connection through an IQrouter v2, with 25/25 mbps fiber optic service. I notice significant variance in the RPM numbers, and do not believe there was any other significant traffic at the time. Is this variance expected?
4. I do not know what happened to the network at 12:06:56 EDT (see below). It obviously recovered 15 seconds later...
Thanks for listening!
