Re: PERFORMANCE IMPROVEMENT: TESTERS NEEDED! (was: UNIX sysadmin observations)

You know what? I don't think we're going to disagree on much. This seems more like a matter of perception and at what angle you approach at the problem. As mentioned: " It is only to test to see if we've identified a performance problem and that we addressed it in a way that improves performance. " ...

Re: Some observations from a UNIX sysadmin

I'm going to provide a test plan. This is not intended to be a long-term solution. It is only to test to see if we've identified a performance problem and that we addressed it in a way that improves performance. SUMMARY: You'll run through a formal test plan that provides some structure for your own...

Re: Some observations from a UNIX sysadmin

MY GOD, I FIGURED OUT WHERE THE SLOWDOWN IS COMING FROM. I started to bring in some tools like ftrace and others to help examine where things were going wrong. After installing one tool and looking at page faults, I noticed that systemd-udevd was going through a regular cycle of activity. And the d...

Re: Some observations from a UNIX sysadmin

Thank you for all of those answers. I'll accept your offer of the AMT630A datasheet. That'll be a great help! What I'd like to see is if I can do a logical AND (in hardware) between the PWM output(s) of the AMT630A and the output of one of the unused GPIO pins. At a high level, that would allow me t...

Re: Some observations from a UNIX sysadmin

Performance tuning UNIX servers is something I do in my day job, so even though I'm just now getting up-to-speed with Linux, I thought I'd try my hand with some tuning of the RetrOrangePi distribution on my newly acquired RetroStone. At a high level, my findings (if accurate) seem to suggest that th...

Re: Some observations from a UNIX sysadmin

Good news? I worked on some of the performance problems with a game in MAME that I was quite familiar with: Tokimeki Memorial Taisen Puzzle-Dama. Sure, that's a pretty strange title forr an American to be familiar with, but I've got the game in my PCB closet as part of my Konami GX motherboard colle...

PERFORMANCE IMPROVEMENT: TESTERS NEEDED! (was: UNIX sysadmin observations)

Hi, everyone. This is a great project, isn't it? Me: I've been supporting Solaris servers for 20 years, but now I'm finally making the dive into Linux. The RetroStone is part of my at-home edutainment. I've only had it a full day, but I'm enjoying it and learning a ton about those Linux-specific qui...
