Discussion the OSX for Realtime Performance on ArsTechnicaForums
There is a discussion going on about my document in the Arstechnica.com forum.
I was quite surprised to see my dokument discussed on arstechnica.com, my absolute favorite tech site on the net. So I was quite sad that all that is there is bashing and no constructive criticism. I do need feedback for this document as I want to advance this further and the more technical advanced people give me more scoop on what is going on inside this system and where we could get some more juice out of it.
as for some of the objections raised in the thread until now:
the font: This is not a GOTHIK font it is a Fraktur Font. and firstly I am an artist if I want to put out a dokument with a fraktur its my thing you can just copy paste the text and give it any font you like. Secondly I explained why I used this and I have emails sitting here telling me that this works quite well. Up to 50 years ago ALL written word was in this style so it must be readable donīt ya think? maybe your reading has degenerated into something that is not worth called reading? maybe you do not care for detail anymore?
the chmod 7777: There was no other way to make this script run on a friends computer as he run into permission problems, this was a problem with filevault and totally unrelated with the script. Yes it needs to be only 755 sorry about this...
apache is not using resources: that might be, but I tried to slim it down as much as I could, WITH EVERYTHING removed that MIGHT be causing trouble making the bootprocess slower etc. Apache I do not need in a realtime environment.
there might be problem with other stuff I removed:If you would have read the document I said explicitly: This system is only there for running this single Application. If you plan to do other stuff you will run into problems sooner or later. I know that deleting the cron jobs is not a smart thing to do on a heavy used system. I personally have seen the cron jobs kick in the middle of the night when I was standing in fron of 8000 people and this slowed down my computer. there was no way I could have stopped them manually. This document is for the lesser computer literate and I have a hard time to explain how to move the cron jobs to a time when there is no chance you have a performance. Besides I can never tell when I have a performance, sometimes I do gig during the day for a presentation or during the week during a festival or on sunday to monday night. So for me deleting the cron jobs was a good way to get around this problem. I try to eliminate ALL disk access from the system and cron jobs surely have diskactivity.
I donīt believe the 20% performance increase: Have you tried it? I did not believe it myself. I do have two system running side by side and I can clearly see this difference... Maybe I really need to do benchmarking thing. I hate benchmarks they are so far out of reach in a working environment. I have top and top tells me that I have up to 22% processing time free when running VDMXX under certain circumstances and under the same circumstances I have no processor free (0%) when running it under the non optimized system.
So if you have constructive criticism I like to hear it. Bashing is not in place except if you have something better to offer which then I would love to hear.
