G5 vs. x86 and Mac OS X vs. Linux
demonbug writes "Anandtech has an article up comparing performance of dual G5s to AMD Opteron and Intel Xeon workstations. The article also takes a look at performance under Mac OS X versus Linux. It provides an interesting look at some of the strengths and weaknesses of the different CPUs." From the article: "This article is written solely from the frustration that I could not get a clear picture on what the G5 and Mac OS X are capable of. So, be warned; this is not an all-round review. It is definitely the worst buyer's guide that you can imagine. This article cares about speed, performance, and nothing else! No comments on how well designed the internals are, no elaborate discussions about user friendliness, out-of-the-box experience and other subjective subjects. But we think that you should have a decent insight to where the G5/Mac OS X combination positions itself when compared to the Intel & AMD world at the end of this article."
I will point out that this is hardly relevant for a desktop OS, and that I am more than happy with my dual G5/1.8GHz. Getting things done faster and neater due to elegant interaction design is much more important to me than being able to spawn threads quickly ;)
Except that they used Apache 1.3 and MySQL, two of the worst possible choices. If they'd gone for Apache 2.x (which actually uses threading, instead of processes) and PostgreSQL, things would've looked much nicer.
1. MySQL -does- have a thread pool.
2. The threading engine on OS X really does suck. This is not new information. Apple says as much if you ask them.
This will all get fixed in due course anyways - Linux is more than a decade older than MacOS X is, and Apple is already doing very well.
