Let’s start at the end. I’m sorry if I’m spoiling this for anyone, but it has been hours at this point and Twitter has p

I had previously speculated about how Apple might handle their Mac-bound silicon, perhaps making an ‘A14T’ for the Macs.¹ Call it what you want, it sure sounds like it’s based on the A14 5nm architecture of the latest iPhones and iPads. The more interesting question I pondered is if that first iteration would be bound for MacBook Pros and iMacs,² while another new chip would be for the desktop-class ‘Pro’ Mac models.

We are comparing different execution models in this test — the Go application was compiled into a natively executable binary whereas the Java application was compiled into byte code that was then run on a virtual machine. We decided to introduce GraalVM native image so bring the Java application’s execution environment much closer to the Go application’s environment.

In this case we did not see any substantial improvement in throughput or response time by using GraalVM native image over running the application on a JVM, however the memory footprint was smaller.

t Privacy) is a security algorithm for IEEE 802. It was developed with the intention to overcome the data confidentiality issues with the traditional wired connection. It gave better data protection by encrypting the data transmitted to avoid eavesdropping.

John Ternus, Apple’s VP of Hardware Engineering, the star of today’s show, noted that a “family of chips” were coming, and reiterated that this was just the first step in a transition that is going to take a couple of years. That implies either a different variant of the M1 or a different class of chip all together still yet to come...

The M1 MacBook Pro makes even more sense if it’s just the new “entry-level” MBP. That is, if Apple plans another, more powerful MacBook Pro model which will use a theoretical new chip that say, the iMac or even iMac Pro uses. Or maybe the Mac Pro?!

This is still very possible! But my thinking got thrown in a bit of a loop today when Apple announced the M1 was bound for not only the MacBook Pro, but the MacBook Air and Mac mini as well.³ So that’s Apple’s best-selling and cheapest portable, their best-selling professional portable, and their entry-level desktop machine. It’s a seemingly weird combination. Especially since they kicked off the M1 unveiling talking about how the chip was all about power efficiency and power-per-watt performance. That makes sense for the MacBook Air. It maybe makes sense for the MacBook Pro if these chips really are that fast. It seemingly makes less sense for the Mac mini, which, of course, is a plugged in device. But perhaps it has to do more with development for these new Macs and less for perfecting that particular system.

Matthew Panzarino quipped on Twitter that this M1 MacBook Pro is the new MacBook. And that may actually be correct. When we think about the MacBook now, we think of my beloved super-svelte device which was recently laid to rest. But that wasn’t always the case. For much of its life, the MacBook was actually in between the MacBook Air and the MacBook Pro in terms of size, specs, and price. What if this is a move back in that direction? Certainly it makes more sense from a branding perspective! The Air should be the thinnest and certainly the lightest MacBook. Duh.

In the first round, we ran the test on a “small” machine, in this case a 2.5GHz dual-core Intel Core i7 laptop with 16GB of RAM running macOS. We ran 100 threads with 10,000 loops per thread and a 10 second ramp up time. Java applications ran on JDK 11 and Helidon 2.0.1. Go applications compiled with Go 1.13.3.

Apple’s third event in the past two months was concise — 45 minutes! — and direct. There was no opening act, it was simply all about the Mac. And the Mac proved worthy of that. Afterwards, I did something I haven’t done in quite some time: bought one of the new products immediately.

He’s right, in a way. This wasn’t a big deal, it was a massive deal. If Apple can live up to the performance claims they made on stage today about their new ‘M1’ chip, it will fundamentally alter the laptop landscape. And it portends a shift in the entire personal computer game.

This executable includes the application classes, classes from its dependencies, runtime library classes, and statically linked native code from JDK. It does not run on the Java VM, but includes necessary components like memory management, thread scheduling, and so on from a different runtime system, called “Substrate VM”. Substrate VM is the name for the runtime components (like the deoptimizer, garbage collector, thread scheduling etc.).

In many of the tests we ran JMeter on the same machine as the application under test. There did not seem to be any interference or difference in results if we ran JMeter on a different machine, so this simplified the setup. When we later deployed the applications into Kubernetes, JMeter was running on a remote machine, outside the cluster.

At the same time, it was made clear that the M1 was just a start in terms of what Apple has in store for their silicon plans for the Mac. That thought should send shudders down spines. That’s how good just this “first step” sounded today. Granted, a step without an X or Y axis on performance charts.

Logging seems to be a major performance hit, especially java.util.logging. Because of this, we ran tests with and without logging. We also noticed that logging was a significant factor in the performance of the Go applications.
