/prog/ - Java — World4ch

Name: Anonymous 2010-02-27 17:35

The university professor that is teaching us Java said Java is only 10% slower than C.

So who lied? Him or you, /prog/?

He's lying, Java is actually faster than C when used correctly.

I've lied on /prog/ so much, I don't know any more. Him, probably.

It's too generic to take as truth.

What machine are you running the programs on?

    We use a quad-core 2.4Ghz Intel® Q6600® machine with 4GB of RAM and 250GB SATA II disk drive.

    The out-of-date measurements used a single-processor 2.2Ghz AMD™ Sempron™ machine with 512MB of RAM and 40GB IDE disk drive; and a single-processor 2Ghz Intel® Pentium® 4 machine with 512MB of RAM and 80GB IDE disk drive.
What OS are you using on the test machine?

    We use Ubuntu™ 9.10 Linux Kernel 2.6.31-19-generic

    The out-of-date measurements used Debian Linux 'unstable', Kernel 2.6.18-3-k7 and Gentoo Linux gentoo-sources-2.6.20-r6

So when im installing something using an installer written in C that takes 60 minutes to install, the same in java would take 66min? FUCK THAT SHIT

Don't ask us. Go code a benchmark yourself and run it in both.

For trivial tasks, Java's probably only about 10% slower. For anything complex, it really adds up.

This. Using a generic benchmark is no better than just guessing.

OK, in some situations I can see how Java can be faster than C. Java runs far, far slower than C when running large programs(assuming that the C programmer has half a brain). The question is, what do you want to program?

My benchmarks come out at about 1.6x slower when running a similar program from the JVM. Also, Java takes a fuckload longer to startup than C.

In practice Java will be about 20% slower than C, assuming a pure C implementation (no SIMD assembly) and you're not doing a ridiculous amounts of array ops (though, the JVM is only getting better at eliding bounds checks these days).

In all honestly, unless you're performing shitloads of matrix operations or using copious amounts of S?SSE[1-4] assembly, you probably aren't making an application that'll see a speed difference between the two.

Now memory usage and start up times; Yea, Java sucks shit at that.

I am a computer programmer, which means I'm fat, nerdy, and have a tiny cock. I got AIDS from paying a cheap whore to fuck me, since I have no love in my life.
When the doctor told me, I went to the only thing I knew -- SICP.
I slammed my penis between two copies of SICP. It swelled up to twice normal size and fell off. I was worried.
I woke up the next day with incredible abs, a 14" rod of steel, and no HIV. I'm now an adult movie star, banging porn stars.
Thank you, SICP!

Java is also quite fast at string handling, particularly concatenation. It is possible for it to exceed C in performance.

But it doesn't stop Java from gargling chocolate cock.

Also it has recently gotten incredibly good at client-server operations... I personally don't believe the benchmarks, but they were in a linux journal, and they don't have as big of a hard on for Java as they do C.
