Lowering compiling speeds.

[Heisenburger]

Hi, I'm a total noob with computer hardware, but i've decided to build my first custom pc, and I was wondering what kind of things would i have to worry about to try to lower compiling speed, i mostly do java, and sometimes compiling takes 1-2 minutes on some of my larger projects and it can be pretty anoying, so should i invest in  things such as hyperthreading , more ram, etc.

I'm not a Java person but I'm assuming a fast CPU will have most impact on this. 

Get a 5960k if you can wait that long/can afford it.  

Even a 4790k/4770k would probably be enough for Java. 

 

Edit: What is your current CPU?

Compiling is very single threaded so a OC'd i5 would be all he needs.

That's for clearing that up.

Like I said, I have no idea about Java.

AFAIK most compilers only use two cores but I've seen some things use four.

But then you can't do this: http://xkcd.com/303/

1-2 minutes is awesome. Try compiling Chromium from the tip of the source tree.

 

Took me 15hrs and the result leaked memory every ten minutes.

how large is your project? 1-2 minutes seems long. my "largest" project, which may be small compare to yours, compiles in three seconds and its across multiple packages and numerous class files with half a dozen libraries required. even exporting doesnt take two minutes. i'm running on an 8350 @ stock speed.

The best way to reduce compiling times is to open your project, press ctrl+A and then hit delete..

Seriously though. What is your project?

[Syntaxvgm]

1-2  minutes? Really? I have had projects with 10000+ lines in mulltiple classes and it only took me a few seconds..

I mean I can compile basic lighting for small maps on a compiler that limited to 2 threads on a 2.5GHZ 2920xm in that time....

I can render high detailed 4k frames in blender in that time. 

I don't see what would ever take that long unless you are doing something really weird.  :blink:

Please elaborate on how you are measuring 1-2 minutes,What project builder are you using(maven,ant...), is it incremental builds or clean builds timings?, how many lines of code/how many class files do you have?

[tbc]

SSDs.  compilation is always io bound on anything above a c2d

[Midnight]

How big are your larger projects (in terms of lines of code)?
