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.

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?

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:

muh specs 

Gaming and HTPC (reparations)- ASUS 1080, MSI X99A SLI Plus, 5820k- 4.5GHz @ 1.25v, asetek based 360mm AIO, RM 1000x, 16GB memory, 750D with front USB 2.0 replaced with 3.0  ports, 2 250GB 850 EVOs in Raid 0 (why not, only has games on it), some hard drives

Screens- Acer preditor XB241H (1080p, 144Hz Gsync), LG 1080p ultrawide, (all mounted) directly wired to TV in other room

Stuff- k70 with reds, steel series rival, g13, full desk covering mouse mat

All parts black

Workstation(desk)- 3770k, 970 reference, 16GB of some crucial memory, a motherboard of some kind I don't remember, Micomsoft SC-512N1-L/DVI, CM Storm Trooper (It's got a handle, can you handle that?), 240mm Asetek based AIO, Crucial M550 256GB (upgrade soon), some hard drives, disc drives, and hot swap bays

Screens- 3  ASUS VN248H-P IPS 1080p screens mounted on a stand, some old tv on the wall above it. 

Stuff- Epicgear defiant (solderless swappable switches), g600, moutned mic and other stuff. 

Laptop docking area- 2 1440p korean monitors mounted, one AHVA matte, one samsung PLS gloss (very annoying, yes). Trashy Razer blackwidow chroma...I mean like the J key doesn't click anymore. I got a model M i use on it to, but its time for a new keyboard. Some edgy Utechsmart mouse similar to g600. Hooked to laptop dock for both of my dell precision laptops. (not only docking area)

Shelf- i7-2600 non-k (has vt-d), 380t, some ASUS sandy itx board, intel quad nic. Currently hosts shared files, setting up as pfsense box in VM. Also acts as spare gaming PC with a 580 or whatever someone brings. Hooked into laptop dock area via usb switch

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?

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

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