Improve Quartus II Compilation time (hardware)

[Altera_Forum]

Hello my design is taking a long time to compile and i need to improve it. 

 My computer is an i5 with 4gigs of ram. I am thinking about buying a computer with two xeon processors, will it decrease my compilation time? Currently is taking me 4 hours to finish a compilation;  Can Quartus II handle well more then one processor?

Do you have enabled Smart Compilation? Quartus 12 is more fast..

anyone? I am waiting to buy a new hardware based on the responses

To use more then one processor you have to buy subscription edition

i have the subscription edition.

Unless things have changed in 12, Quartus uses only one processor when real work is being done (fitting for example). I have 6 cores and only one of them gets heavily used. So, buy the fastest processor you can get with the most cache. A lot or RAM does not hurt either. 

 I assume that dividing the fitting process into multiple threads is still an illusive problem for Altera (and others).

We've seen the greatest improvement in build time by moving to the fastest memory you can afford. 

 We ran several benchmarks builds using a core i7 2600 overclocked to 4.1GHz and several different standard memory modules (PC3-10600, PC3-12800, PC3-14900).  Overclocking the CPU made a marginal improvement on the build time. Overclocking the memory also improved the build time.  By going from a standard core i7 2600 at 3.4GHz with PC3-10600 to overclocking the core i7 to 4.1GHz and swapping out the memory for PC3-14900 (also slightly overclocked), we took our 218 minute build down to around 73 minutes.   On a side note, running the build in command line mode also improves the build time.
