re:development hardware specs that worked for you

Hello,

What is the specs of your PC if it works for you well, for productivity, speed, etc. when developing android apps, or JEE applications?

e.g. sdd drive, 8 gig ram, etc.

Sometimes we need stuff like eclipse, mysql, etc. running on our PC.

What specs satisfied you?

I use an entry level MacBook Air for most of my development work. It's an Intel Core i5, 4GB RAM, 128GB SSD. Works like a dream.

If I were to wish for something else it would be a large external monitor to hook it up to at home.

Thanks for the tip Tim.

When many apps are running, I am starting to feel I am back to working on the IBM Mainframe client console. I have to blink many times before cursor moves one step. (specs: hdd, 4gig ram)

Memory is more important than processor speed and disk space. If you can up your amount of memory, that will yield the biggest improvements. Even with 16G, I bump my head now and again.

That's hardly a full spec for anyone to draw any conclusions from. Lots of open questions: What CPU? How old is the machine? Who makes it? Disk capacity? Is the disk full? Windows? Mac? Linux? Do you have a load of junk installed on it?

You see, there's lots of reasons why a machine runs slow. I recommend investigating what the bottleneck is. What resource have you saturated while running all your stuff.

OS: Windows 7 64-bit
Free Hdd space: 100 gig
RAM: 4gig

Basically, although it is my personally-owned pc, I dont install much software as I need it for development. I make sure I dont set software as auto-windows-start-as-service.

During Slow down:
Memory usage: 1 gig occupied by eclipse, mysql, firefox, chrome, etc. Even when I close the 2 browsers, the slowness is still there.
What else is running: When I run eclipse and mysql, it already starts to slow down. Spring STS also is very slow (not sure if isolated to STS).

I think, just like Bear said, increasing that RAM, and then converting the HDD to SDD, will help a lot.

It will be much more cost‑effective (and much easier) to add extra RAM than to buy an SSD.

Thanks. I will try out and see.

I am surprised you are running slowly with that spec, even without upgrading.

Don't be too sure about effectivity. A project at work used to take a colleague of mine 15 minutes to build (mainly because of 4 GWT applications with 6 browser profiles each). After switching to an SSD his build time went down to less than 4 minutes.

An SSD will help with anything that's heavily file-oriented, such as a build. But more memory will improve overall performance for everything.

That still could be related to insufficient RAM if swap/page file on the HDD was being used extensively and the SSD sped-up the swapping

Is definitely say RAM and SSD will fix the majority of slow downs. My dev machine has 28GB of RAM and a 500GB SSD. I definitely notice the difference when I use my much more modest home pc.

They don't help network issues though. If I make the mistake of saving files to a network share things slow down a lot, particularly checking out from repositories.

That do sound like a dream machine.

For today, I increased my memory by 4 gig; it is now 8 gig (sadly, my motherboard can only take up to 8 gig).

It is now:
i5 quad core cpu
8 gig ram
hdd

I opened applications and here are their MEMORY allocations:
mysql: half gig
Spring STS: half gig
firefox 300mb
eclipse: 300mb
oracle db: 175mb
sqldeveloper: 170mb
chrome 100mb (many instances)

sts and mysql seems huge.

anyway, things look better. Maybe I can later just upgrade to a better motherboard, more cpu core, higher RAM, and SSD when opportunity arrives.

I wonder if that Windows Task Manager statistics on Physical Memory matters.
It has:
Total:8gig
Cached:3.5 gig
Available:3.5 gig
Free: 0

I assume what matters above is the Available.
 
Don't get me started about those stupid light bulbs.
