Server Specs

We need more data. Based on what you have provided, it might be fine for a medium-sized server provided that you perform careful optimization.

 

With 4 GB of RAM, you'll be extremely limited. Go with a Xeon E3 V3 or Intel Core i5/i7 (latest gen). It should both be cheaper and fast (in most scenarios).

 

You should go with an E3 which has a faster clock speed since MC will only use one of those threads.

 

Link to what?

 

Whats your budget? If It's small you can probably pick up something better from KimSufi, check out the KS-4; It's a powerhouse and is in stock right now!

 

Both of the servers you posted are pretty rubbish, they'll work for smaller servers, sure, but the KS-4 is so much better, and gives you much more future proofing.

It's sold out quite often, so I see your point, but is available right now, if I was you I'd grab one now.

 

Rubbish for Minecraft, as It's primarily single threaded. Good single thread performance is what you're after.

Didn't even know Intel manufactured Dual Core E5's? Perhaps you mean Dual E5's?

 

Well the KS-4 is the best bang for your buck for low end servers, but if you're after more power any of the E3's will suffice, personally I'd grab the SSD variants, but thats up to you.

 

The clock speed, core count and processor line of the CPU isn't really very useful. We need to know the exact model of the thing or we can't help.

 

What's your budget (and how much are you paying right now for the machine, that's in your post)? I honestly suggest you to use ReliableSite or something along those lines, a Kimsufi KS-4 will be great for you.

 

The Xeon E5s never had a Dual Core. It's most likely an old Dual Xeon E5100.

Stick with a Xeon E3 V3 for Minecraft.

 

Thank you for the recommendation.
