How Much Ram Does My Minecraft Server Need?

Hello, I'm soon hoping to be hosting a 24/7 mine craft server but i don't know how much ram i need i will have max 20 players and about 20 plugins will 2g of ram do? If Not what stuff e.g amount of players and plugins can i run with 2g? Thanks For your help.

 

Take a look at these tables on Minecraftwiki.net: http://www.minecraftwiki.net/wiki/Server/Requirements/Dedicated

 

From my experience, if your plugins are small they should be ok with 20 slots and 2GB RAM. I run 40 slots and 52 plugins on 3GB of RAM. To date, I have yet to have an "Out of memory" error. Knock on wood...

 

Yes, no problem. I had 30 players on the other day with 1GB. I run 22 plugins or so.

 

Would it lag with 2g of ram?

 

Should be fine. My own server have 4gb ram with 20-30 people in the weekends and i'm not even going through 1.5gb with 38 plugins.

 

Thanks For The Help.
