[raidenninjamgs4]

Greetings

I have installed Shoutcast in a VPS, and i want to know what would be the appropriate number of users that would allowed my VPS. Here are the details:

1 vCPU Core Intel Xeon E5-2650L*v4
1GB Memory
20GB SSD Disk
2TB Transfer

I'm planning on transmiting with Winamp DSP plugin, MP3@128Kbps.

Thank you.
