Re: [Savonet-users] Starting Over: Recommended Liquidsoap Build?

[Jean-Francois M. <je...@ra...>]

Hello,

I'm also doing tests using VMs. So I currently use VMWare ESXi (bare metal).

What should run on it :
- debian 5
- liquidsoap 0.9.2-2 (from the deb package on the savonet site)
- apache
- php

My liq is input.harbor with a request.dynamic fallback. Dynamic requests are querying a webservice (on an other server) to know what it has to play, it copies the file from our storage system to the local cache directory and cut the song (entry point/extro point) and give liquidsoap the annotate.

We have 10 instances running at max.

VM size (for up to 10 LS) :
- 2 vCPU
- 2 GB ram
- 80 GB HDD

And it's running fine. If I try to start the 11th instance, I have some cut in the stream.

The host server is :
- dual quad core xeon 5400 series
- 32 GB RAM
- 4 x 150 GB SAS HDD Raid 5

HTH
