Hi,
we are running three server (all linux servers) hosted in our area. With the latest server (#3) I see strange latency times despite a faster ping and more hardware power (8GB, 2 cores) than the others.
Server
Ping
Overall latency
Server1
11ms
21ms
Server2
10ms
24ms
Server3
6ms
**27ms **
Is there a way to measure the performance on a root linux server without connected remote clients to see if the problem is caused by the virtual server itself or by network influences?

Hi Jörg - in terms of auditing a VM for causes of latency (that aren't ping), you could try setting up disk I/O or CPU monitoring, but my best guess is that Server 3 is somewhat at the mercy of its VM host perhaps. So if you did find something, it would be hard to know what to do about it. For what it's worth, I'm running syssat, which you could try?
Coincidentally, I recently made the move from running servers on my own co-located hardware at my ISP to their VM cloud. Unlike when I had my own hardware, I'm seeing unexplained I/O spikes and other things from time time. But I'm OK with this as it's literally costing me half what it did before.

Thanks! I assume it could be different root causes. VM host, Network infrastructuce (e.g. DDoS protection, balancing) or/and software installation issue (unlikely).
Therefore, I wanted to install a Jamulus client on the virtual server but did not get through it. Is there a manual (I did not find anything) which describes such a installation (virtual server, no sound hardware, jack configuration for this setting)?
