What latency is normal for a Citrix Netscaler - Virtual Appliance
Posted on 2013-12-05
HI There,
We have a customer who is running a citrix solution and while it performs pretty well I've noticed a large amount of latency from the Citrix Netscaler, even from a local device.
Anything else on the network pings at <1ms but the Netscaler is all over the place.
When there are about 50 users connected I've seen it spike randomly to 1000ms, which translates to lag within the Citrix Session.
In my troubleshooting we have found that the latency gets worse the more people are connected.
Does anyone know why it does this, and if there is a good solution to getting it fixed? Or is it something I should not even worry about?
I've attached a screenshot of what I am referring to.
Thanks in advance,
Ben

I assume you're talking about a physical appliance, not a VPX ?
Such high latency is not normal. Should you worry? If users complain of session lag, then of course yes.
I would recommend you start with basic network troubleshooting by your network admin. Check for errors on the switchports the device is connected to etc, flow control, network saturation, ...

We are using Netscaler VPX.
@ sekarc4u - Are you talking about enabling QoS within our Vmware environment or on the Netscaler itself?

One small information, in our environment the architects came up with a parameter. For a user to have seamless experience in VDI, the latency should be less than or equal to 300ms. Any latency beyond this will be detected as slowness or shaggering experience by end user.
