Response time for a ping command

[John Garrett]

What are accecptable response times for a ping response on a LAN?  I have a workstation that when I ping the machine I get responses up to 250ms.  Is this accecptable or is that to slow?

Thanks

Between hosts on the same (physical) LAN?

If so, 250ms does seem rather slow, although many hosts treat ping replies with low prority, so a really busy host's ping responses may jump quite a bit.

High latency like that, could also be indicative of queuing latency, although most LAN devices don't allow for such queuing delays, at LAN bandwidths, before packets are dropped (from lack of queue/buffer space).

Hi John, 

The baseline for what is acceptable varies somewhat depending on connection type and ping destination relative to the device, also the topology of the LAN itself. 

In general, though, 250ms is quite long. The workstations on my network can ping the local router in under 10ms. You likely have an unacceptable amount of latency in your network. 

Best of luck,
