Toubleshooting ping output

[thiyagarajankalaiselvan]

I'm facing a performance issue when users trying to download files from the remote server. I have been trying to figure the cause of the performance issue:
I have found strange output from the user Laptop. I have requested the user to the extended ping to any server with various packet size.

I have got the output as below packets are getting droped. How can I fix this issue?
ping -s 1400 google.com

--- google.com ping statistics ---
8 packets transmitted, 8 received, 0% packet loss, time 7011ms
rtt min/avg/max/mdev = 103.274/106.396/107.925/1.322 ms

If we are doing the normal ping it seems good. without any issues.

Does this cause the performance issue of bulk transfer traffic?

how can I fix this issue?

Anyh help would be highly appreciable.

Hi,

8 packets transmitted, 8 received, 0% packet loss, time 7011ms

  Where are the packet drops?

what happens with lower size pings and higher size pings, what is the path MTU between your host and the server pinged?

Regards.

hi,

your latency of 7011 ms seems to be very high. your links either on switch trunk or router WAN link could be congested. double check on speed/duplex settings and MTU sizes on your ports. you could also perform packet sniffing to check what traffic causing any congestion.

Hi ,

You can maybe  use pathping  to see where are the bottlenecks.
