Considering that many servers these days are configured to not 
respond to ICMP echo requests, that may well be pointless.

It may be possible to get a bit more useful information using 
tracert, that will hopefully give an idea where any excessive latency 
is occurring. Then again, it may not.

A single invocation of tracert may not give any real useful data 
either as it only looks at the current conditions and reports the 
response latency between hops as they are when the test is run. 
Network traffic can change these things dramatically over time. It is 
possible that one time you get a clean, fast run and another you get 
indications of a slow down.

Now it sounds to me that the OP is seeing a problem with the TCP/IP 
sessions between the client and server being closed prematurely. Why 
that is occurring is unclear. It is probably going to take some 
low-level analysis of the packets to determine what is going on.
