Our team recently setup a new network and now we are experiencing network latency issues. the flow of traffic is as such: modem -> router -> packet shaper -> cisco3750 switch
from router to packet shaper, I believe we used a cross over cable and from packet shaper to switch, a straight through.
My question is, would using a crossover cable vs straight through cause noticeable lag in the network? The client site is a few hours away and am hoping this is not the case :(
UPDATE: Here are some speed test results
The latency is very noticible during VOIP calls, we have 2 sites and a T1 connecting the two. The above speed test results are from one of the sites.

output for the router interface, the switch interface and the shaping device's interfaces? Being able to see this information should allow someone to provide an accurate answer and not just a guess.
