Network latency caused by incorrect cable?

Question

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.

In your question's scenario : No. It would either work (meaning that your ports have Auto MDI-X, which is built into Gigabit Ethernet, IIRC) just fine, or not work at all.

Which means the cause of your problem is elsewhere.
