Let's consider A (client) and B (server) where A makes download from B.

How much can a bad routing from A to B affect the download speed ?

For example A does a tracert to B and get a response of 10 steps where the avg ms is around 300 with 10% packet loss at the 4 step and when the connection is normal the avg from A to B is 10 ~ 30 ms.
Could this sort of impact reduce A download speed drasticaly or as long as both side and routes have enough link for the full speed of A from B and vice-versa it should maintain the same speed ?
Besides tracert and the ping analyse of A to B what else is used to identify the problem ?

If you need extra information please let me know.
