Milestone 4, a little confusion

sir some version are taking more time for uploading and downloading but after uploading and downloading it shows the expected uploading time and downloading time, should i include these versions also in the file?
if not ,can you clarify why this version is taking too much,is it the memory usage or cpu usage?

As you know some versions are faulty. Use corresponding linux commands to track whether transfer is slow or whether its memory or cpu or some other reason.

i guess its cpu only as its going about 92 during process, but the time is almost equal to benchmark.
thanks .
