Slow buffering in Spark

[timhbf]

I recently found that streaming a large file (200MB up) through Spark takes long time for the song to start playing, and the buffering is very slow, it cause long pause many times within one song. Anybody experiencing the same?
Ended up I figured out what happened and it's very strange. It's about networking connection, I've a 2 gigabyte Ethernet ports in my PC, the connection status is 1Gbps. If I force it downgrade to run 100Mbps, the problem gone. Any idea? Is it Spark problem?

If in doubt, blame Spark
Seriously, this is really strange. Nothing else changed? Have you reported the problem and solution to Devialet?

Hmm, one of the network connections not set at full duplex?

I really blame spark and have reported to Devialet, no solution yet. It was not happened before.

Just Googled no half duplex with Gigabit Ethernet, all full duplex
