[SPARK][GRAPHX] 'Executor Deserialize Time' is too big

Hello, 

I use Apache GraphX (version 1.1.0). And sometime stage which corresponds to this line of code: 

val graph = GraphLoader.edgeListFile(...) 

takes too much time. Looking to EVENT_LOG_1 file I found out that for some tasks of this stage 'Executor Deserialize Time' were too big (like ~10200ms when all others took only ~200ms) 

Does anybody have any idea what it can be?
