It's encouraging to see the C implementation performs well.

As per the graphs, the performance gap between the two implementations
implementations (Java/C) and between the two parsers (Guththila/Libxml2)
narrows down as the data set size increases. There could possibly be two
reasons for this.

1. Increased bandwidth utilization (as indicated in one of those graphs)
adds more network latency.
2. The engine is less efficient in processing large data sets compared to
small sets.

It would be interesting to see which of the above two is the dominant

If it is the first one, one approach may be to introduce message compression
techniques for large data sets further improve performance. If it is the
second one, one possible direction is to see if the same data set is
repeatedly processed and take preventive actions (e.g. caching, annotations,
