------------------------------------

Hello Yoon.

As you said, I performed the test by increasing the task
However, because there is not enough memory in the test PC, I tested the task by increasing only 3.

[Environment]
- H/W : Intel Core i5 1.80Ghz*4Core 4GB
- TestCase : PageRank, 2, 3task(opt:-Xms1024m), 20,000vertices

[Results - 2 Task]
|| vertices || edges per vertex || Hama 0.7.0-SNAPSHOT(AS-IS) ||  Hama 0.7.0-SNAPSHOT(Netty) ||
| 20000 | 100 | 55.205 | 55.155 |
| 20000 | 200 | 94.168 | 94.478 |
| 20000 | 300 | 139.303 | 139.239 |
| 20000 | 400 | 208.391 | 205.311 |
| 20000 | 500 | Job failed. | Job failed. |

[Results - 3 Task]
|| vertices || edges per vertex || Hama 0.7.0-SNAPSHOT(AS-IS) ||  Hama 0.7.0-SNAPSHOT(Netty) ||
| 20000 | 100 | 49.189 | 52.171 |
| 20000 | 200 | 88.166 | 88.152 |
| 20000 | 300 | 124.310 | 124.306 |
| 20000 | 400 | 169.424 | 169.875 |
| 20000 | 500 | 220.916 | 220.944 |

This test showed similar results
But, often had unusual results.
I think it needs further testing for reliability.

> The current RPC server code is too complex and there are some unnecessary code
> So, It seems good to add implementation of RPC such as netty
