Sorry for that, it's the usual problem with renaming files. I could never get 
post-review to work with my checkout. Maja and I were thinking it would be 
helpful to have some guidelines on the website on how to create patches and 
(for committers) how to apply them (I use "patch -p0 -i" currently).
For now, can you please manually rename TestMutateGraphVertex.java to 
TestMutateGraph.java after applying the patch? That should fix the build.

Other than that, this passes mvn verify and pseudo-distributed mode tests with 
4 tasks, both with RPC and Netty, with/without out-of-core enabled and with 1 
or 2 max partitions in memory.
You can find some benchmarks here 
(https://issues.apache.org/jira/browse/GIRAPH-249?focusedCommentId=13435280&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13435280)
 and in the following post.

Yes, since doRequest directly adds to PartitionStore.
