Too low Performance when running PageRank and WCC on Graph500

shepherdkingqsp@...
 

Hi there,

Recently I am trying to measure Janusgraph performance. When I was trying to run benchmark using Janusgraph 0.5.3, I found too low performance when testing pagerank and wcc.

The code I used that you can refer to:
https://github.com/gaolk/graph-database-benchmark/tree/master/benchmark/janusgraph

Data:
Graph500

The environment:
Janusgraph Version: 0.5.3 (download the full release zip from janugraph github)

The config of Janusgraph (default conf/janusgraph-cql.properties)
gremlin.graph=org.janusgraph.core.JanusGraphFactory
storage.backend=cql
storage.batch-loading=true
storage.hostname=127.0.0.1
storage.cql.keyspace=janusgraph
cache.db-cache = true
cache.db-cache-clean-wait = 20
cache.db-cache-time = 180000
cache.db-cache-size = 0.5
To be more specific, I ran Khop with it and got reasonable result.

K-Hop

Latency

1-Hop

23.42

2-Hop

16628.49

3-Hop

1872747.62(2/10 2h Timeout)

4-Hop

889146.03(8/10 2h Timeout)

5-Hop

10/10 2h Timeout

6-Hop

10/10 2h Timeout

But when I ran wcc and pagerank, I got 3 hours timeout either.

Could you somebody help find the reason that I got low performance?
