Slow VertexIter using S3

[Muniraju Pulipalyam]

Hi All,

 I have a graph of 5000 vertices constructed and stored in S3. I have two 
issues:

  1.
 When I try to iterate over it using VertexCollection, VertexIter is very slow. 
Works just fine using local storage. It takes a long time in: 
readers_.emplace_back(vertex_info, pg, prefix); in graph_reader.h. Is this a 
known problem? I am running from a compute instance which is in the same 
region/network as the S3 instance.
  2.
Why does graphar::GraphInfo::Load require '?' In the path for S3 always? In 
PathToDirectory method, you are finding suffix of '?'. If it is not found, 
shouldn't it be just ignored?

Thanks,
Muni
