YCSB Benchmark Results for Cassandra, HBase, MongoDB, Riak
A recent slide deck presenting results of the YCSB a new benchmark run against the latest versions of Cassandra (0.6.10), HBase (0.20.6), MongoDB (1.6.5), and Riak (0.14.0): Some of the results are striking, so I cannot wonder if there weren’t some configuration issues. Update: A few users that had more luck reading the details on the slides have pointed out that this is not the YCBS benchmark, bu

LevelDB Benchmarks
Google, July 2011 In order to test LevelDB's performance, we benchmark it against other well-established database implementations. We compare LevelDB (revision 39) against SQLite3 (version 3.7.6.3) and Kyoto Cabinet's (version 1.2.67) TreeDB (a B+Tree based key-value store). We would like to acknowledge Scott Hess and Mikio Hirabayashi for their suggestions and contributions to the SQLite3 and Kyo

September 15, 2004 Petr Cimprich There was one dominant XML parser in Perl a few years ago; parsing an XML document was synonymous for using the XML::Parser module.

Traditional Perl modules for XML processing were built on the top of XML::Parser
