Then someone realized it could work on X as well, and it soon became the default. LevelDB vs SQLite: What are the differences? ... Symas LMDB. It is an extraordinarily fast, memory-efficient database which is developed for the OpenLDAP Project. With memory-mapped files, it has the read performance of a pure in-memory database while retaining the persistence of standard disk-based databases.LMDB reuses the space freed by deleted entries instead of compacting the store, which avoids the complexity and performance impact of compaction (trading off disk space in some situations). LevelDB. LevelDB read performance is good, with this 2011 benchmark showing improvements over engines like SQLite. ActorDB is a distributed SQL Database designed around having to do the least possible inter-server synchronization. ActorDB has two distinct engines: SQLite for running SQL queries which uses pages to store data and LMDB for storage in an append-only style where checkpoints are replaced with cleanups that only free up space for later use.Bug 1086784 - Proposal: Replace Berkeley DB with LMDB.

Website zip file downloadSQLite is built from over one hundred files of C code and script spread across multiple directories. The implementation of SQLite is pure ANSI-C, but many of the C-language source code files are either generated or transformed by auxiliary C programs and AWK, SED, and TCL scripts prior to being incorporated into the finished SQLite library. High performance subdivision surface libraries OpenSubdiv is a set of open source libraries that implement high performance subdivision surface (subdiv) evaluation on massively parallel CPU and GPU architectures. This codepath is optimized for drawing deforming subdivs with static topology at interactive framerates. The resulting limit surface Memcached is high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load. Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering.

Google has provided benchmarks comparing LevelDB's performance to SQLite and Kyoto Cabinet in different scenarios. LevelDB outperforms both SQLite and Kyoto Cabinet in write operations and sequential-order read operations. LevelDB also excels at batch writes, but is slower than SQLite when dealing with large values. Packages included in Anaconda 4.3.1 for Python version 2.7¶. Python version: 2.7. Number of supported packages: 521 Aug 17, 2013 · I didn’t do any performance analysis for non-sqlite benchmark results, and wouldn’t draw too many conclusions about the results. These results do seem to confirm though that the HDBC library adds a fairly significant overhead to database row access. Comparing HDBC against sqlite-simple, we get 105K vs 1.8M rows/s.
