RsDataService::retrieveNxsMsgs() issued one prepared statement per requested message id. Each one rebuilds the SQL text, runs a full sqlite3_prepare_v2 (SQL parse plus query planner), allocates a cursor and finalizes it -- an overhead that dominates the actual row lookup, and is paid thousands of times whenever a request covers a large id set. Pack the ids into "msgId IN (...)" batches of 500 instead. The message ids are plain hex strings so they need no escaping, and the batch size keeps both the generated SQL and sqlite's expression tree small. The previous commit removed this path for unfiltered whole-group requests; this one covers everything else: a channel post with its comments, forum threads, and any filtered request. retrieveGxsMsgMetaData() still has the same one-query-per-id shape in its non-empty branch, but there each id is first looked up in the meta cache, so the remaining queries are only the cache misses. Left alone for now so it can be measured on its own. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

== RetroShare library
RetroShare is a decentralized, private, secure, cross-platform, communication
software.
RetroShare functionalities (file sharing, chat, messages, forums, channels...)
are implemented under the hood by libretroshare which offers a documented C++ and
JSON API.
While RetroShare is an application on its own, libretroshare is meant to be
used as part of other programs, some of them are
https://retroshare.cc[RetroShare-gui],
https://retroshare.cc[RetroShare-service],
https://gitlab.com/elRepo.io/elRepo.io-android[elRepo.io]
(let us know if there are more).
=== Continuous integration

=== Developer Documentation
All public API methods are documented with Doxygen comments, so the most updated
way to read documentation is reading those comments in `src/retroshare/`.
To use libretroshare as part of your Android application we suggest to add our
maven repository, and then specify the variant and version that fits your needs
as dependency. RetroShare is then exposed as an Android Service as you can see
at https://gitlab.com/RetroShare/libretroshare/-/blob/master/src/rs_android/org/retroshare/service/RetroShareServiceAndroid.java?ref_type=heads[RetroShareServiceAndroid.java] start it and then interact with it
via RetroShare JSON API.
