Howard Chu @ SymasNote to <a href="https://mastodon.social/tags/HPC" class="mention hashtag" rel="nofollow noopener" target="_blank">#HPC</a> software researchers: Oracle invited us to their HQ to benchmark and profile <a href="https://mastodon.social/tags/LMDB" class="mention hashtag" rel="nofollow noopener" target="_blank">#LMDB</a> on their 1024 core servers. Those tests showed no bottlenecks in OpenLDAP or LMDB, and one bottleneck in their Solaris kernel. If you really need to make your software work well with LMDB on 10K CPU cores, give us access to your system and profiling tools and we'll identify your actual problem areas.
