anchorWithStickyNavbar_LWe7" id="high-level-summary">High level summary<a class="hash-link" href="#high-level-summary" title="Direct link to heading"></a></h2><p>On the performance side, the team ran benchmarks for the the P2P feature and the 1.35.4 release. We finished a prototype for performance data publishing. We almost finished the local deployment backend for the workbench using the new SRE deployment infra. We worked on fixing and improving our data analysis pipeline.</p><p>On the tracing side, the team worked on isolating a critical issue causing message loss in the remote tracing backend. The issue was resolved and we now have proper end-to-end coverage for the scenario.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="executive-summary">Executive summary<a class="hash-link" href="#executive-summary" title="Direct link to heading"></a></h2><ul><li>The new tracing system public release is getting closer, as we're resolving remaining rough edges that are discovered in full-scale deployments. The local benchmarks we ran were already showing improvement relative to legacy tracing, so we expect similar results at full scale.</li><li>The first (local deployment) iteration of benchmarking adopting the new SRE deployment infra is nearly done. We thank Michael Fellinger and Robin Stumm for their assistance. Two further phases remain: CI integration and cloud deployment.</li><li>The benchmarking data publishing prototype is ready. This serves as a springboard for both opening our performance assessment workflow (to support the wider Cardano developer community), and for data provision to the business community. Our next steps are to secure a permanent deployment for this mechanism and to integrate it into the benchmarking infrastructure. This requires collaboration with SRE.</li></ul></div><footer class="row docusaurus-mt-lg blogPostFooterDetailsFull_mRVl"><div class="col"><b>Tags:</b><ul class="tags_jXut padding--none margin-left--sm"><li class="tag_QGVx"><a class="tag_zVej tagRegular_sFm0" href="/cardano-updates/tags/performance-tracing">performance-tracing</a></li></ul></div><div class="col margin-top--sm"><a href="https://github.com/input-output-hk/cardano-updates/tree/main/blog/2022-10-28-performance-and-tracing.md" target="_blank" rel="noreferrer noopener" class="theme-edit-this-page"><svg fill="currentColor" height="20" width="20" viewBox="0 0 40 40" class="iconEdit_Z9Sw" aria-hidden="true"><g><path d="m34.5 11.7l-3 3.1-6.3-6.3 3.1-3q0.5-0.5 1.2-0.5t1.1 0.5l3.9 3.9q0.5 0.4 0.5 1.1t-0.5 1.2z m-29.5 17.1l18.4-18.5 6.3 6.3-18.4 18.4h-6.3v-6.2z"></path></g></svg>Edit this page</a></div></footer></article><nav class="pagination-nav docusaurus-mt-lg" aria-label="Blog post page navigation"><a class="pagination-nav__link pagination-nav__link--prev" href="/cardano-updates/2022-10-28-network"><div class="pagination-nav__sublabel">Newer Post</div><div class="pagination-nav__label">Network Team Update</div></a><a class="pagination-nav__link pagination-nav__link--next" href="/cardano-updates/2022-08-12-sre"><div class="pagination-nav__sublabel">Older Post</div><div class="pagination-nav__label">SRE Team Update</div></a></nav></main><div class="col col--2"><div class="tableOfContents_bqdL thin-scrollbar"><ul class="table-of-contents table-of-contents__left-border"><li><a href="#high-level-summary" class="table-of-contents__link toc-highlight">High level summary</a></li><li><a href="#executive-summary" class="table-of-contents__link toc-highlight">Executive summary</a></li></ul></div></div></div></div></div><footer class="footer footer--dark"><div class="container container-fluid"><div class="row footer__links"><div class="col footer__col"><div class="footer__title">Blog</div><ul class="footer__items clean-list"><li class="footer__item"><a class="footer__link-item" href="/cardano-updates/">Home</a></li><li class="footer__item"><a class="footer__link-item" href="/cardano-updates/archive">Archive</a></li><li class="footer__item"><a class="footer__link-item" href="/cardano-updates/tags">Tags</a></li></ul></div></div><div class="footer__bottom text--center"><div class="footer__copyright">Copyright © 2023 Input Output Global, Inc.
