+
+## Agenda
+
+## Announcements
+
+*Extracted from **benchmarking-agenda** labelled issues and pull requests from the **nodejs org** prior to the meeting.
+
+* Jamie, on calls with folks at Oracle and other academic institutions. They seem interested in 
+  benchmark development and analysis validation. Potential of a coalition forming out there. 
+  Early stages but some have additional benchmarks (some use ACME air) that they would 
+  be willing to contribute them back.  Also interest in contributing data formats, configurations,
+  etc.  Michael any reason they would not want to drive it as part of this work. Jamie Not sure.
+  They’re definitely interested in using benchmarks, and an easy way to feed them in.
+* Jamie has undergrad who is studying metrics used by N|Solid and Node Clinic to see
+  if there are any other metrics that we should be collecting. For example event loop blocking 
+  time and gc metrics. Data for diagnostics vs. data for workload fingerprinting.
+
+### nodejs/benchmarking
+
+* Investigate the time taken, and number of benchmarks in core [#225](https://github.com/nodejs/benchmarking/issues/225)
+  * We don’t have Gareth so we’ll skip.
+
+* Require cached pref much lower [#202](https://github.com/nodejs/benchmarking/issues/202)
+  * Narrowed down to specific commit
+  * Unclear whether we’re measuring the right thing?
+  * Unclear what the benchmarking framework is doing?
+  * Uttam will continue to investigate.  
+
+* Add Ghost.js workload to the benchmarking [#159](https://github.com/nodejs/benchmarking/issues/159)
+  * Next on Uttam’s list.   
+
+* Simplify multiple scripts, logs in nodejsbenchmarking infrastructure [#155](https://github.com/nodejs/benchmarking/issues/155)
+  * Have been attending meeting to see if we can re-use code from somewhere else
+  * Does not sound like there is something else that would run our set of benchmarks in a
+    consistent manner
+  * Jamie or undergrad will start working on this soon.
+
+* Candidate benchmarks [#6](https://github.com/nodejs/benchmarking/issues/6)
+  * Related to announcement above, none of the people Jamie has talked to have
+    concrete additions to make.
+  * Oracle folks may have something benchmark that we might be able to use.  Also
+    possibly one from the BBC (??).
