I generated the attached file group_perf_e63e4961f27a9a6a4b9ae5b84c0d7e67e2f9d4db.txt which contains information about the performance of SBE relative to classic for our $group benchmarks at githash e63e4961f27a9a6a4b9ae5b84c0d7e67e2f9d4db. I used the following query against the PerformanceReports Atlas cluster:
let cursor = db.getSiblingDB("perfreports").sbe_perf_latest.aggregate([
|
{$match: {tags: "group"}},
|
{$sort: {signed_percent_change_stable: 1}},
|
{
|
$project: {
|
task: 1,
|
test: 1,
|
measurement: 1,
|
args_str: 1,
|
value_measure: 1,
|
stable_mean_baseline: 1,
|
stable_std_baseline: 1,
|
signed_percent_change_stable: 1,
|
signed_z_score_change_stable: 1,
|
tags: 1
|
}
|
}
|
]);
|
|
while (cursor.hasNext()) {
|
printjson(cursor.next());
|
}
