<div> the sizing really depends on your test scaling requirements.</div>
<div> For example my own test infrastructure is a couple builders + 4 nodes for VMs (each has 256G RAM), 160 VM pairs in total,</div>
<div> and on a particularly busy day another 80 VM pairs can be added. This is to ensure speedy feedback to developers.</div>
<div> You can operate a much smaller scale testing system if you want, just keep in mind what is the longest running test would take</div>
<div> to understand how many patches could be tested in parallel (sometimes patch bombs result in 20+ patches submission at the same time).</div>
<div> Here’s stats for last 30 days. <span style="color:unset; font-family:unset; font-size:unset; font-variant-caps:unset; letter-spacing:unset; text-align:unset; text-indent:unset; text-transform:unset; white-space:pre-wrap; word-spacing:unset; text-decoration:unset"><a href="" target="_blank">hxxps://imgur.com/lk2ogJv</a>
1 item means single patch n processing. time in testing for a patch is typically about 3.5 hours.</span></div>

Maloo is just one place to link to to actually let people see the results, but you can link to external resources too<br>
like e.g. gatekeeper janitor helper does or assuming the information is small enough it could be entirely contained<br>

<div>Ok, understand now. Is there any other reference external CI that posts results to Lustre gerrit now?</div>

</div>
Currently there are:</div>
<div>- checkpatch and Misc code checks (smach) that post their results as 100% comment only. they share codebase pretty much</div>
<div>- the Janitor (also started with above codebase but got changed and extended a lot)</div>
<div><br>
</div>
<div>There was external interest in the past to post results to gerrit but it never materialized in the end</div>
