Issues & Decisions
| Issues | Notes | Decisions | |
|---|---|---|---|
| 1 | KPI for De-registration of 100 CM-handles | This was mentioned. Was this ever agreed, is this a valid use case that needs to be covered together with the Registration ? | Not priority for now, but acceptable if we match the registration req. |
| 2 | DMI delay | Could we get some feedback on DMI-delays for other use cases as not mentioned in FS document | Awaiting for ETH feedback AP On Kolawole Adebisi-Adeolokun and Csaba Kocsis |

Provided | |||
| 3 | Number of instances In some cases, ETH have used 2 instances, can we verify the number of instances for each use case. Some of the req were defined per instance and resources used : Identify which of these ? | Agreed to; CPS use 1 instance currently, but should focus on aligning performance with 2 instances for all use case | |
| 4 | Input Load Distribution the CM-handle search and ID search | Currently has 5 parallel request between them distributed at 2.5 each. This fractional distribution isn't feasible for parallel processing; the load should be allocated as whole numbers. Load needs to be distributed at. Would it be acceptable to adjust this distribution to either 2 or 3 parallel requests each (and vice versa ) without any negative repercussions? Agreed to do 6 parallel request combined total and divide the load to 3 parallel request each | |
| 5 | Regarding CM-handle search and ID search | FS only identified Module performance, are there any testing done towards a combined search of properties and modules in a single query Confirmed no other testing was previously done on this..... CPS have the capabilities to do mixed testing. ETH tbc on if they want to consider this ( Csaba Kocsis ) |

Characteristics
It is proposed that reported characteristics will be used as a baseline for NCMP when agreed and sign-off.

100 ms to get module references
1000 ms to get module resources

| De-registration is currently not mentioned in Stone Tablet KPI or FS, however we have agreed to match the performance of registration for now as de-reg is also not a priority at this point in time |

- This is for mixed TCs
- Single KPIs will be monitored in NCMP owned pipeline with our performance every day(2 hrs interval) - Performance
