# AS-IS performance profile
|
|
|
|
The startup path performs network-dependent synchronization when installer/update is used, writes generated LISP files, starts a batch and may load 20 assemblies sequentially. No timings were collected; claims about latency, parallelism, cache hit rate, or behavior under unavailable network are `UNKNOWN`.
|
|
|
|
| Source-level observation | Evidence | Performance implication | Confidence |
|
|
|---|---|---|---|
|
|
| Installer recursively copies selected catalogs and can delete files/directories | `All_Serv_Install/Form1.cs` copy path | filesystem and potentially network traversal; UI blocking behavior requires measurement | CONFIRMED |
|
|
| Updater computes MD5/control sums and replaces local files | `All_Serv_InstallUpdater/Form1.cs` | repeat hash/read/copy work; no measured count or time | CONFIRMED |
|
|
| Bootstrap emits one generated loader command per selected installed catalog | `P_Serv_Starter/Program.cs` | sequential startup work grows with selected modules | CONFIRMED |
|
|
| OrthoLoader sequentially `. _netload`s 20 configured modules | legacy loading audit | 20 managed loads before all functionality is ready | CONFIRMED |
|
|
| Repeated load on document/workspace events | no complete event evidence | cannot assert | UNKNOWN |
|
|
|
|
No measured count is claimed for network requests, full copies, UI waits, `Process.WaitForExit`, `Thread.Sleep`, or repeated document-level loading. Those are measurement subjects, not observed facts.
|
|
|
|
## Measurement plan (proposed)
|
|
|
|
| Scenario | Start | End | Proposed metrics |
|
|
|---|---|---|---|
|
|
| Cold start | launcher action | Ribbon ready | elapsed time, files hashed/copied, bytes, NETLOAD count |
|
|
| Warm start | launcher action | Ribbon ready | cache hit, network requests, elapsed time |
|
|
| Offline start | launcher action with network unavailable | Plant prepared/started | valid cache use, retry count, user status |
|
|
| No-update start | catalog read | launch prepared | manifest comparison and file operations |
|
|
| Update start | catalog read | activation complete | staging time, hash time, atomic switch time |
|
|
| Rollback | rollback request | previous pointer active | elapsed time and success/failure |
|
|
| Plugin readiness | Plant process created | Initialize and Ribbon ready | process-start, entry-load, command/Ribbon timestamps |
|
|
|
|
Targets are **PROPOSED** until baseline data is collected: one entry NETLOAD, zero network assembly loads, zero in-place replacement of active package files, and no repeated full copy on a valid no-update start.
