Running against the Helium release, I can see so many invocation calls to the inventory while profiling.</p> <p>Please see attached for the profiling snapshots.</p> <p>Operating System: All<br/> Platform: All</p> YANGTOOLS-482

Thank you very much.</p> <p> Martin</p> <p>Hi Mina, do not see why this is bug, time you see is spent actually serializing out data you requested - serialization of data actually takes only 1.7 % of time, so I do not see this as a problem. </p> <p>What is your expected behaviour, what are you expecting to change? Otherwise I will close this as Resolved-Invalid - since "inventory" is not YANGTools issue<br/> and bug description + attachments does not provide enough context to determine issue.</p> <p>The reason it is logged against YangTools is the significant increase in the invocation calls when yangtools are called!</p> <p>Why one invocation call should go beyond 1800 calls?</p> <p>Call to process / write / read for each XML / JSON element - there were around 200 elements in one list (probably flow list).</p> <p>So given that you were serializing / deserializing 200 flows, 200 invocations makes sense. Closing it as INVALID.</p> <p>This call process data based on schema - each field in JSON, given that you had 200 flows, with 9 leaves gives you 1800 operations. Since this is generic framework invocation count makes sense.</p> <p>If you profiled any XML / JSON serialization framework you would observe same pattern (small methods invoked for each field for each object).</p> Development External issue ID 4074 External issue URL Rank 0|i027hz:
