This Jira is to improve the overall performance of the EnhancedExactUnmarshal. You won't be able to reproduce the slow times anymore as a change was push to cache the result of the call to EnhancedExactUnmarshal and pull from that cache rather than unmarshal it every time. I can try to find the PR where those changes were made so you can see the caching mechanism.
 
I assume we would still want to improve the performance of this call as the cache is a workaround to the poor performance, but I'll defer to Matt on that question.

Subject: [EXTERNAL] [Hyperledger Fabric] [FAB-17598] Improve the efficiency of viperutil.EnhancedExactUnmarshal
Date: Wed, May 20, 2020 10:06 AM
 
Hello:
 
New comer to HL fabric, starting out by building, running and understanding the unit and integration tests. Picked the help-wanted JIRA issue below
 
 
Just took a sample set of the following tests peer.TestCreateChannel, genesisconfig.TestLoadProfile.func1. Tried to reproduce as shown below, it seems to be completing in milliseconds as opposed ~5seconds below. I tried doing "make unit-test" and "make integration-test" but unable to get the issue.
 
Possibly am missing something in my repro steps, any pointers on steps to repro would be helpful.
 
Thanks,
Nicholas.
 
 
 
(Tried using the recommended method of TEST_PKGS="github.com/hyperledger/fabric/core/ledger/peer" make unit-test, but the run was cached inspite of giving -count=1 in GO_TAGS, then resorted to the method below)

nb@~/Documents/github.com/nbasker/fabric$ go test -v github.com/hyperledger/fabric/core/peer | grep TestCreateChannel
