Slow Transaction Processing

[YasirAzeem]

I set up 4 iroha nodes on GCP Compute Engine Instances.

Instances details are as follows:

1vCPU and 3.75 GB of RAM
Ubuntu 16.0 LTS

I used latest docker image for Iroha and ran irohad with sample config.docker with MST enabled

Here are the logs for irohad with verbosity 3
log.txt

Each transaction takes around 40-50 seconds to commit. I am using Python SDK to push transactions to network and to check the status of the transaction.

Here are the status logs sent to one peer and tx status from that same peer. As it can be seen, its taking too much time.

Hello @YasirAzeem, please check that you did not send a hundred of transactions with max_proposal_size set to ten. If so, try to increase max_proposal_size and check.

Please reply if the issue has been solved or it is still here.

[YasirAzeem]

No I am just sending one transaction not 100s and my max proposal is set to 5 only

@igor-egorov Issue is still there even with the new merge into master/latest branch. Still slow processing. Same logs.

@YasirAzeem which client library do you use?

[neewy]

Now I see that you are using python SDK

[YasirAzeem]

Yes Python SDK present in example the one with prepare.sh

[neewy]

@YasirAzeem sorry, but we are abandoning the support of code-generated libs. You can find a new library here: hyperledger-iroha/iroha#2028

Here is the video with a screencast on how to use this new library: https://www.youtube.com/watch?v=PN7WoLReDs4&frags=pl%2Cwn
This new library will be available soon at https://github.com/hyperledger/iroha-python/tree/develop repo

[YasirAzeem]

I don't think its the problem of the library as you can see from the logs file I sent, other nodes don't even have the transaction until a few seconds have elapsed. They show status as if there hasn't received it at all but after a few seconds all nodes accept it. Its all there is on Irohad logs as well. Those are also attached.

[YasirAzeem]

@neewy Are you sure its only old Python SDK issue? It doesn't seem like that.

@YasirAzeem Are you still having this problem with rc4?
