More than 30s to build a block on Kusama

[Tbaut]

Hello there,

I'm running Chopsticks in Github CI, forking Kusama with the same example config that you have. Just with a couple more funded accounts.

However, it very often takes more than 30s to create a block in CI, although I would expect it to take only a couple seconds. E.g here it took 34s

 [16:20:51.742] INFO (block-builder/1744): Try building block #20,487,321

    ]

It takes locally ~20s

I've tried to comment out the line below ParaDisputes without changes https://github.com/AcalaNetwork/chopsticks/blob/master/configs/kusama.yml#L54

any hint?

make sure to use an endpoint without rate limit or at least with high burst. chopsticks can build block within a second if has the storage but it depend on endpoint to pull the data, so that contributes to the delay

Thanks a lot for the hint Ermal, I found an RPC that indeed takes a couple seconds locally, and 10s in the CI, that's already a great improvement.
