WIP feat: reduce number of online vats#158
Conversation
|
I suspect 5 is a much too aggressive number, and would result in a lot of paging in and out of vats, which is expensive. What is the problem being solved? What does "load" mean in this case? Unused but loaded vats would at most consume memory, is that the concern? |

I don't know whether this PR is a good idea, but if it goes forward I would suggest setting the option instead of changing the default.
I.e. adding a warehousePolicy to the runtimeOptions param here: https://github.com/Agoric/agoric-sdk/blob/50f94936e038d6b8872dfde77b5f54811f339ccd/packages/cosmic-swingset/src/launch-chain.js#L221-L233

You are right. I wanted to experiment without making a change in agoric-sdk to verify that it works, and then make the change in agoric-sdk so that we don't need a patch here.

Reducing maxVatsOnline to only 5 online vats to reduce the load on the system that is running this container.
Testing:
Tested locally to see if this SwingSet change works without a3p. Now, with PR, trying to build an image in the CI to test.
