PR description

Introduce "undoable" journoled collections: set, map, table, and list
Move values that are the same or shared across the transaction to
TxValues record
Move warm and cold storage to undoable sets and tables.
Move transient storage to undoable table.
Move address hashing inside of address with a memoized field.
lazy create EOF return stack

Fixed Issue(s)

A series of collections that can be rolled back to a prior state. Signed-off-by: Danno Ferrin <danno.ferrin@swirldslabs.com>

I thought about documentation and added the doc-change-required label to this PR if updates are required.
I thought about the changelog and included a changelog update if required.
If my PR includes database changes (e.g. KeyValueSegmentIdentifier) I have thought about compatibility and performed forwards and backwards compatibility tests

we don't want to add a limit for this cache ?

What limit would you suggest?

I would say a maximum size. Maybe we should see how much on average we load hash by block and got a number. But with a cache without max seems dangerous to me . Or else there is a default limit?

is it still need to have memoize in this case ?

I applied it to all cases where we saw Hash.hsah(addres)) to be consistant.

8%->80% performance improvement in the call/delegate call operation, respecitivly.

When I look to the CPU profiling in case of Call operation, I see roughly the same percentage in samples pre and post this PR, around 63%. Is it the right screenshot ? Am I missing something ?

ahamlat · 2023-06-06T13:10:45Z

I'm still reviewing the PR, meanwhile I installed this PR on a Mainnet node to test the performance improvement compared to main branch

Assuming sampling is at the same fixed interval, the CALL samples had 3190 pre and 2943, so pre had 8.39% more samples. for DELEGATECALL the change was more dramantic at 4152/2249, so pre had 84.61% more samples. I'll get my CartEVM results tomorrow.

Total time decreased, not so much share of computation.

I also don't have a good "tower" call benchmark (where we do 1000 deep callstacks). I'll dig into reference tests for a good example. That is where I expect the most payback for undo collections.

What surprised me is just how much time is spent in the call frame init as opposed to other work steps.

shemnon · 2023-06-07T00:31:16Z

I also want at a day of fuzzing before it gets committed.

Full day of fuzzing.

Got the idea, I'm used to profile on the same period, and in you case, the profiling was done during the test execution time.

I also don't have a good "tower" call benchmark (where we do 1000 deep callstacks). I'll dig into reference tests for a good example. That is where I expect the most payback for undo collections.

Please let me know if I can do the tests for you, I can launch some AWS instances and do whatever you want in terms of tests, I will just need some guidelines.

What surprised me is just how much time is spent in the call frame init as opposed to other work steps.

On Mainnet (without this PR), getCode takes most of the time when calculating the keccack hash of the code.

shemnon · 2023-06-07T15:58:06Z

Tower call results are unimpressive, so given the breadth of the change I'm going to shelve it as not worth the risk.
Only 10% on calls...

Berlin is where access lists were introduced and is where the showdown is.

If actual on-chain gas limits are used (due to 63/64) stats are much better, but only a 70 high tower gets built - the reference test case Delegatecall1024OOG.json shows this

Performance numbers

"all in" performance is a small drop within statistical noise. data
performacne of CALL, DELEGATECALL, and STATICCALL improve 20%-26% data
Selfdestruct takes a nearly 80% hit, but that is from an absurd 5.9 GigaGas/sec to 1.3 GigaGas/sec data

Call ops are still the worst performers, so raising the floor is worth the hit to a lesser used top performing operation.
