Estimated effort

TBD

Out of scope

• Implementation of the actual fix. Currently, we want to focus on identifying where things are congested instead of coming up with a solution and applying the fix

TLDR: the fixes can give ~2x speed up but the implementation is more challenging than expected. We need to implement caching properly and estimate impact of reducing gas costs. More details at https://near.zulipchat.com/#narrow/stream/295306-contract-runtime/topic/bottleneck.20on.20compile_and_load/near/427502581 and above.

I would ask @tayfunelmas and/or someone from @near/contract-runtime to track this further.
