So fast growth of storage usage after upgrading to 0.50.x, IAVLv1

[TxCorpi0x]

Description

The observation and tracking of storage usage on blockchain after upgrading to SDK v0.50.x and iavl v1.2.4 show a tremendous speed growth.

Storage usage, especially application.db (for seed/validator node) and blockstore.db (for full node), comparison shows:

1. Seed Node 2.5 GB per day
2. Full Node 8.5GB per day

according to benchmarks here it seems IAVLv1 is storage consuming.

Is there any suggestion or a similar experience?

iavl v1 should be more efficient than iavl v0, but when you upgrade iavl v0 to v1, there's a phase that v0/v1 co-exists, not sure if the mix phase makes things worse.

So this coexist phase continues as long as new transactions hit the old state, i believe. in our situation, the upgrade happened about 2 months ago. is it going to be a last-long task (coexist)?
Whether fast sync can fix this issue?
