Problem: Pruned node syncs really slow and uses more space

# From the doc
Pruned node (setting pruning=everything) 
Storage: ~25G* 
RAM: 4 GB (LevelDB) or 64G RAM (RocksDB)*** 
CPU: 4-core

# config.toml
db_backend = "goleveldb"

# app.toml
pruning="everything"

# mem
free -h

I have been using cronosd (v0.6.10) to syncs from 1 to 2,693,800 for over one week. It seems too slow for syncing. Is it normal for a Pruned node? It has used 468G disk space which is more than 25G. Am I doing something wrong? Thx.

how large is the application.db, because pruning setting only affect that one, the storage requirement in doc maybe out of date.

101G ./application.db

not much we can do in current version, you can try scale up the machine, especially increase amount of ram. In future version we'll have some dramatic improvement at db level.
