Expand description

Global cache statistics for LoadedPrograms.

Fields§

§hits: AtomicU64

a program was already in the cache

§misses: AtomicU64

a program was not found and loaded instead

§evictions: HashMap<Pubkey, u64>

a compiled executable was unloaded

§reloads: AtomicU64

an unloaded program was loaded again (opposite of eviction)

§insertions: AtomicU64

a program was loaded or un/re/deployed

§lost_insertions: AtomicU64

a program was loaded but can not be extracted on its own fork anymore

§replacements: AtomicU64

a program which was already in the cache was reloaded by mistake

§one_hit_wonders: AtomicU64

a program was only used once before being unloaded

§prunes_orphan: AtomicU64

a program became unreachable in the fork graph because of rerooting

§prunes_environment: AtomicU64

a program got pruned because it was not recompiled for the next epoch

§empty_entries: AtomicU64

the [SecondLevel] was empty because all slot versions got pruned
