Yes strfry is the fastest nostr relay atm. All others fall over and die.
Discussion
When others fall over, what’s the common problem?
Writes or reads/filter requests?
My assumption is reads since different filters by the various clients need to be handled?
CPU bound. Other DBs just aren’t fast enough even when indexes are optimized. The sqlite relay failed the fastest. Snort social runs a postgres one and it eventually died. Strfry is so fast it almost feels like a cache.
