Query performance for non-depot data

The performance penalty for a depot miss varies according to I/O speed of communal storage, concurrency load on communal storage and network bandwidth.
On AWS, for the simplest of queries against a single table, we have seen an approximate difference of 10X (the query takes 10 times as long to run).
On Pure Storage FlashBlade with a dedicated network for inter-node communication, for the simplest of queries we have seen a 30% performance impact (the query takes 30% longer to run). While this 30% performance penalty seems low, it quickly multiplies when multiple joins are involved.
Whatever platform you choose, we strongly recommend running a POC to assess performance differences against your individual schema, queries to inform your hardware configuration.
