Yes they absolutely can.
Same-core context switching costs a few microseconds.
Going across core complexes can cost tens to hundreds of microseconds.
These figures are several orders of magnitude (5-6) slower than L1 access on the same thread.
- crazygringo 2y agoHundreds of microseconds? L1 access? I don't have the faintest idea of what you're talking about. Communication between processes is negligible compared to all of the sequential disk/SSD accesses and processing required for executing queries. The database isn't stored in L1 and communication isn't taking hundreds of microseconds. I don't know where you're getting your information. The fact that SQLite is in-process is primarily about simplicity and convenience, not performance. Performance can even be worse, e.g. due to the lack of a query cache.
