So, why is IndexedDB so slow on Chrome? Obviously LevelDB doesn't need 10ms for a point read. If it did, nobody would use it for anything. 10ms is a hell of a long time. Is it spawning a process to perform the read or ??
I was profiling on an older computer. On my newer one, summing 100 items takes ~8ms (use the raw idb mode). When I said "simple operations" I meant simple queries that you'd expect apps to write, not just 1 single read/write. It is a little faster for each read/write, but there seems to be a bottom floor. Even if reading an item itself is fast, opening a transaction is slow. So any query, even if it only reads one item, is going to suffer the perf hit of opening a transaction.
It's only twice as fast as Firefox, so overall IDB is still super slow when compared to running the same queries with native SQLite. We're talking summing 100 items taking ~.01ms or less. I have no idea why it's so slow.
