A young computer scientist and two colleagues show that searches within data structures called hash tables can be much faster than previously deemed possible.
I’ve only used java but java hash tables are stupid fast in my experience, like everything else in my crap programs was 1000 times slower than the hash table access or storage.
Just reading the title, it’s talking about searching hash tables, which wasn’t something I was specifically doing.
Using bencode over json would probably speed up the web more. Not to mention good ole ASN.1 (well, at least some binary schemes for ASN.1). The web is completely cooked when it comes to efficiency.
JSON libraries are stupidly well optimized. There are binary encoding schemes that are faster and more compact, but its hard to beat JSON for text-based.
I don’t think the speed of hash tables is a problem in most applications except benchmarks.
Hash tables are often used behind the scenes. dicts and sets in python both utilize hash tables internally, for example.

anything that deserializes arbitrary json will put it into a hash table, right? it would definitely speed up the web.
Depends on the implementation, but most will, yes. There are other forms of associative arrays, like trie or binary tree, but hash is the most common.

the biggest speedup would probably come from using proper schemas that can be efficiently parsed. but we’ve made our bed out of ad-hoc protocols.
And yet all that pales in comparison to using react (or whatever framework) over vanilla js. Enter McMaster-Carr.
yupyup, just send HTML over the wire. it’s fine.
