72c59f0b68 if there's only one item search result, redirect to it 2013-07-09 19:54:22 -07:00
5e60795f31 Oops, delegate Item::Proxy#to_param to the item, or we get bad links. 2013-06-27 10:47:02 -07:00
5b9394ce82 oops - don't cache as_json's owned/wanted, but instead have the proxy override 2013-06-27 00:10:55 -07:00
9e3cac82ec use proxies for item html, too
Some lame benchmarking on my box, dev, cache classes, many items:

No proxies:
    Fresh JSON:  175,  90,  90,  93,  82, 88, 158, 150, 85, 167 = 117.8
    Cached JSON: (none)
    Fresh HTML:  371, 327, 355, 328, 322, 346 = 341.5
    Cached HTML: 173, 123, 175, 187, 171, 179 = 168

Proxies:
    Fresh JSON:  175, 183, 269, 219, 195, 178 = 203.17
    Cached JSON:  88,  70,  89, 162,  80,  77 = 94.3
    Fresh HTML:  494, 381, 350, 334, 451, 372 = 397
    Cached HTML: 176, 170, 104, 101, 111, 116 = 129.7

So, overhead is significant, but the gains when cached (and that should be
all the time, since we currently have 0 evictions) are definitely worth
it. Worth pushing, and probably putting some future effort into reducing
overhead.

On production (again, lame), items#index was consistently averaging
73-74ms when super healthy, and 82ms when pets#index was being louder
than usual. For reference is all. This will probably perform
significantly worse at first (in JSON, anyway, since HTML is already
mostly cached), so it might be worth briefly warming the cache after
pushing.

e42de795dd Use item proxies for JSON caching
That is, once we get our list of IDs from the search engine, only
fetch records whose JSON we don't already have cached.

It's simpler here to use as_json, but it'd probably be even faster
if I figure out how to serve a plain JSON string from a Rails
controller. In the meantime, requests of entirely cached items
are coming in at about 85ms on average on my box (dev, cache
classes, many items), about 10ms better than the last
iteration.
