CHI::Benchmarks(3pm)

💖 CHI::Benchmarks 💖

okay bestie, this is CHI::Benchmarks — part of the User Contributed Perl Documentation crew, and it's literally just the receipts for how fast (or not) every CHI driver actually is. no cap.

✨ VERSION ✨

this is version 0.61 🎀

---

🌸 DESCRIPTION 🌸

so these benchmarks? they were made by running this exact thing:

etc/bench/bench.pl -d . -t 10 -x

and that was for CHI 0.42, on OS X v10.6.6, a 2.2 GHz Intel Core 2 Duo, running Perl 5.12.2. vintage, i know. 👑

for every single cache, bench.pl does repeated gets and sets of a data structure for at least 10 seconds, and it measures the wallclock time per operation. simple as that.

bestie. listen. these numbers are a rough guideline ONLY. like, do not take them as gospel, i'm begging. actual results will vary widely depending on your system, your get/set pattern, the actual values being set, whether your memcached/mysql is properly tuned, etc. etc. etc. for the best results, run the benchmark script (it's available in this distribution 💅) on your own system. fr fr.

and here's the iconic little chart, exactly as it is:

Cache                Get time Set time Description
cache_ref            0.009ms  0.008ms  Cache::Ref (CART)
chi_memory_raw       0.019ms  0.036ms  CHI::Driver::MemoryRaw
cache_fastmmap       0.022ms  0.040ms  Cache::FastMmap
chi_memory           0.042ms  0.066ms  CHI::Driver::Memory
chi_berkeleydb       0.052ms  0.073ms  CHI::Driver::BerkeleyDB
chi_fastmmap         0.057ms  0.087ms  CHI::Driver::FastMmap
cache_cache_memory   0.065ms  0.070ms  Cache::MemoryCache
cache_memcached_fast 0.097ms  0.131ms  Cache::Memcached::Fast
chi_dbi_sqlite       0.112ms  1.659ms  CHI::Driver::DBI (sqlite)
cache_memcached_lib  0.118ms  0.156ms  Cache::Memcached::libmemcached
chi_file             0.118ms  1.138ms  CHI::Driver::File
chi_memcached_fast   0.138ms  0.178ms  CHI::Driver::Memcached::Fast
chi_memcached_lib    0.151ms  0.202ms  CHI::Driver::Memcached::libmemcached
chi_dbi_mysql        0.236ms  0.273ms  CHI::Driver::DBI (mysql)
cache_memcached_std  0.238ms  0.180ms  Cache::Memcached
chi_memcached_std    0.279ms  0.235ms  CHI::Driver::Memcached
cache_cache_file     0.481ms  1.391ms  Cache::FileCache

look at cache_ref at 0.009ms get time just casually being the main character 😭 and then cache_cache_file at 0.481ms / 1.391ms sitting at the bottom of the leaderboard. it's giving ✨range✨.
