fast-cache

A very fast kyoto cabinet powered memcache interface http proxy caching server.

Very rough done benchmark so far, just running against a local wsgi app with 5 gunicorn workers returning {} only.

import random
import time

import memcache

mc = memcache.Client(["127.0.0.1:7000"])
# hack to make sure we force the connection before the first call
for server in mc.servers:
    server.connect()

elapsed = 0
total = 0
numbers = range(5000)
for _ in range(100000):
    start = time.time()
    result = mc.get("test:%s" % random.choice(numbers))
    end = time.time()
    if result is None:
        break
    elapsed += end - start
    total += 1

print "Total: %s" % total
print "Total Elapsed: %s" % elapsed
print "Average: %s" % (elapsed / total)
print "Req/sec: %s" % (total / elapsed)
