Memcache client very slow?

Rails
1

Case 1: Ruby + Ruby-MemCache + onboard memcache (the cache) - 10.5
seconds

Case 2: Python + REMOTE memcache (the same cache as the other) -
0.2seconds

Please please tell me I’m doing something very wrong… - and examples
of
the right way would be great.

here’s my code:

require ‘memcache’

mem = MemCache.new ‘10.253.9.158’
#mem = MemCache.new ‘127.0.0.1’

t1=Time.new
list1 = mem[‘red’]
list2 = mem[‘car’]
t2=Time.new
puts (t2.to_f - t1.to_f).to_s

list3 = list1.split(’:’) & list2.split(’:’)
t3 = Time.new
puts (t3.to_f - t2.to_f).to_s
puts list3
t4 = Time.new
puts (t4.to_f - t3.to_f).to_s

Try memcache-client instead…

It’s supposed to be a lot faster…

Also, if this is on a mac and you’re using memcache 1.2.0 recompile it
and
tweak the following:

edit memcached.h and add ‘#undef NO_TCPPUSH’ to the top

Can’t remember where exactly I read that, but it makes a huge
difference.

Well, the python-memcache was 50x faster, got it down to only 4x faster
w/
memcache-client as suggested.

Two other things I’ve noticed:

  1. Python is much more stable - I very rarely get any kind of
    corruption
    or unexpected behavior - I’ve had to start over 5 times w/ ruby’s
    memcache.

  2. Ruby seems to care much more about marshaling, etc. Python seems
    quite happy to let you leave things as strings and do your own parsing.

Am I insane to consider trying to figure out how to use a python library
in
ruby? Is there such a thing? Or perhaps I should use a ReST API hosted
by
python, available from ruby - http://localhost:11212/search?key=‘red’
(and
in fact I’m only going to be GETing from ruby - doing all the bulk cache
loading on the python side thanks very much).

Any other suggestions?
