memcached ssslllooowww on Mac OS X

The purpose of memcached is .. to be fast .. . Unfortunately the default port (Darwinports) is really slow (slow as in 3 seconds of doing nothing on a 1.8GHz PowerPC G5), and somebody figured out a fix.

Now here are few notes on how to recompile it (quick and dirty):

• find the source /opt/local/var/db/dports/distfiles/memcached/memcached-1.1.11.tar.gz . Unpack it (ex: on Desktop)
  

• as suggested in fix., edit the memcached.c file, adding #undef TCP_NOPSH on line 105
  
• find the location of libevent (which came as part of port install)
  
• in the folder with patched memcached run
• ./configure --with-libevent=/opt/local/var/db/dports/software/libevent/1.1a_0/opt/local/
• make
• take a look at the original permissions
  
• copy new file into it's original location by: sudo mv memcached /opt/local/bin/memcached
• restore original permissions : sudo chown root:admin /opt/local/bin/memcached

Now start memcached frm command line (memcached -vv for verbose logging), and test as it says in the README (from python):

import memcache
mc = memcache.Client(['127.0.0.1:11211'], debug=0)

mc.set("some_key", "Some value")
value = mc.get("some_key")

Now it will not wait 3 seconds
