I've been using Magento 1.9.X with Redis and have gotten:
working, however I have not gotten lzf working. In the local.xml file, I've typed "lzf" for the compression level but it doesn't seem to be working after restarting redis. Has anyone gotten this working?
Credis (bundled in Cm_Cache_Backend_Redis) will only enable lzf if you have the lzf_compress function available, what does:
<?php echo function_exists('lzf_compress') ? 'yay' : 'nay'; ?>
report if you pop it into a .php file? If it's 'nay' you'll need to grab it from PECL first,
