[support] Improving performance

[Jamie Holly]

The high performance group on drupal.org is really good:

https://groups.drupal.org/high-performance

The most common recipe is APC for opcode caching, memcache for object 
caching and Drupal's database to cache the form table.

APC also offers object/user caching, but you do have to spend sometime 
getting it tuned right so the memory does fragment. In one high 
performance site I manage I use the same recipe as above, but I use APC 
to handle page caching.

Of course all this varies greatly by site. Some sites are mostly 
anonymous users, meaning page caching is the key, while others have a 
heavy logged-in user base, so object caching becomes the big factor.

Also depending on how the site is built, there's other cache modules out 
there that really help, like views cache, authcache and panels cache.

Currently running Memcache and APC -  the PHP accelerator, but not sure whether there would be anything to gain by implementing Drupals caching as well. Wouldn't mind finding some way of measuring the effects of the various performance enhancements. Are there any downsides to Memcache and APC?
