Memcache 1.7 Released

Drupal Scaling

I am very happy to announce the release of Memcache 1.7 for Drupal.  The most notable improvement being the addition of pluggable sessions for memcache.  Memcache is an instrumental module for scaling Drupal sites and we now have a release that is more stable than ever.

From danga.com - "memcached is a high-performance, distributed
memory object caching system, generic in nature, but intended for use
in speeding up dynamic web applications by alleviating database load.
"

Drupal sites which often see very high database load as they grow in popularity, can alleviate some of this load by installing memcached and the Drupal memcache module.  With session caching in memory you can see a very substantial speed up in page load time and decrease in the amount of resources consumed on the server.  This allows for greater scalability and better performance of your existing infrastructure.  In testing we have seen authenticated user page load times get reduced from 4-5 seconds down to 200ms or less by using Memcache with the Advanced Cache module.

Thanks to Russell Uman , Robert Douglass and Thomas Achtemichuk  for their hard work in debugging and testing.

Achieve Internet is excited to announce the recent launch of a new Digital Health Library created for our long-standing client Scripps Translational Science Institute.  
The importance of monitoring your server access logs We recently had a client come to us with random performance problems on their site.  The site is a low traffic brochure site on a shared hosting account.  Most of the time the site performs reasonably well.  However, there are mysterious times where the site slows down to a crawl. This reached a critical point Friday afternoon and their hosting provider shut down the site for using too many server resources.
