The effort underway to stabilize the website and make room for more growth continues. Several of the bloggers have noticed issues, particularly with commenting, and those have been fixed for the most part. On the upside, we have made vast improvements to overall site performance. Between WP Super Cache and APC, we’ve seen a huge drop in CPU and RAM utilization as well as the number of connections to MySQL.
What this means for most users: Retrieving a page from the server is faster than before.
Even though the improvements made thus far have been significant, there are even more optimizations that can and will likely be made over the coming weeks and months.
On an unrelated side note, bloggers can now comment through the administration interface without having to approve their own comments.
