capacity update

Just to keep you all in the loop -- the servers have been really busy lately! [personal profile] alierak, one of our sysadmins, has been working on things and found an issue with our load balancer. He fixed that, and that has resolved a number of issues people have had connecting to Dreamwidth during periods of peak load.

(For the technical, the issue was that our connection tracking table in the kernel was set to the default 64k, and we've started peaking past that. He raised the limits.)

We have also submitted an order for two more web servers. This will make things faster by just giving us more horsepower to work with. The rest of the system (databases, memcache, network, etc) isn't anywhere near capacity, but we're running low on CPU on our web servers.

We also have some of our developers working on optimizations for entries that have many comments. That work is in progress and we will continue to iterate to make things faster.

If you have any questions, let me know! I'll do my best to answer them quickly and accurately. :)
