I recently temporarily did away with cookie-processing to save some horsepower, but it's going back in when the new server arrives. I'm hoping to get lease approval from Dell today to get it on its way.
Still haven't gotten the load-balancer ordered, though. Took this long to find out that the few that Dell has cost more than double what I'd pay for the Coyote Point E350 through CDW.
