If you are planning architecture for a very large online service or website, it’s recommended you avoid control panel software from the very beginning. If you intend to run a web-based service, why do you need running email, DNS and many other services on the same server? How about scalability and performance tuning when load and visitors increase?
The fewer services you run on the server, the harder it is to exploit, and the more system resources will be available for website hosting and script processing. Most web hosting control panels run a lot of software – altering the default… Read the rest of this entry »

We performed Bind 9.4.2 benchmarking using our Gigabit network and Linux server nodes. The following performance was easily recorded using one zone and doing IN A requests using queryperf tool.

Lately, we have been testing our server environment and setting up our Linux powered lab where all servers are connected to 1Gbps managed switches.
One of the first tests we had was testing Ethernet cables – CAT 5e and CAT 6 category cables. CAT 6 is the standard for Gigabit Ethernet and backward compatible with CAT 5 and CAT 5e. CAT 6 provides performance of up to 250 Mhz.
In our tests we will review data transfers between two servers each connected to 1Gbps switch. Our maximum data throughput for these boxes are at around 350Mbps due to network card… Read the rest of this entry »
