Nice Demo of Benchmarking and Optimizing a WordPress Blog

Optimize WordPress for speed

Here are the results from my current (old) system for comparison:

Benchmarking thebside.ca (be patient).....done

Specs of the old machine:


Athlon XP 2100+, 756 MB RAM

hdparm -tT /dev/sda1

/dev/sda1:
Timing cached reads:   336 MB in  2.00 seconds = 167.97 MB/sec
Timing buffered disk reads:  192 MB in  3.03 seconds =  63.40 MB/sec

Now below are the numbers for my new hardware, though they may deteriorate as I add additional services.

Benchmarking localhost (be patient).....done

Server Software: Apache/2.2.11
Server Hostname: localhost

95% 1666
98% 1734

100% 1781 (longest request)

And the new server’s specs?

AMD Athlon Dual Core 5050e, 4GB RAM

hdparm -tT /dev/sda

/dev/sda:
Timing cached reads: 1292 MB in 2.00 seconds = 646.06 MB/sec
Timing buffered disk reads: 252 MB in 3.00 seconds = 83.94 MB/sec

So things are looking good!
