Browser javascript-crunching speed comparison

news No Comments »

Test done with Dronaeo website (a collection of some JS benchmark script done by Mozilla foundation) on a 2.4GHz Macbook w/ 4GB of RAM.

Windows Vista SP1 (virtualized in Parallels)

Google Chrome pwns all… it’s the 1st column, wrongly reported by dromaeo test as “Safari/525.13“. Firefox 3.01 is four time slower, and Opera 9.51 and Safari 3.2.1 for Windows (reported as “Safari/525.21“) are closer. And oh, IE simply crashed running the page ;(

Mac OS X 10.5.3 Leopard

Firefox 3.0.1 wins, but Safari 3.2 made very similar points… Opera is a bit slower than in the windows counterpart… (Good ‘ol) SeaMonkey and Shiira (reported as “Firefox/2.0.0.16″) are four times slower…

Linux Kubuntu64-current:

Galeon (linux only) is the fastest browser after Chrome, but Firefox 3.0.1 is very near. Konqueror 4.1.1 and Opera 9.52 make decent figures, SeaMonker as usual is the last ;D

Now some inter-OS speed comparison:

Firefox 3.0.1: http://dromaeo.com/?id=28106,28286,28540
measured exactly the same speed on ALL os!

Opera 9.52: http://dromaeo.com/?id=28169,29286,28303
is a lot faster on Windows than Linux or OS X.

Seamonkey 1.1.11: http://dromaeo.com/?id=27933,28439,29213
is slightly faster on Linux than Windows or OS X.

EDIT: Google Chrome vs all memory usage screenshot here.

7200rpm: is it worth it?

news No Comments »

When I bought the macbook I immediately replaced the stock 160GB, 5400rpm hard disk with the faster 7200rpm in production nowadays: her majesty Hitachi 7k200 (HTS722020K9SA00).

Being this HDD quite expensive (due to the shortage in production) how much it improves seek/read time? I can confirm that power consumption and noise are the same as the stock unit, and that is wise to buy the 100 or 200GB models with an higher storage density per disk face in comparisono of the 160 GB unit.

Here there are some benchmark between a 200GB 7200rpm Hitachi 7k200 running a 3,1 macbook (2.2GHz Merom based, 4GB ram) and the stock 160GB 5400rpm Fujitsu on a 4,1 macbook (2.4GHz Penryn, 4GB ram). So sorry but no HFS+ bench, I can’t find any decent benchmark app for OS X: Xbench is extremely old, and Geekbench 64 told me absolutely random crap marks on the new Penryn, reporting a numerical result more or less the half in comparison of the “old” Merom one!?!
