CrossOver Chromium vs. Firefox 3 – Javascript performance results

An interesting thing happened on my way to the web today. While reading through my rss feeds, I came across a story about CrossOver doing a Proof of Concept port of Chromium to CX. Interesting since the mighty “g” can’t seem to get it together for Linux. I’ve already downloaded and played with Chromium at work on my XP box and was impressed with the speed. It seemed much snappier than FF3.

So being an overly curious bugger, I downloaded the deb pkg for Ubuntu32. Yeah, it looks pretty rough — but what the hey, it’s a PoC right? So, I thought maybe a little speed test is called for, so I googled “javascript test” and my cloud brain returned, “Sunspider JavaScript Benchmark“.

So I fired it up in the cxChromium port and then it the standard FF3 on Ubuntu. Here is what I saw for cxChromium. I then swing over with FF3 and get these results.   Javascript in FF3 is 2.44x slower than cxChromium.  Man oh Man, is the v8 javascript engine a hummer.

To enable xdmcp in the terminal server client for Ubuntu (edgy). By default the
terminal server client program has xdmcp disabled. To fix this just

installing pysqlite in a workingenv on unbuntu 6.10

I tried setting up a workingenv for playing with SQLAlchemy today but I ran into a number of problems. First, since I had installed pysqlite2 via Synaptix, easy_install was not finding the package. So I had to uninstall the pysqlite2 that I had installed with Synaptix and then install with easy_setup.

However, there is a bug for pysqlite on cheeseshop and no download is listed. So after inquiring on the TG mailing list, I tried:
easy_install -f http://initd.org/pub/software/pysqlite/releases/2.3/2.3.2/ pysqlite

but that failed because it couldn’t find the sqlite headers.
In file included from src/module.c:24:
src/connection.h:33:21: error: sqlite3.h: No such file or directory
...
error: Setup script exited with error: command 'gcc' failed with exit status 1

So I installed the libsqlite3-dev package via Synaptix — and finally all was right with the world.

I couldn’t get pysqlite to install fully into the workingenv, so I had to install it on the base system and then when I issued the
easy_install -f http://initd.org/pub/software/pysqlite/releases/2.3/2.3.2/ pysqlite
in the workingenv a proper entry was made pointing back to the package in site-packages
Adding pysqlite 2.3.2 to easy-install.pth file
Using /usr/lib/python2.4/site-packages/pysqlite-2.3.2-py2.4-linux-i686.egg
