xphlo
October 31st, 2008, 10:18 PM
I used 8.04 i386 alternate cd and did a command line install to an 8GB usb. From grub on the MBR, I use ´configfile (hd0,4) /boot/grub/menu.lst' to boot this particular installation (which also uses grub). I have installed xorg, openbox, and firefox3.0, and a few various packages.
I write because I am getting some annoying lag. Startup is always a little slow, but most programs are very quick after their first call.
But certain programs (notably firefox) never improve.
If I stay in the same window,tab,and webpage for a while, I will get good performance with flash apps, javascript, and standard html. But anytime a new page is loaded in any way, firefox just freezes up. I cant change focus to a text field (cant type either), links wont work, scrolling, screen doesn´t repaint; the same ol. It will progressively get better over 20-30 seconds, but each new page and it starts over.
I also notice many disk WRITES while a lot of this is happening. This may be ill founded, but the disk writes and bad performance seem to go hand in hand.
I understand a usb isn´t lightning fast, but after a while, firefox should be in ram. Why am I waiting for disk writes?
Is my root filesystem poorly configured? Do I need to add filesystems (cache,tmp,???)?
Ill open several firefox instances, and when they start to slow down, ill post some details below.
