Hi,<br>
<br>
In order to have more feedbacks before deciding to switch to Firefox,<br>
or to keep Chromium by default, I would like to ask you some<br>
testimonies and any feedbacks about the use of the 2 browsers. We need<br>
to evaluate the use of the 2 browsers *on old and not-so-fast<br>
hardware*. It's important because our main targets are this type of<br>
hardware. I know people are using Lubuntu on high specs hardware (like<br>
me), but this is not our main goal to optimize the system for this<br>
type of people.<br>
<br>
One tip if you want to compare memory usage between the 2 browsers :<br>
go to the address chrome://memory under chromium. That should not be<br>
the only source of information, but it can help in your evaluation.<br>
<br>
So, if you have feedback on using both browsers, please bring it to us<br>
:-) But please, keep the discussion on this topic (feedback on low<br>
spec hardware).<br>
<br>
Thanks in advance :-)<br>
<br>
Regards,<br>
Julien Lavergne<br>

I did some test with my old dsektop PC with the following spec:<br>
CPU: Intel Pentium 4 3GHz (single core) with HT turned on.<br>
RAM: 768 MB<br>
OS: ArchLinux (no ubuntu on this machine)<br>
I tested Firefox, Chromium, Midori, Arora, and Qupzilla.<br>
None of them work after I open more than 3-4 tabs because they use up my RAM.<br>
Almost all of them are frozen after I open facebook + yahoo.<br>
The command "free" showed that simply after opening 3-4 pages I run<br>
out of my RAM.<br>
My swap is being used quite frequently. Hence the freeze.<br>
<br>
However, after I did the following, things changed a lot.<br>
1. Use CK-patched kernel (BFS scheduler) => only mild improvement<br>
2. Edit /etc/sysctl.conf to set "swappiness" to 10 instead of the<br>
default 60 => use swap less frequently inititally<br>
3. Install zram module => Greatly improve overall performance!!!<br>
<br>
After the preceding changes, Midori becomes the fastest. Things are<br>
still smooth after I open several tabs.<br>
Switching among tabs are fastest with Midori. Then Firefox is the<br>
second smooth browser.<br>
Arora and Qupzilla are still slower than Midori.<br>
<br>
I dropped Midori long time ago because it crashes constantly.<br>
However it has improved a lot in these years, too, just like Firefox.<br>
So maybe it should be an option again.<br>
<br>
I'd suggest that we enable zRAM by default on Lubuntu and set<br>
swappiness to a lower value.<br>
Compression/decompression in RAM is something that a 586 cpu can do<br>
easily so it's always faster than reading or writing to the swap. It<br>
also decreases read/writes for your hard disk due to decreased use of<br>
on-disk swap. This is a plus if you're using SSD.<br>
<br>
Thanks!<br>

zram really should be enabled by default. There are now downsides to it.<br>
Tweaking the sysctl.conf swappiness is however another question. I would recommend leaving it at the default value.<div class="HOEnZb"><div class="h5"><br>
