Parent article: A grumpy user's browser review

I'd strongly recommend you invest some time into getting Konqueror to
work with your current setup. If it isn't, something is broken with your
installation, I have been running Konqueror under GNOME or even remotely
on a CDE desktop for a year (or maybe two?) now. I'm running the latest
released version of Konqueror (3.2) from the official rpms on ftp.kde.org
on Fedora Core 1.

1) 98MB for a browser instance? That's crazy. I have SEVEN konqueror
processes running right now, and the total memory obtained from ps
-o'pid,rss,args' is 186MB. That's an average of 26MB/instance. I always
thought that was too much :)

2) Your example render takes a little over 5 seconds for Konqueror to
render the page *remotely*! I'm timing from when I click 'refresh' to
when the page is complete. I saved the page to my hard drive, repeated
the test from there - local render time is approximately 2.5 seconds.

3) I'm not even sure what you're talking about with this 'typeahead find
death grip'. I don't think this is a problem in Konqueror. You can
disable animations (or even set it to 'only animate once'). Fonts are
pretty. Bookmark editing works. It doesn't suffer from the 'users are
stupid don't let them configure anything' syndrome.

A long-satisfied Konqueror user.

I should have pointed out that my rendering time tests were not done on the fastest machine on the planet. I'm still using the Penguin Computing box that I reviewed in LWN back in 1999... Time to do something about that.

Ah, good point. I'm running on a 1Ghz P4 with 512MB ram.

That really doesn't tell us much. How much memory does it take to run a single instance?

Actually, I suppose you want to know konqueror + all the KDE support
processes. Hmm. Another good point. Plus I should have counted the IO
slaves in with my original number.

sysadm 22680 konqueror
sysadm 4600 kdeinit: Running...
sysadm 8312 kdeinit: dcopserver --nosid --suicide
sysadm 8624 kdeinit: klauncher
sysadm 12848 kdeinit: kded
sysadm 7960 kdeinit: kio_file
sysadm 7940 kdeinit: kio_file
sysadm 7944 kdeinit: kio_file
sysadm 7948 kdeinit: kio_file
sysadm 7952 kdeinit: kio_file
sysadm 8712 kdeinit: kio_http
sysadm 8708 kdeinit: kio_http

Total: 114288. A bit higher, unfortunately.

FYI, the 'kio_file' and 'kio_http' are slave processes shared among all
konqueror instances, even on my account with 7 instances, I still have
the same number. I believe the number of io slaves is configurable,
somewhere.

--Thanks for that ps command example; I used it to see the RSS on Opera 6.12 with (27) windows open tabbed, and got this:

1234 1088 /bin/sh /usr/bin/opera
1236 58092 /usr/lib/opera/6.12-20030305.1/opera

--56MB for 27 windows ain't bad.
