59228 - ftp directory listing block X server under Linux

Status: RESOLVED FIXED

(Core :: XUL, defect, P3)

Description

[AM]

When I open the above address by starting at the top of the

ftp.mozilla.org tree and opening the directories there is a dreadful
performance problem when opening the nightly directory.
It takes 15 second to list the directory. During this time
the mouse will hardly move on the screen. Mozilla seems really to
hammer the X server at this moment.
Gecko/20001105 build, downloaded from ftp.mozilla.org

updating component and setting default owner.

->bryner to figure out whether this is more excessive round trips to the X
server, or perhaps rdf or ftp delays.  p3/moz0.9

I'm not seeing any severe performance problems doing an ftp listing on a current
build.  Can you try to reproduce on a more recent nightly?  Also, what CPU speed
and RAM do you have?

I ran on Gecko/20010111, Linux
Running under Suse/x86

I tried two machines:
stubbs: Bi-processor pentium II, 450Mhz, 256M ram, Matrix G400, Xfree3.3.6
holbein: Monoprocessor Pentium III, 800 Mhz, 256 ram, NVidia GeForce, Xfree4.

Both machines have performance problems with ftp listings (I am using
modern skin)

To factor out the network speed I tried listing a local mirror of redhat7 rpms.

Stubbs:
It takes about 20 seconds to list all the files, the X pointer
is very slow to react during this time as per report.

Holbein:
The X pointer remains fluid. However the directory listing takes
50 seconds.

As a reference netscape 4.7 finishes in about 3 seconds.

So I tried this in a build and I didn't have any problems with it.  Looked fine
here.

I don't think we're going to get anywhere on this bug specifically; dougt's ftp
changes and changing the directory viewer to use <outliner> will probably help
ftp performance though.

Setting moz1.0, unless someone wants to mark this FIXED.

[Brian Ryner (not reading)]

Is this still happening?

Comment 9

[Christopher Blizzard (:blizzard)]

I haven't seen anything like this in a long long time.  ftp is working pretty
well these days.

Well the default FTP display has been changed 
since the report. FTP just gives a plain view of
files, rather than a tree view, which was killing
all performance

I am marking as fixed.
