pestered to upgrade, I did. Why is 10.0.9 SOOOOOO much SLOOOWER?
Everything is is the same, but it takes forever to load the same
things I had no problem with before. Can't I just go back to
10.0.7? What was the urgency about upgrading?</p></div>SBoothbytag:tenfourfox.tenderapp.com,2012-01-07:Comment/198379762012-10-20T00:57:12Z2012-10-20T00:57:12ZWhy is 10.0.9 so much slower than 10.0.7<div><p>I don't have an explanation for you about the speed, other than
to say that there were no changes made I am aware of that would
affect performance, but the bug repaired by 10.0.9 was publicly
released and can cause the browser to be exploited or leak data.
For this reason it is imperative for people to update.</p>
<p>If you like, you can try 17 beta and see if this is faster for
you. Although it is a beta, it is generally safe for day to day
use, and 17.0 will replace the TenFourFox 10 series in November.
However, I would strongly advise against using any version of
TenFourFox 10 before 10.0.9.</p></div>Cameron Kaisertag:tenfourfox.tenderapp.com,2012-01-07:Comment/198379762012-10-23T23:27:16Z2012-10-23T23:27:16ZWhy is 10.0.9 so much slower than 10.0.7<div><p>I have found the same thing, actually. I don't have an
explanation, but it is clearly slower (on a g4 1.5 ghz Powerbook
with maxed RAM, 7450 build).</p></div>Jonathantag:tenfourfox.tenderapp.com,2012-01-07:Comment/198379762012-10-24T00:01:00Z2012-10-24T00:01:00ZWhy is 10.0.9 so much slower than 10.0.7<div><p>I'm going to need a benchmark or objective measurement before I
can explore this further, and bear in mind with 17 around the
corner, the most likely suggestion will still be to update when it
becomes available. I can't reproduce any noticeable difference on
my test units between 10.0.7, 10.0.8 and 10.0.9.</p></div>Cameron Kaisertag:tenfourfox.tenderapp.com,2012-01-07:Comment/198379762012-10-24T00:18:41Z2012-10-24T00:18:43ZWhy is 10.0.9 so much slower than 10.0.7<div><p>I have 1.33 ghz G4 iBook/512mb RAM, also 7450 build. Yes this is
ridiculously low RAM, but the point is I had no problems with
10.0.7. I really have no way of benchmarking, but I simply cannot
load the same sites I was using before in any reasonable time. Am
constantly force-quitting & relaunching.</p>
<p>There is such an extreme difference that I wonder about 17, if
your test units have shown no differences. I'm sure your test units
have a lot more RAM.</p></div>SBoothbytag:tenfourfox.tenderapp.com,2012-01-07:Comment/198379762012-10-24T00:24:40Z2012-10-24T00:24:40ZWhy is 10.0.9 so much slower than 10.0.7<div><p>They do. If the RAM ceiling is the issue, you're going to find
that problem more and more. I'm considering not supporting any less
than 1GB of RAM for 18+, for example, and 512MB is already a very
tight fit for 10 and 17. None of the test systems here have less
than 1.25GB. While I support 512MB systems still, I only support
them insofar as to make sure they work. Performance is another
story.</p>
<p>The iBook you have can take up to 1.5GB (I have the same iBook,
running 10.0.9 and 17 beta with a full RAM loadout) and a 1GB
SO-DIMM for it will be around $50 well-spent.</p></div>Cameron Kaisertag:tenfourfox.tenderapp.com,2012-01-07:Comment/198379762012-10-24T00:38:40Z2012-10-24T00:38:41ZWhy is 10.0.9 so much slower than 10.0.7<div><p>I have bought the RAM, just haven't gotten around to installing
it yet (MUCH less than $50, btw.) But the reason people are using
TenFourFox is that they are using older machines with less RAM. Why
not take this into account with your upgrades?</p></div>SBoothbytag:tenfourfox.tenderapp.com,2012-01-07:Comment/198379762012-10-24T00:40:04Z2012-10-24T00:40:05ZWhy is 10.0.9 so much slower than 10.0.7<div><p>I have 1.25 gb of Ram on my 1.5 ghz Powerbook, however, and I
have the same problem. This is also true for beta 17--slow,
spinning disk, etc. What kind of benchmark data would you need?</p></div>Jonathantag:tenfourfox.tenderapp.com,2012-01-07:Comment/198379762012-10-24T00:43:28Z2012-10-24T00:43:28ZWhy is 10.0.9 so much slower than 10.0.7<div><p>Because the point of TenFourFox is to bring as modern a browser
as possible to Power Macs, and that's going to require more memory
to do so as we need to upgrade system libraries and compilers, as
well as dealing with the rapidly growing Mozilla code base.</p>
<p>When it gets to a point where more RAM is required than the
majority of machines are capable of, then we'll have to have that
discussion. But we're not to that point yet.</p>
<p>Jonathan, I would accept a comparison between Dromaeo,
SunSpider, V8 or Peacemaker on the relevant versions showing a
statistically significant regression. But if you're seeing issues
with 17 also, I really don't know what to tell you. My internal
benchmarking shows 17's JavaScript is 10-20% faster than 10's, for
example, so there is an obvious difference between your system and
my test bank. (TenFourFox is tested routinely on four machines
before release.)</p></div>Cameron Kaisertag:tenfourfox.tenderapp.com,2012-01-07:Comment/198379762012-10-24T00:44:56Z2012-10-24T00:44:56ZWhy is 10.0.9 so much slower than 10.0.7<div><p>(It also goes without saying that such tests should be done on
clean profiles. Addons can unpredictably affect the browser, as
well as cache and pref cruft.)</p></div>Cameron Kaisertag:tenfourfox.tenderapp.com,2012-01-07:Comment/198379762012-10-24T00:48:04Z2012-10-24T00:48:04ZWhy is 10.0.9 so much slower than 10.0.7<div><p>Thanks--I will try to get around to it, then send you the data
(if it<br>
shows a significant discrepancy).</p></div>Jonathan Sadowtag:tenfourfox.tenderapp.com,2012-01-07:Comment/198379762012-10-24T12:05:40Z2012-10-24T12:05:40ZWhy is 10.0.9 so much slower than 10.0.7<div><p>My benchmarks on a low-end machine (400 MHz G3/512 MB RAM) show
no regression between TFF 10.0.8 and 10.0.9, and TFF 17 is
considerably faster at pure JS. I haven't noticed a slowdown in
real life.</p></div>Chris (chtrusch)tag:tenfourfox.tenderapp.com,2012-01-07:Comment/198379762012-11-08T04:33:24Z2012-11-08T04:33:25ZWhy is 10.0.9 so much slower than 10.0.7<div><p>Actually, this is a new topic, but I am adding it here since I
have a history with you.<br>
I installed 17beta and did not have any of the slowness, but it
would quit often enough to be annoying. Haven't complained since it
is beta. Then I installed my 1gb ram stick & a new battery
& can't get my 1.33 ibook to start up. So I got out my older G4
ibook 1.2 which I haven't used for awhile. Installed 10.0.10 on it,
but am getting gmail messages that I need to upgrade my browser to
use gmail features. So I just tried to download 17 beta & get
this message:</p>
<p>/Users/sharonboothby/Desktop/V35LmCbO.zip.part could not be
saved, because the source file could not be read.</p>
<p>Try again later, or contact the server administrator.</p>
<p>What does this mean?</p></div>SBoothbytag:tenfourfox.tenderapp.com,2012-01-07:Comment/198379762012-11-08T05:05:36Z2012-11-08T05:05:36ZWhy is 10.0.9 so much slower than 10.0.7<div><p>It almost sounds like the temporary file used for the download
got deleted before it was processed. Do you get that error every
time you try to download it?</p>
<p>I haven't had any reports of abnormal instability with 17 beta,
but it sounds as if your iBook G4/1.33 has a hardware issue,
unfortunately.</p></div>Cameron Kaisertag:tenfourfox.tenderapp.com,2012-01-07:Comment/198379762012-11-08T06:13:20Z2012-11-08T06:13:20ZWhy is 10.0.9 so much slower than 10.0.7<div><p>I had tried it 3 times before I contacted you. I switched to
Opera,<br>
which gives me all the features of Gmail, but was so slow I could
not<br>
stand it. So I tried downloading your 17 beta again & it
worked. No<br>
idea what was different. Anyway, why am I now unable to get all
the<br>
features of Gmail? Had no problem on my other iBook but it was
running<br>
10.5 and this one is 10.4.11. But the whole point of TenFourFox is
to<br>
run on 10.4, right?</p></div>SharonBtag:tenfourfox.tenderapp.com,2012-01-07:Comment/198379762012-11-08T15:28:26Z2012-11-08T15:28:26ZWhy is 10.0.9 so much slower than 10.0.7<div><p>I replied to your other copy of this question, but for people
tracking this ticket specifically, I have no explanation for why it
would work one day and not the next. FTR, I'm logged into Gmail
right now with the current 17 beta. It's not superfast on a G4, but
it does work, so I can't replicate your issue here either.</p>
<p>Are you positive this is the only application you're having
trouble with? Opera is no speed demon, but it shouldn't be as slow
as you describe either. It certainly isn't on my own iBook
G4/1.33.</p></div>Cameron Kaiser
