Why is 10.0.9 so much slower than 10.0.7

I was having no problems with 10.0.7, but after being constantly 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?

    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.

    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.

    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).

    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.

    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.

    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.

    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.

    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.

    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?

    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?

    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.

    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.

    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.)

    (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.)

    Thanks--I will try to get around to it, then send you the data (if it
    shows a significant discrepancy).

    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.

    Actually, this is a new topic, but I am adding it here since I have a history with you.
    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:

    /Users/sharonboothby/Desktop/V35LmCbO.zip.part could not be saved, because the source file could not be read.

    Try again later, or contact the server administrator.

    What does this mean?

    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?

    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.

    I had tried it 3 times before I contacted you. I switched to Opera,
    which gives me all the features of Gmail, but was so slow I could not
    stand it. So I tried downloading your 17 beta again & it worked. No
    idea what was different. Anyway, why am I now unable to get all the
    features of Gmail? Had no problem on my other iBook but it was running
    10.5 and this one is 10.4.11. But the whole point of TenFourFox is to
    run on 10.4, right?

    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.

    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.
