Pretty but slow.
The new interface is very pretty, but it is also VERY slow and unresponsive. It takes about three seconds to get from the "Now Playing" to the "Main Menu". On 5G iPod video this was less than a second. I would gladly forego all the fancy animations if it would make the thing more responsive.

Hello Friends.
These are the facts, nothing anecdotal
I have owned/purchased 6 iPods over the years. The Classic is the first to disappoint me and the first one I have ever returned. I purchased my 80Gb. iPod Classic at the Apple store on September 9th and took it back a week later. The slowness described elsewhere here was too severe for me to tolerate and too much of a distraction.
I have over 100 playlists, most smart. When clicking "Playlists" from the main music window, the 30 second screen time would actually black out the screen before the playlists would appear (i.e. it took more than 30 seconds before the sub menu's would appear).
Additionally, as many other's have said, most menu transitions were taking 2-4 seconds.
On a positive note, I will say the sound quality was excellent, but the buggy, slow interface was too much. This is the first time Apple has let me down.
At least the store manager waived the $24 restocking fee.

My 1st Generation time capsule won't connect to the internet thru a new motorola sb6121 - get continuously flashing yellow light. Using a router in between the modem and capsule yields good but slower connection to internet. Any thoughts?
Thanks for your response
Let me give the history - I started with an Apple Express being fed thru a D-Link EBTR 2310 cable Router from an RCA DCM315 Modem (Pure). Comcast service all the way.
Got the 1st generation TC in 2008 and merely replaced the Airport Express with the TC. Worked ok
A year or two ago I did try removing the modem and feeding the TC directly from the modem. Resulted in the same condition I have now - Continuous flashing amber on the TC. So I put the router back in the chain.
Some time later, at the recommendation of a Comcast rep, I replaced the router with (a Belkin F5D 5231) to see if speed and dropout problems would be improved. I thought it helped some at the time but now I am not so sure.
Last week I decided to see if a new modem would help with download speeds. So I got another pure cable modem (Motorola SB 6121- high on the Comcast recommended list).
Got up and running easily with Comcast help and with the modem connected directly to a computer.
Next I put the TC in the link and again could not get past the TC continuing to flash amber. Although I did get connected to the internet with this configuration I lost connection two both of my printers - one connected by USB and the other wirelessly to the TC. Again everything works fine when I put the Belkin router back in the system.
However with the router in there, the modem shows the downstream connection to be 10/100 ethernet speed. (Modem light changes color for indicating speeds.}
I have gone thru all of the combinations of powering down/ up, but all stays the same.
I can live with what I have but something still doesn’t seem right.
Thanks again -
LR4.1 RC2 Remove Chromatic Aberration excellent, but slows display

Can somebody tell me what is going on with the last update of Mountain Lion 10.8.2?? Since then my computer is pretty much slower and blocken on Safari.
First of all, why did you say yes to Nero Back up before researching what it does with files already on the HDD? When I install Nero, the Back Up is the first thing I disable, it is a nagging pain, there are much better backup programs available. There are several file recovery programs out there to recover deleted files, that is, if that is what happened. Also, if you haven't overwritten the files, so you should be able to find them.

New Time Capsule, Fast internet but slow on loading video?
Just install TC in ethernet connection and used the Wifi for my laptop, The problem is the slower loading of video from youtube or even @ the apple site's to my mac and even to my portables!?
I didn't have this kind of problem even before installing the TC and tried reseting my safari thinking maybe it would make it load faster. Please help!OK I tried to separate the 5ghz and 2.4ghz names by going into wireless/wireless options and selecting the first checkbox.....didnt work. I tried using my Belkin router as a wireless access point. My iMac will connect to the Belkin and the TC but iPhone still wont connect to neither the Belkin nor the TC. I tried turning off NAT .....didnt work. I have pretty much tried every setting in Airport Utility and my iphone will not get internet. Would reverting to an old firmware version be worth a try? Is this safe to try?

Is it possible to Not Sync the app into itunes?Did you manage to get it working mine disappeared after I while I managed to download it but now my laptop/iTunes won't recognise my iPhone!

Hi all,
I have an old Mac mini that's from around 2008 and runs on Snow Leopard. I also have a brand new Macbook Pro with retina display that's running Mountain Lion. Both running iTunes 10.6.3.
I never noticed anything wrong with my MBP's connection speed until last night when I downloaded a free TV episode from iTunes. The download speed varied between 20KB/s and 40KB/s and it took me 7 to 8 hours to download a single episode. I checked my internet connection but there was nothing wrong with it, SpeedTest.net told me I had a download speed of 94MB/s and upload speed of 80MB/s, it was only iTunes that was unbearably slow.
Today I was browsing iTunes again and was planning to buy some movies, but again it took forever for the trailers to download. So I fired up my Mac mini just to see if it would be just as slow. Turned out my Mac mini could download the same trailers from iTunes at a much higher speed than my MBP (around 3MB/s on the ones I tested).
So what gives? They are on the same Wifi network provided by an Airport Extreme, and although my iPhone and iPad are also connected to it, no one else is doing any heavy duty downloading.
Thanks in advance!

Ever since I upgraded my Firefox to 4.01.1, everthing loads much, much slower.......I can go make a coffee while the page loads. Sometimes, it is soooooooooo slow, that it times out and I have to start all over again. Even when I sign on and load google, sometimes it takes forever.
I also do not like the toolbar at the top. It's grey and hard to read, what is wrong with white?
Can I revert back to the earlier version of Firefox? It worked much better. I use ancestry.com a lot and they even recommend a 3.??? version of Firefox.
Anything is better, so I don't have to sit and wait and wait and wait.Thank you, Zenos. I tried rolling back to v31.2.0, since I had not encountered problems prior to December. However, that didn't help. So I followed your valuable suggestion to revert to v24.6; that seems to have done the trick.
I would like to mark this problem as "Solved" -- the rollback seems to have worked. However, since my original post was a complex mix of things, before I do that, should I post the individual problem sets that I had noted (address fields/nicknames problems -- numbers 1-3; default font problem -- number 4; attachment reminder problem -- number 5) as separate issues which have not been solved?
Do you know if these various issues are being worked on? I'm glad to have the temporary fix of rolling back to an earlier version, but I'd like to get back on the current update schedule at some point if and when these problems have been corrected.
Thank you again! -

Hi everyone! Previously my S5200UK was upgraded from 1GB RAM to 2GB with a newer BIOS of V3.21
(See http://h30434.www3.hp.com/t5/Desktop-Hardware/Can-I-increase-RAM-size-if-I-upgrade-the-BIOS/m-p/1302... )
Thanks to Paul Tikkanen's help then I got the machine working fabulously but thanks to Microsoft's decommisioning of XP I decided to upgade to Windows 7 professional. The minimum requirements are 1GHz CPU and 1GB RAM. My AMD CPU is 2.08GHz but its performance is 2.6GHz equivalent. The RAM is 2GB and I have upgraded the HDD to a new Seagate SSHD SATA 1TB hybrid (with 8GB SSD incorporated). I used the exact drive on another machine a dx2000mt and WOW what a difference to boot speed (30sec) 1min with programs installed and data restored. (and that is usable desktop). I also fitted the ATI Radeon 9600 LE 128 MB AGP graphics card as recommended by Paul and a new 500W supply. I did not expect any problems as the 7 upgrade (clean install) on the dx2000mt went like a dream. Anyhow, this is the problem. After installing windows, all the updates and Norton Internet Security (NIS) the machine uses 100% processor and 25% RAM as I attempt to open NIS or use Internet Explorer. I can hear the CPU fan speed up every time it executes any small task and CPU shoots to 100%. With opening NIS there are two nis.exe processes using 50% CPU each! Any small demand of a program results in ultra slow operation. I put Win 7 on my old laptop with 1.5GHz CPU and 2GB RAM and that is great! I cannot believe that this S5200UK machine is limited by the CPU or RAM as it more that meets the requirements. I have obviously installed drivers (most came with Windows 7 and the others from a driver update program). There are no warnings or conflicts in the Device Manager and I have tried reinstalling everything again twice but it is always the same. I even tried changing the HDD to an IDE 80GB 7200rpm one but it was even slower! I also tried removing the graphics card but no change.Oddly I ran a performance test progam and, other than the memory, it came out better that the dx2000mt!!!! Has anyone got any suggestions as to what is causing this?
PS: The o/s is OEM for refurbished pcs on genuine hologram disk (no service pack but this was done via Windows Update) I will be very grateful if anyone out there can save my bacon. Thanks.Hi:
The only recommendation I can offer based on what you have posted, would be to ditch the Norton Internet Security software and just run it with Microsoft Security Essentials.
That free antivirus/antimalware software uses very few system resources.
http://www.microsoft.com/en-us/download/details.aspx?id=5201
You would also need to use the Norton uninstall tool to make sure it cleans out all traces of the program.

Query Fast In SQLPlus and Toad but Slow Otherwise
Environment is Oracle 10g on AIX with 10g drivers on Windows XP as the client. Several queries run in less than 9 seconds in Toad and SQLPlus but take hours or never return in Business Objects Deski, MS Access, and SQL Server SSIS. The exact same SQL produces completely different explain plans based on if it is run from Toad/SQLPlus vs the other products I mentioned. All the software is on the same XP machine and does not use middleware. 99 percent of our queries will run fast or slow in all products. What is it that Toad and/or SQLPlus does to run the queries fast? Why does Oracle change explain plans based on what application connects to it? The goal is to run Business Objects reports from Oracle. Any help or direction for further troubleshooting would be appreciated. Thank-you.
Charles, on the XP machine I selected the Admin option when installing the client. The software should be 10g R2. Below is the information requested. If you need more please let me know. Also, I am asking our DBA to check the bitmap issue.
I appreciate the help. Thank-you for taking your time...

Query with same explain-plan but slower in one env
Hi there
I have a stored procedure which is executed from a web application. It contains a query (insert-select-from statement). When this stored procedure is called by the web application in PROD, it takes 13sec but it takes 19sec in TEST env. I checked the explain plan for this insert statement in both instances and it is same (see below). Actually, the cost is lower in TEST env.
ENV: Oracle 10gR2 EE, on ASM - RHEL 64bit
The TEST server is on a better/faster hardware and will become the new PROD in near future (faster and 16 CPUs vs 8 in PROD, high performance SAN, 132GB RAM vs 96GB in PROD, etc). The TEST database has exact same init parameter and version/patch level as current PROD. So the application is being tested against it at the moment.
Here are the explain-plans from both environments:

What else can I check to find out why the query is slower in TEST env?
Please advise.
Best regardsHere is some more info. The query is below:
select distinct dr.line_num
,row_number() over (partition by di.HEADINGNO,di.DIRECTORYNO order by reportyear,to_number(di.monthno)) monthposition
,di.SATID,di.REPORTYEAR,di.MONTHNO,di.MONTHEN,di.MONTHFR,di.HEADINGNO,hn.NAME_EN,hn.NAME_FR,di.DIRECTORYNO
,di.SUPERDIRECTORYNO,di.PRINTDIRCODE,di.DIRECTORYNAME,round(to_number(di.IMPTTOTAL)) imptotal
,round(to_number(di.IMPBEST)) impbest ,round(to_number(di.IMPTAVERAGE)) imptaverage
,round(to_number(di.CLICKTOTAL)) clicktotal,round(to_number(di.CLICKBEST)) clickbest
,round(to_number(di.CLICKAVERAGE)) clickaverage
,round(avg(to_number(impttotal)) over(partition by di.HEADINGNO,di.DIRECTORYNO)) avgimp
from satdataimport di,tmpg_clicks_hdgs hd,tmpg_clicks_dirs dr, months12 m12, ref_west_category hn
where di.headingno = hd.id
and di.directoryno = dr.id
and dr.line_num=hd.line_num
and di.reportyear = m12.year
and di.monthno = m12.month
and hn.CATEGORY_CODE = di.headingno
order by di.headingno, di.directoryno,di.reportyear,to_number(di.monthno)
The largest table is "satdataimport" in the query has "12274818" rows. Rest of the tables are very small containing few rows to less than 4000 rows.
I have refreshed the statistics of the larger table but this did not help either. Even a simple query like "select count(*) from satdataimport" is taking 15sec in TEST while it takes 4Sec in PROD when I run it from TOAD.
The other strange thing is that when I run this stored procedure from TOAD, it takes 200 milli sec to complete. There is a logging table to which the stored procedure records the elapsed time taken by this INSERT statement.
Since this query is in a stored procedure being called from the web app, the QA team wants quicker response. Current PROD is faster.
The tables have same indexes, etc and contain identical data as that in PROD (were refreshed from PROD yesterday).
What else can I check?

Fast wired connection, but slow wifi
Hi, I can get around 60mbps on my wired connection from my desktop but on wifi I can only get around 2-3mbps. However if I reset the home hub or sometimes if I change the channel (currently it's on channel 9) then I can get around 50mbps on wifi but over time (perhaps a day or two) it'll slow down to 2-3 again.
Strangely upload isn't affected by this - only download.
The only devices connected via wifi are my android phone and my ipad so it's not a case of them slowing it down.
Any suggestions?
Thanks,
Gregorwhich router are you using?
you can try downloading inssider3 (istumbler if MAC) and then run it. This will show the broadcasting networks round about you and their channels including your own. If you then enter your router and change your wireless channel to a free or less congested channel.
inssider3.1.2.1
