New Infinity installation is slower than ADSL - Su...

BT just rolled out Superfast broadband in my area so I signed up with BT. I was promised 13Mbps/1Mbs which was disappointing as it's nowehhere near the 'Superfast' speeds that BT advertise. I already have an ADSL line from TalkTalk which tests out at about 6.5Mbs/0.8Mbps so even though I will be paying 50% more at least I was promised that I would get double the speed. If only that were true!
A brand new line was run to the house on 20/5/2015 & the BT Homehib installed. However the speed is only 5Mbps/1Mbps & has not changed since installation. I immediately called customer support on the day of installation but they say there is nothing wrong with my line but clearly there is as I am not getting anywhere near a 'Superfast' speed not even the same speed as my exisiting ADSL line.
What do I need to do to escalate this & get the problem sorted? Clearly I don't intend paying 50% more to get an inferior 'Superfast' line from BT.

New OIF installation - Very slow response from OHS

Hi,
I've installed two instances of OIF 10.1.4.0.1 in order to create a test configuration to test XASP Attribute Sharing (i.e., we are not doing any other profiles).
Both OIF instances are using a separate instance of Sun Directory Server as its User Data Store, and both are using in-memory for Transient Data Store and have no Federation Data Store. Both OIF instances were installed similarly, using the "BASIC" installation choices, and are running on separate Redhat Linux servers.
The problem that we're seeing is very slow (10+ seconds to 30+ seconds) responses, even when we try to access a static HTML test page that we've placed in the OHS htdocs directory.
We've eliminated any networking problems as possibilities by a couple of tests that we've done, including shutting down the OHS and running a small, different test web server listening on port 7777. When we do that, response time for requests from that web server is almost instantaneous.
We are also seeing the same slow response when we try to access the test HTML page from the same server itself.
We have an SR open with Oracle, but so far, we've not been able to identify what the problem might be, so I'm hoping that perhaps someone else may have encountered this problem and have a resolution.
It is really puzzling because, as I said, this is a pretty vanilla default OIF installation, and it is doubly puzzling because even getting a tiny static HTML page is taking 10+ seconds. Also, I had installed OIF 10.1.4.0.1 on a Windows machine previously, and I don't see this problem on that earlier installation.
If anyone here has any insight into this problem, please let me know.
Thanks,
Jim

Hi,
I think I was able to temporarily eliminate this slow response problem. I think that the slow response problem is related to another problem that I posted about in the "Application Server - General" forum (see below, and Port 7200 conflict?
Jim
======= POSTED to Application Server - General forum ============
I think that I was able to temporarily work around this problem, plus another problem that I think is related (see: New OIF installation - Very slow response from OHS
What I did was to just comment out the "include" line for "dms.conf" in the Apache httpd.conf.
Doing that got rid of the "Address already in use" errors I was seeing in Apache error_log and also eliminated the slow response I was seeing from Apache/OHS (see that other post in "Identity Management" forum), BUT I am getting new errors about Apache not being able to find "htdocs/dms/Spy0".
I have the impression that dms is some kind of process monitoring system that Oracle has in 10gAS infrastructure? So, I have some questions:
1) What's the effect of dms not working?
2) Is it possible to just disable dms?
I hope that Oracle support can come up with a "real" fix for both problems, but in the meantime, as long as what I did doesn't break anything else besides dms, we can at least test the OIF stuff.

Why does the new version FireFox run slower than the old one?

I have a fairly new computer but Firefox runs slower than the older version. Can this be remedied?

That does not sound right. I recommend rebuilding your VI. Beore you do, open the top level VI and press contol-shift-run arrow to perform a manual binary recompile. This makes LabVIEW recompile the whole code. Most times you will not see anything happen but occasionally an error will surface. Be sure to save the VI then rebuild it.
You may also need to reinstall the LabVIEW run time engine and/or LabVIEW. I would start with the run time engine first.

New Infinity Installation. No internet connection ...

Hi.
Had Infinity installed on Thursday afternoon and was initially impressed with 40Mb+ download and 15Mb upload speeds.
However, at about 5.30pm webpages stopped loading. Rebooted the HomeHub3 and was ok again for about 15 minutes but then nothing for the rest of the night.
Internet was back the next morning but same thing happened again last night until about 11.15pm when it was back as if nothing had happened. Whilst there is no access, the HomeHub shows 3 solid lights. It's like there is a connection but its so slow that webpages time out. Tried using wireless connection and wired through Powerline adaptors. Also tried connecting directly to the router.
So for 2 nights out of 2 I've had no access to the net which is obviously not acceptable. Can anyone suggest anything that I can try? I will have access to a new router later today so I will try using that.

Hiya - same thing has happened to me - go BT Infinity2 installed last Tuesday, all ok 48mb down 9+up until Fri 18th May when it dropped out and was v.slow. No internet until Saturday 19th during the day. Then 40+mb ok until 2330 Saturday 19th dropped out log shows CWMP:session connect host failed - again no internet until Sunday 19th - a call to 0800 111 4567 remedied the situation with "a fault at the exchange - working the the exchange" then I got 48mb dowm, 9mb up until.... 2330 on Sunday when the signal dropped out - like you, SensiBlue, three bluse lights and I can ping a server so theres a connection, but the log again shows CWMP:session connect host failed and CWMPSL certificate error. No internet again all night - a further call to tech help merely resulted in the response than an engineer will come to my house - in four days time! to see if its a fault on my line. This hardly seems likely as I can ping out, and the line was checked - just 6bB loss only on Tuesday. I have tried a new router too - no difference. This intermittent fault seems to be fairly common on the forums too. Anyone got an idea? Like you say, SensiBlue, its not acceptable.

Airport Drives Me CRAZY! New 802.11n Network Slower Than Old 802.11g/b

I've been using Macs since 1988 and consider myself an advanced user. However, every time I setup a new Airport wireless network or re-configure an existing one, I feel like a helpless newbie trying to figure out how to open a folder on my desktop. No matter how many times I read the manual or the help files or these forums, I can never grasp what seems like it should be a simple path from A to B to C.
Anyway, here's my current situation: I've been successfully (I think) running a 6 year old AP Extreme Base Station [AE] (in my home office addition) and 2 Airport Expresses [AX] (one AX roughly 15 feet from the base station--through sheetrock, and the second AX roughly 30 feet from the first AX--through sheetrock and some wooden stairs. (so roughly 45 feet from AE to 2nd AX). It wasn't the speediest thing going but it did the trick with older Macs.
I recently bought a MacBook Pro which supports 802.11n. I most often use this laptop at the point in the house furthest away from the AE (Base Station) The AE (Base Station) is in my home office connected to my MacPro desktop (see #1 below). In addition, the family iMac is also in that room furthest from the AE. Using the new MacBook Pro with the old 802.11/g/b network turned out to be painfully slow. I was experiencing the same slow network connection my family has complained about for years with their older Macs and 802.11g/b.
I decided it was time to upgrade the whole network, if only to speed up my MacBook Pro connection. Bought new 802.11n Airport Extreme (MC340LL/A) and 2 new 802.11n Airport Expresses (MB321LL/A). Setup did not go smoothly. Again, my normally competent Mac persona was reduced to a babbling three-year-old. Had three different Apple techs on the phone trying to help me through it. Got different, contradictory instructions from the last two. Finally got all three units working, only to find that not only does my MacBook Pro seem even more sluggish than when connected to the old 802.11g/b network, but my wife tells me web pages are taking at least twice as long to load as with the old network.
As concisely as I can lay this out:
*1. Airport Extreme (Base Station)*
Connected via Ethernet from its WAN port to my Comcast cable modem. One Ethernet (LAN) port on that AE is then connected via Ethernet to my Netgear 8-port Ethernet switch. Ethernet from switch to Ethernet port 1 on my MacPro. (MacPro does NOT have an Airport card because I forgot to order one. Also I confirmed that this setup was functional by connecting to the AE wirelessly with my MacBook Pro showing the name I'd given the new network prior to adding the two AX's to the mix).
Some Airport Extreme settings of note (all accessed via "Manual Setup" button):

SETUP/GOALS:
With Airport Extreme (Base Station) as the starting point, have the two Airport Express units with the strongest, fastest signal possible, provide Internet access (and file sharing, iTunes speakers capability) to three Macs (one older iMac, one older PowerBook and my new MacBookPro). Again, I believe my new MacBook Pro is the only one with 802.11n support, so I don't expect the other Macs to take advantage of the speed boost offered by the three new 802.11n devices.
+Any and all help with this will be greatly appreciated. Thanks!+

{quote}With the AirPort Extreme, in the AirPort panel, Wireless tab, click on the button for "Wireless Network Options", check the box for "5 GHz Network Name", and enter a different network name. (That can be trivially different, such as the name of the main network suffixed with an underscore and the digit 5.) Once configured that way, connect your "N" gear to each network in turn to see if one is any better than the other. (If you're wondering what effect this would have, it allows segregating your "N" gear from the older gear to prevent the older gear from slowing down your network. However, distance and interference from things like walls may negate any advantage.){quote}
William: I was gone most of yesterday, but had a chance to implement your recommendations today. I added the 5 GHz network as you suggested, but in order to connect to that at all with my 802.n11 MacBokk Pro, I need to be within a few feet of the AE (base station). If I try to access that network even from the next room (well within reach of both the AE and the livingroom AX, I get one bar and "failure to connect" messages just trying to logon to that network.
However, I did some experimenting that (as of right now, anyway) resulted in much faster network access, not only from my MacBook, but also from the older iMac which is the furthest Mac from the AE. According to my wife, that iMac is "loading web pages faster than I've ever seen them!"
Here's what I did:
1. Moved all three units to places where it seemed they would have the least amount of interference with the clearest path from unit to unit, also raising the height of both AXs from about 2-3 feet from the floor to about 5-6 feet from the floor.
2. Changed one setting on the AE (base station): Wireless Tab > Wireless Network Options > Multicast Rate ---> Changed this from Low to High.
I have a feeling the location shifts made the real difference, but I will try changing the multicast rate back to "Low" just to see what happens.

The new iPad: Does your SmartCover wake up the new iPad a little slower than iPad 2?

Hey guys! I got my new iPad (32GB with iOS 5.1.1) one month ago. Now I found it takes longer to wake it up than my old iPad 2 with SmartCover. I have to wait for 1-2 seconds before the screen lit up. However, iPad 2 only take half seconds or less, seems instantly...
I wonder if anyone has the same problem like me? Is it something related to the iOS or can I change for a faster one (if the problem is hardware-related)? Thanks for your contribution.
Darling kim

Hi Simon,
Thanks for your detailed reply. I can't see any slow response on iPad 2 even with lots of app running background I think may be this issue is by design for iPad 3, or may be caused by the iOS 5.1.1 as my iPad 2 still running its original iOS 5.0.1...
This issue is rarely reported, so may be it's an exception for both of us.
I was concerned about this, but not that much now. The stunning Retina makes me forgot it! I bet you feel the same
Another thing, does your new iPad is a little darker than iPad2 when setting to maximum brightness?
Kim,

New Infinity Installation

Got Infinity on order, read the stuff - confused!
My master socket comes into the house at the front door - no power socket near there. I have four wired extensions, all hidden cabling, all near power sockets. So - how do I get the new hub without any surface wiring if it has to be near the incoming master socket?
My current BT hub is in the bedroom (office!) and of course with BT Vision have the plug ins
Definitely no surface running of cables either for power or for extensions. If we need to have the master socket next to the hub and power, then there may be a need for external cable runs and drill through walls to fit a new socket. Any ideas? And will the engineer play ball?
Solved!
Go to Solution.

the engineer can change any socket to become the master for free ask them when they arrive remember you need two power sockets available one for the hub one for the modem

Can anyone explain why my new Apple TV is slower than my ROKU player ?

I have a DSL internet connection I purchase movies from Amazon & iTunes. My Amazon purchases are available instantly while my Apple purchase is telling me 2 hours remaining to download ! What is that about ?!!!!! I am using the same DSL connection for both purchases. I am returning my Apple TV sticking with my ROKU PLAYER a much better product and more options other than iTunes & Netflix. I have Amazon to rent from as well plus 100's of other channels to choose from.
Disappointed loyal Apple fan.

Does your Mac have Wireless 802.11N? Both the router and the Mac must have N enabled to get the speed. ATV to Router will be at N speeds, but this does not matter if the bottleneck is between the Mac and the Router.
Newer iMacs and MacBooks have N, If you bought before 2007, maybe not. Maybe check your system profiler to see which you have.
For your initial sync, you may want to use an ethernet cable. See the Apple Knowledgebase article on how to do this. Once the initial sync is done, the incremental syncs should go pretty well with either g or n.
I have n. My wife's Mac has g. She is able to stream video to the ATV with no problem. We are using the Airport Extreme, though, not the Belkin.

Does anyone else think the new lion upgrade is slower than snow leapard?

After upgrading to Lion it seam everything is slower. Opening programs, running processes, working in programs. Yahoo account on foxfire I have to reload the mail about three time to get to it. Not real happy with the upgrade at this point.

I have started "top -o cpu" in a terminal and it seems that the process "mdworker" is taking up quite some cpu, together with some other kernel stuff.
Some searching on the www, and I learned that this could be due to the indexing activities mentioned earlier. It's odd tho. When I dive into it, it seems to be opening files on my Time-Machine device. Is that normal practice?

If you want to clean up your hard drive some, here are some of my tips, also.
Hard drive getting full or near full?
Do a search for and downlaod and install OmniDisk Sweeper and OnyX.
Here are some of my tips for deleting or archiving data off of your internal hard
Have you emptied your iMac's Trash icon in the Dock?
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Other things you can do to gain space.
Delete any old or no longer needed emails and/or archive older emails you want to save to disc, Flash drive/s or to ext. hard drive.
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, Flash drive or ext. hard drive and/or delete any old documents you no longer use or immediately need.
Uninstall apps that you no longer use. If the app has a dedicated uninstaller, use it to completely uninstall the app. If the app has no uninstaller, then just drag it to the OS X Trash icon and empty the Trash.
Also, if you save old downloaded .dmg application installer files, you can either archive and delete these or just delete the ones you think you'll never install, again.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its thing initially, then go to the cleaning and maintenance tabs and run all of the processes in the tabs. Let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
If you have any other large folders of personal data or projects, these should be thinned out, moved, also, to the external hard drive and then either archived to disc, Flash drive or ext. hard drive and/or deleted off your internal hard drive.
Good Luck!

Computer slower than when new

hello, i been noticing my mac acts slower than when new. im getting the little spinning color wheel alot now when i hardly ever saw it before. i ran my disk permissions and it seems ok. is there anything else i can do to make it fresh again? thanx 4 help

yes i ran them then and when it seemed slow. i havent added fonts that i know of, but i did add a canon mpc600 printer and it had software that may have included fonts im guessing. i ran permissions after that installation. inet seems like normal speed, im on ethernet cause my airport is the bugged type that 24"s have. works fine awhile then no longer connects for whatever reason. i gave up on wireless after weeks of problems. i ran onyx and i noticed immediatly my external drive opened without the spinning color wheel so i think its fixed now. thank you for your reply.

Brand new Macbook Pro slower than my 2006 Macbook

I bought a new Macbook Pro last month and upgraded the RAM to 4 GB and the hard drive to 500 GB. My previous Mac was a mid-2006 Macbook with 2 GB RAM.
I was expecting it to be noticeably faster than my 2006 Macbook (which is still running Tiger/10.4), but it isn't. Two things are particularly noticeable.
1) Startup time. The 2006 Macbook is 5 or 10 seconds faster starting up.
2) Safari. Safari is a couple of seconds faster loading identical websites on the 2006 Macbook. I tried updating Safari on the Macbook Pro to the new Safari 4 beta, and that is slightly faster, but still noticeably slower than on my Macbook.
I've tried running the set of Applescripts called "Maintenance" (available on the web) to do all regular maintenance tasks.
I've run software update. Everything is up to date.
Any suggestions of other things I should be checking to try to improve the speed of my Macbook Pro are much appreciated.
I find it really mystifying that performance is so noticeably worse on a brand new, much more powerful machine.
Thanks

Thanks for the replies.
In re the OS, I personally don't see many significant improvements in OS 10.5. Sure, little things here and there, but major power improvements over 10.4 that should cause startup time to be slower? I don't see it. I'm surprised in the design phase Apple's software engineers would allow longer startup time (always one of their biggest selling point over the Windows world) in return for such things as being able to hit the space bar in the finder to open a document quickly. I'm not using Time Machine, for instance, so that shouldn't be slowing down startup... or at least actually loading it in functioning mode shouldn't be slowing things down.
In re Safari, I'm doing as scientific a test as I possibly can here at home. Both computers sitting right next to each other, connected to the same network wirelessly, clicking on the same web link at exactly the same time. My 2006 Macbook is consistently faster at loading the page. Even more, it is significantly faster at loading the page to a "usable" point. For instance, if I click on the main page of the New York Times, the 2006 Macbook will load faster and will let me scroll down much earlier in the load process. On the 2009 MBP, the page shows up a few seconds slower, and it takes another few seconds more before the spinning beach ball stops and I can scroll down on the page. This is true both with Safari 3 and 4 on the MBP.
I just find it weird that a much more powerful computer, with a "new, improved" operating system and twice the amount of RAM, is noticeably more sluggish on these really basic tasks.
My next step is to go to the Apple store and try to compare mine to some other MBPs...
I have issues with some developments at Apple recently. For instance, the gen 2 iPod shuffle strikes me as a perfect design. Does it need to be smaller? Moving the controls to the headset seems really weird to me, much less convenient than the old one. I know that comment is OT, I just am starting to wonder about some decisions at Apple.
Not enough to make me complain seriously... I still vastly prefer Apple to the other options. But that sense I had for years that somebody really smart is paying attention to all these details and getting them right... that's starting to fade away for me. On the other hand, I do not have an iPhone and I think it's clear a lot of Apple's resources are going into the iPhone these days.

New hard drive slower than old one

Hello, my Seagate 120GB 5400rpm drive crashed 6 weeks ago and I made use of the warranty to get a replacement (refurbished) drive. I think this drive is no good because I have noticed a marked decrease in performance:
-Upon coming back from sleep mode the screen turns on but it pinwheels for several seconds, showing the time it was when I put it to sleep.
-My battery also lasts considerably less now. The battery is about a year old and had been lasting me up to two hours. It now doesn't last much more than one.
-I also tried to rip a dvd today and had to stop because it was going 5x slower than it had even on this drive when I first got it.
Is there anything else that could be causing me this decreased performance besides a subpar drive?
I have been in touch with Seagate again this weekend and they suggested I send it in for another replacement, which is fine, but is there a way I can copy all of this drive onto my replacement when it gets here? Or should I need to start fresh and reinstall everything on the new one?
Thanks.

You might want to check that you have selected a startup disk as "Macintosh HD" so the OS x knows where to boot from. If there is no selection under startup items in System Preferences then boot up is delayed by a few seconds as OS X would look for a functional startup disk.
Check and see if this works for you in bringing down boot times.
PS> Also check what login items you have in the lisr under Account.

Using new Extreme N in mixed environment, seems slower than plain old G...

I got a new Extreme N couple days ago. Installed it as the main base, with an older Airport Extreme and an Express as WDS stations.
My MacBook Pro does not have N hardware in it (grrrr, don't get me started . But my wife's MacBook does. I got the N because I really want a networked hard drive and figured we'll all have N at some point.
I understand that the network speed gets knocked down to G speed if there are non N clients on it. However, I swear it seems noticeably slower overall than my plain old G network.
Anyone else feeling like a mixed network is slower than plain G?
Also, does anyone have a sense for how security options impact peformance?
Thanks.
MacBook Pro Mac OS X (10.4.8)

I'm in a similar position, picking up the new AE this weekend, and form what I've read there's a better way, and here's what I'm going to do, maybe you'll want to try it:
-Setup the new AEx as an N-only network, ramped up.
-Connect either the older AEx or EXp via ethernet to it, and hang it off there in bridge mode.
-Try to put some distance between the two, at least 20 feet.
-You can set it up as a g-only network if you like, and it'll handle wireless communications from you, and the the other g base station, also offering it's services on your total network, but without decreasing the n-speed.
Hope it helps. For more info on setting this up, consult the 'Designing Airport Extreme-n Networks" manual, here (PDF).

New Mac Mini slower than my 4 years old iMac

My Intel iMac (20" display) four years old is out of order (I think the Power Supply was gone), and I bought the new entry level Mac Mini.
When I started using it I noticed that it's much slower in several tasks than my old iMac (when restarting, when opening applications, when working with an app with another appl in the background, etc. etc.). I was concerned about this, but then I asked some friends that have Mac minis and they said that it's normal.
Why? Why a computer with a new i5 Intel processor can be slower than a four years old iMac Core 2 Duo? Is it because of the slow drive (5200 rpm)? Or what is the explanation? If this is normal for the mini, I'll try to fix my old iMac as soon as possible.

Don't downgrade to Lion. For what it's worth, my experience with Lion and Mountain Lion has been almost the exact opposite than what CaptH reported: I find ML to be much faster and more reliable, both on my late-2012 Mini and my mid-2007 iMac.
Your perceived speed issues are almost certainly a result of the slower-spinning hard drive in the Mini as Shootist007 pointed out earlier. Go ahead and disable Spotlight if you want to, but once the indexing is complete (which can take a few hours – or even a few days if you have a lot of data) it shouldn't be a problem unless you are continually connecting different large external drives.
Get the latest Combo Updater and install that. If you have some minor OS issue, that should solve it. Do a normal Software Update / check the Mac App Store for updates after you install the Combo Updater. Get it here:
http://support.apple.com/kb/DL1640
If you continue to be bugged by the slower speed, see if your local Apple Store will allow you to exchange it and a little extra money for an equivalent model with a Fusion Drive. Or go to Other World Computing and purchase their kit to add a second drive, and use it to add an SSD in the second drive bay:
http://eshop.macsales.com/item/OWC/DIYIMM11D2/
http://eshop.macsales.com/search/OWC.INSTANT.481.2
Also, RAM is super-duper-uber-cheap right now. If your Mini has only the stock 4gb of RAM, you might be pleasantly surprised by the improved performance by doubling that. I have 16gb in my Mini, it cost me well less than a hundred bucks, and it makes everything better including graphics performance. But if you don't do something to work around that slow 5400rpm hard drive, it will always be the bottleneck in your system.
