OS X :: Big Difference Between Speed Test & File Downloads - Finding Explanation
May 1, 2009
i have a 1.5 Mbps AT&T DSL connection, and multiple speed tests show a download speed of 1.2 Mbps (and 200 Kbps upload). when i download files, such as software updates from Apple, various podcasts, and even Silverlight from Microshaft, the speed is always between 140 - 160 Kbps. i contacted AT&T, and the rep said it was because of buffering by the servers i was receiving the files from.

I'm wondering if someone with the latest Time Capsule (announced last week) can post the results of copying a large file (such as your iPhoto library or equivalent - ideally over 500MB) from the HD on your Mac to the HD on the TC over GigE.
Please report the time in seconds for the copy to complete and the size of the file. I'd like to understand if they changed the QoS on transfers to the TC HD.

Sorry for the title but I couldn't think of anything better. Hopefully I'll be able to explain my problem. I have a MPR 2.53 ghz, 4 gig ram, I'm using Safari 4.04. I am using the WIFI at a guesthouse in Thailand (but I had the same issue in China, Vietnam ...). I ran a speed test and it said download 7mb/sec and upload about 1mb/sec. I have an "app" that says bandwidth in 1.3kb/sec out 1.0kbs. I thought maybe it was Safari so I downloaded and installed Firefox. firefox gives me similar speeds. When I downloaded Firefox though I had a download speed of over 1mb/sec. But as soon as it finished downloading the speed went back to around 1kb/sec. I have rebooted my MBP many times. I did some Google searches but didn't find anything helpful.

Recently I bought WD6400AAKS hard drive. I made to partitions (1st for OS and applications, 2nd one for photo files). I also did fresh OS install and loaded basic applications. Strangely I didn't notice any speed boost while booting and to be honest I feel like all applications (photoshop for example) are also starting much slower than on original hdd. Is there any way to test hard drive if it performs as it should be? I also have 2 more older drives installed. is it possible that one of them would slow the system down?

around my house, even right next to my wireless router, I have a pretty slow WiFi speed - normally my downloads are under 20kbs a second (I have a hard time even watching YouTube videos). When I plug my laptop into an ethernet port, it greatly increases and I sometimes see speeds above 100kbs. I'm using a really cheap router, but I've used other routers with the same results.

I'm trying to decide whether to buy the express or the extreme.
I will only be using it for web surfing with my macbook pro.
But in the near future I might buy a wifi skype phone (which is g).
If I'm using the express, that means my macbook pro connection will change from n to g (because it is not simultaneous as in the extreme) when the wifi phone connects.
Will shifting from n to g change drastically my internet speeds in my macbook pro?
If my download speed is 300 Kb/s and my upload is 30 Kb/s with "n"; how much will that change when shifting to "g"?

I would like to direct my Documents, Pictures, and "Other" to 3 folders in my downloads folder upon downloading them, either with Safari, with Finder, Folder Actions, Automator, or with any other free tool that does not take up too much CPU load.Â

How much speed difference is there? Battery I take it is almost double in real life, actually using the MBA. I get barely 3 hours with moderate use on my Rev B and I take it most people get close to 7 with similar usage?

Just wondering what the speed difference would be if i upgraded from 5400 to 7200 RPM? Is it worth it or perhaps is an external drive the way to go?

I know this topic has been gone over several times, but I'm still having trouble deciding on which to get in a new 15", 2.8Ghz MBP - 5400/500GB, or 7200rpm/320GB (or 500, really). I'll be using the machine largely for graphic design, but also for various other tasks as my main computer. I've heard the faster drive IS a noticeable difference, but it also drains battery life and runs hot. There doesn't seem to be a consensus on this anywhere. Is the 7200 worth it?

Is it worth the extra cash to go up to the 2.13? I know it's a small amount, but that could be a new mouse, or a super drive. I've seen tests that indicate the rev b 1.86 is actually faster than the new 2.13. This will be my only personal mac. I'm a graphic designer (adobe cs4) but I don't do much design work on my personal computer (I have a nice iMac at work). The usual facebook, email, web browsing, YouTube

I'm looking to replace my current external drive with a newer, larger drive. My current drive is connected via Firewire and houses my iTunes library, plus movie files, documents, etc. I'm trying to decide between a portable drive (the Western Digital Passport, for example), and another desktop drive (like say, this one [URL:..]Questions I have:
- Is there any reason to be concerned about longevity when using a portable drive?
- Does a desktop drive typically perform better than a desktop drive?
- Is there a noticeable speed difference between USB 2.0 and Firewire?

Awhile back I was messing with some things and now...the atypical/stock downloads icon that sits on the dock got deleted. I tried dragging and dropping the downloads folder there, but that has other downloads info.
I just want that little 2/3"x2/3" (not sure on actual size) window that pops up as you are downloading something. It still pops up when I am downloading, but it isn't on the dock.

I'm looking at second hand 2009 quad mac pros. I'm not sure if 2.66 has a massive disadvantage over the 2.93. The thing is, I'm buying this for quite a long run (I work with audio/ Logic pro). I'm thinking that the 2.93 will be more future proof? Does anyone have any experience with the two?

For almost the last year I have been using an Airport Extreme on 2.4b/g and and Airport express in my room to extend my wireless network. I also have a usb hdd configured to back up my macbook using time machine. Well I have a new roommate moving in and he has his own extreme and two expresses.
I have some questions on what would be the best way to consolidate our networking devices. I considered us selling our extremes and getting the new time capsule so both of our macs can use 5ghz while my girlfriends dell uses the 2.4.
Is there a noticeable speed difference between time capsule backup vs hard drive to extreme connected via usb?

I'm new to Mac so please be gentle!
I've just added a couple of entries to my HOSTS file to test whether it works the same way in Mac OSX (SL) as it does in Windoze.
I've found it does... and it doesn't.
My 4 test entries are totally blocked if I use Safari, but they're NOT blocked in Firefox.
Could someone tell me in simple terms why this is so, and if there's something I can do to make Firefox obey the HOSTS redirects?
