I have roughly 3.81 GB to download as I'm installing the program for the first time. It's downloaded roughly 10% in around 30 mins or so. Given that I'm using a 50MB connection, speed isn't the issue. I'm downloading everything else (at other times, of course) at pretty much the full speed that my bandwidth allows.

Any clues as to why everything is downloading so slow?

Christopher - 

First, welcome to the forums!

The Mac version always seems to have problems with downloads… It may be that the percentage indicator isn't reflecting appropriately. Also, there may be a slowdown on the server hosting Logos.

Most of my downloads have been pretty fast, so I'm incline to believe it's a temporary server issue.

I concur - I reread my post and it sounded like I thought the Mac "always had problems." What I meant was the indexing indicator… another issue altogether. Embarrassed

Welcome Big Smile

Curious what network transfer speed is showing in Apple's Activity Monitor ?  Also wondering if transfer rate is going up and down ? (or steady ?)

By the way, am a bit curious about a 50 MB connection ? (e.g. DS 3 or OC 1 ?)

 Wikipedia article => https://en.wikipedia.org/wiki/Optical_Carrier shows OC 1 is 51.84 Mbit/sec while article => https://en.wikipedia.org/wiki/T-carrier shows DS 3 is 44.736 Mbit/sec

Observation: data transfer of 381 MB in 30 minutes is an effective average of 1.69 Mbit/sec that is closer to DS 1 (T 1) speed, which could appear as 211 KB/sec in Apple's Activity Monitor (for steady transfer).

Similar thread => Is there a download bandwidth service level agreement with Amazon S3?

My guess is he really has a 50mb (megabit) connection, which is 50,000 kbps (kilobits per second).  Our local provider offers 20, 25, and 50mb connections over fiber direct to the premises (I have the 20 down, 2 up).  Generally the nomenclature is to use lower case for internet / network speeds in megabits, and uppercase for megabytes, usually measuring amount of memory or hard drive space, etc.  So for example if your Ethernet port on your computer is a "Gigabit" connection its speed is 1gb per second, or 1000mb per second, but not to be confused with 1GB (or 1000 MB or megabytes) like we measure hard drives (and yes I know it is really multiples of 1024 because it is binary and such but I am rounding for simplification).  Sometimes (as in KS4J's example) people use an uppercase K or M but then lowercase b or bit to differentiate also.

 

Be Blessed

50 mega bit per second should equate to 51,200 kilobits per second, which is 6,400 kilobytes per second or 6.25 MegaBytes per second.

To transfer 3.81 GigaBytes at 6.25 MegaBytes per second needs more than 624 seconds (since transfer also includes overhead, including connection handshaking for each file).   The Original Languages library has 3.81 GB to download with over 300 resource files.  Without network congestion, guessing ~ 15 minutes to download if all network equipment between computer and Amazon S3 servers are capable of 50 megabit per second connection speed.  Somewhere along network path(s) to Amazon's S3 servers, wondering about significant congestion (or network bottleneck or bandwidth throttling) since 10 % of 3.81 GB was downloaded in 30 minutes.
