Another Speed Test Result Question

I'm on Sky ADSL and consistently get the x6 results coming out significantly higher than the single thread result.

Looking back at my speed test history the x6 result has consistently been double the single thread test.

I have a few o2 results from before the handover to Sky and the difference was still marked although the single thread was more like two thirds the x6 result.

What is this telling me (other than I should have possibly migrated away from Sky some time ago)?

If you are a Windows XP user then the RWIN value may need tweaking, or you have a limitation locally due to wireless connectivity

On an iMac with a wired connection. Can run again of a Win8 laptop on a wired connection if that helps at all.

OK on Mac OSX when using Safari the flash socket protocol had a rate limit issue (page should have warned on this affecting tbbx1). So should not show up on flash version on other operating systems.

Or can force the non flash via http://labs.thinkbroadband.com/speedtest

Used Chrome for the test.

Tried the test of the laptop (on FF though):

And straight afterwards on the iMac.

Ran the non flash version on the iMac.

So not much variation between the flash and non-flash versions, but a stark difference to running it on the Win8 laptop.

So looks like Mac is the issue rather than the broadband connection then

Agreed.

Although not sure what tweaks I can do if any.

I'm still intrigued about whether other Mac users see a similar difference between the single and multi thread performance.

Is there anything that can be done on the Mac OS to improve the single thread performance?

We run a mixture of Windows/Mac OS devices ourselves and are not aware of any widespread issue with single thread performance on our Macs across various connections at various speeds.

The flash version has a legacy issue with the flash socket code has a 12 Mbps limit due to Safari flash, Chrome version does not have the issue.

Definitely using Chrome on the iMac.

I'd love to understand what the difference is. The iMAC is always slow compared to the Win8 laptop and switching the AV off seems to make little difference.

I did get one test where the two results were similar this afternoon, but testing again just now the Win8 test on FF is much better than the iMac on Chrome result.
