Under my Window 7 64-bit OS, I've installed both Nightly Build v28 and v29 to perform "internet speed test" and each time, I can only achieve something < 2 mbps for my home Wi-Fi, gateway router which is about >56 Mbps. The only working Nightly version was v23 that could achieve close to >52 mbps. But once I update v23 to higher version, all the normal high speeds I could achieve at Nightly v23 are gone. The same issue plagued also firefox v26 under Win 7 64-bit.

For clarification, this is not true under Win 7 32-bit OS - the same firefox v26 works fine to achieve the raw BW speed close to and >56 mbps. WHy not in 64-bit OS seems to be the main question?

What's going on? I greatly appreciate you looking into and helping me out on this dilemma. Thanks!

Sincerely Shao Ma

hello Shao Ma, when you are using speedtest.net or a similar flash-based site to measure your connection speed then it might be an issue with the protected mode that adobe has introduced for its flash plugin for firefox. some old versions of f-secure or trusteer rapport are known to cause such slowdowns together with flash, or it might be something similar on your system that is interfering (maybe security software that is blocking/sandboxing the container used for the protected mode, etc...).

as a workaround you could try disabling protected mode & see if this makes a difference.

in case you'd like to troubleshoot the issue further, it would be best to contact adobe's support & file a bug report at bugbase.adobe.com (choose "Adobe Flash Player" as the product & "Browser Integration" as the product area), since they will have a better understanding of the internals of flash protected mode & therefore may know what else might be at the root of the problem you were seeing.
