[MacTUG] Leopard detrimental to network speed?

[Marlon A. Griffith]

Some users are experiencing less-than-satisfactory network performance since their upgrade to Mac OS X 10.5 Leopard, or from the 10.5.1 update, and are seeking help on Apple's forums (1 | 2 | 3 | 4). The reports vary in circumstance, with some users having troubles on third-party network equipment while others that use the same hardware deny having any issues. Most of the complaints revolve around poor network reception, low speed, and a high ping rate – a type of network command that displays network latency in milliseconds. Most users with the problem seem to believe that it is a problem related to DNS entries, and some are turning to DNS hosting services such as OpenDNS.com.

Although the complaints are revolving around the same event (upgrading to Leopard), as previously mentioned, not everyone is experiencing the issue. There does not seem to be any common factors, as some have the issue when wireless, but not when connected directly to their router, while some experience problems with both.

Apple has not commented on the matter in any official regard despite numerous complaints from users.
