OS Update

Filed under: Macintosh — jasony @ 11:54 pm

Apple released OS X update to 10.4.3. Against my normal operating procedure I went ahead and installed it only two days after the release. So far so good. The most dramatic change I noticed immediately was that my internet surfing sped up considerably. My measured bandwidth speed had been steadily decreasing over the last month or so. From a high of 1.4mbps so a recent low of only 200kbps. Today I even saw a download that clocked in around 60kbps! (but that may have been the server on the other end).

Regardless, I had thought that it was my ISP (COX). It never occurred to me that it might be the OS that was somehow causing the bottleneck.

Now, before you point out the obvious fact that bandwidth speed is a constant incoming pipe and the OS should have no effect on it at all, I agree with you. I just cannot see how an independent test (here) could be altered by my OS. I’m just reporting what I’ve observed. Despite numerous restarts, permission checks, and other OS tricks I’ve learned, my download speeds were slowly getting measurably worse over the last few months (I have the data in a spreadsheet). When I installed the 10.4.3 update I immediately got dramatically faster speeds, on the order of 1.8mbps. I haven’t seen that speed since, now that I think about it, before I installed Tiger (X.4). Coincidence? Maybe, but it seems unlikely to me.

Anyone have an explanation, I’d appreciate an email. Until then I won’t complain.

(just checked and my speed is 1.2mbps… still not the “up to 4mbps” that Cox infers, but I’ll take it)
