Slow shutdown - The console strikes back

I just found a comment in an earlier posting on this subject from Tyler (thanks Tyler!) that raised a good point. He was commenting on the difference he noticed in the shutdown speed after upgrading from 2GB of RAM to 4GB.

Now by default the "new" (all intel MBP's I believe) MBP's create a sleepimage file by default as they are set to hibernate instead of sleep, so you could draw a conclusion from this that a 4GB file would take longer to create than that of a 2GB file but this would only make sense if you were sleeping the MBP, not I would have thought, shutting it down.

It also doesnt explain why, on a fresh install of Leopard, that my MBP shuts down just as quickly with 4GB as with 2GB of RAM, which can only mean that its something I have done in terms of a program I have installed.

Tylers point made me think though if the "quality" of the RAM could factor into this equation as well? Then again, am I just over complicating this?

Blogging is back?

Blogging is back? Originally published on 17 JUL 2024 I haven’t had a blog for a long while now and truth be told, the ones that I have had in the past, never quite lasted very long. Part of the problem was always the amount of friction that it took to put together a blog post, coming up with an idea, finding the time to write it and edit it and so on. So why am I doing this now, again? It actually boils down to a YouTube video that I saw a couple of days ago now and what I believe was almost a throw away comment by the YouTuber about sharing information with your peers and having a record somewhere of what your thoughts were, what was happening at the time and so on. My plan here is mainly to talk about things that interest me, I know most people in general say that you need to pick a niche and stick to it, maybe it will come to that at some point but for now, I’m giving myself the freedom to write about what I want to. Hopefully this will mean that there is a chance that this bloggin...

Slow shutdown with Leopard - Possible Solution?

I was just playing around with this again and remembered that in the past, having external drives connected could cause the computer to shutdown slowly, one of the things that didnt occur to me until now though, was that my Windows Bootcamp partition may be an external drive of sorts, or at the least, may be affecting the shutdown cycle. So I ejected it and then tried shutting down. The computer now shuts off in 15 seconds or less as opposed to almost a minute before, it still doesnt seem as fast as a new install of Leopard but its definitely a big improvement. The question now though is why or what is it doing with the Windows partition before it shuts down? It also possibly invalidates the earlier line of research I was following with the menu applets, so clearly I need to look into this some more but its the first definite improvement I have seen. If you try this and it improves your shutdown speed please let me know, it will be interesting to compare.

Slow shutdown with Leopard and hibernate

Just for kicks yesterday, I reset my hibernatemode to 3 as I had previously set it to 0 as outlined in one of my posts below. Interestingly enough, my MBP now shuts down just as quickly as it did when I had hibernatemode set to 0 and thats also without having to eject my windows bootcamp partition. At the moment I have no idea why this is the case, I still have to check my log files but I thought I would share the info at least.
