SSD arriving tonight

I will install and let you know whether L4MAC is improved or not. FYI - My configuration is 2.93GH dual core MB Pro early 2009 17 inch with 8GB RAM and I only use L4 with iTunes and Word for Mac running which take little memory and my iTunes pulls from another drive as wel as my Word documents so there is no competition with the drive my Logos is loaded on.

Also wondering if 64 bit kernel being used ?

Wiki Slow Performance section => http://wiki.logos.com/Mac_Troubleshooting#Slow_Performance has link Enabling Snow Leopard 64 bit kernel noticeably faster, up to 30 %

Keep Smiling [:)]

Loaded SSD and running 64 bit...Logos 4 much improved, as well as the whole system.

Does Logos use 64 bit if you boot into it?

Does Logos use 64 bit if you boot into it?

Logos is a completely 32 bit program. No portion of Logos is yet coded for 64 bits. At least that is true in Windows. I imagine that it is also true for the Mac.

Logos 4 Mac is a 32-bit program. On a Mac capable of 64-bit addressing, switching Snow Leopard kernel from 32-bit to 64-bit noticeably improves performance for all applications (up to 30 %).

Most 3rd party programs are 32 bit at this point, but most programs and utilities that came with SL (10.6 OSX) were 64 bit, so often if you load into 64 bit, those programs run faster, as well as the background code.

This is a cruel analogy, but it is almost like when adding that extra 4GB of RAM, although I didn't often use more than 3GB, the additional "room" of RAM was like adding a better breathing unit on the machine; well I see 64 bit doing the same thing in terms of simultaneous processing power since although 32 bit programs won't utilize the benefits of 64 bit, there is an ancillary benefit of providing the additional breathing room.

We really do not realize how much the hard drive is used until you get an SSD and so many things are so much more responsive. There are a lot of programs which use the hard drive temporarily until they are closed down and the files written are deleted so you never see those accumulate on the drive, but the speed of the drive, nonetheless makes a difference while using the programs.

Just a thought.

64 bit apps will run on the 32 bit kernel on a 64 bit CPU. You can check this by going to Activity Monitor (found in Applications-> Utilities) and selecting all processes in the pop-up filter.

This will show you kind with Intel (64 bit) being 64 bit apps and just "Intel" being 32 bit apps. Your kernel is named kernal_task.

The kernel is the most fundamental part of any operating system. It is, in a way, sort of like the manager of a very complex factory. While this is a bit simplified, it is in charge of scheduling and regulating program access to the different parts of your computer (CPU, RAM, hard drive, network, etc) and handling communication between programs. No program gains access to any part of the computer without talking to the kernel first.

The kernel, just like any manager ;-), is all about managing, but doesn't get any real work done. The real work is done in the other programs on the system. Running the kernel in 64 bit mode allows the kernel to take advantage of the various 64bit enhancements and get its job done faster. The less time the kernel spends in the other program's way, the faster those programs can run.

The obvious question is, why didn't Apple run the kernel in 64bit mode by default? The 64bit kernel is pretty new and Apple needed to wait to let both it mature a bit and to allow third-party kernel extensions (such as drivers and parts of virtual machine software) to be released in 64 bit versions. More recent Macs, such as the late 2010 Mac Pro and the 2010 Mac Mini, come with 64 bit kernels enabled by default.
