Hey Mike, I was wondering if you might explain a little on exactly what each software used for performance does for your system, what OS you use the software for and where to download each one. I found the TLSFmem no problem and I think the Thor MMU libraries on AmiNet but not sure if they are the latest versions. Couldn't find what may be the latest version of workbench.library or Env-Handler. What exactly do you notice that improves system performance from TLSFmem? What does the MMU libraries do and would it interfere if using ACATune with one of Jens' accelerators? Also, what does a newer workbench.library and Env-Handler do? I always worry about installing things like this due to dependencies and backing them out if something goes wrong. I did unpack and run from a command line the TLSFmem and got no error so I assume it ran ok resident... what should I expect to happen? 
Aah, that's a lot of questions! The TLSFmem prevents memory fragmentation. It does a great job of it, by putting it very early in your S-S it allocates as much of your memory as possible and manages it all in one big chunk. That chunk takes a higher priority than any memory it wasn't able to allocate, so it will be used first. You can check all this with SysInfo. The latest version AFAIK is 1.9. I downloaded an earlier version (1.6, if I recall) and then installed the 1.9 update with spatch from the author's website. In other words, it was a pain! Send me your email address and I'll send you a copy.
So it doesn't really "speed up" your system, but in terms of performance it manages your memory soooo much better than the native system functions.
The Thor MMU libraries are on Aminet. They offload a lot of system functions to the MMU for more efficient operation. Normally the MMU in an Amiga isn't used for much. This changes that. I installed these libraries and a few of the other utilities in the package, and noticed a definite speed-up in many system functions. Obviously these only work if you have a system with an MMU, preferably an 040 or better. I don't think they will work with any of Jens' accelerators (do they have an MMU?).
Workbench.library is part of Peter K's icon.library package. To install it you have to use spatch on a copy of a Kickstart ROM (to extract the original workbench.library), which is then patched, and the new file is then soft-kicked during the boot process. With 3.1 you have to use LoadModule, 3.9 will load it automatically. It adds a bunch of new Workbench menu items and general performance improvements (since the workbench.library in our ROM's is at best 20 years old, LOL).
Env-Handler is here:
http://aminet.net/package/util/sys/envhandlerIt eliminates the need to load the entire contents of your Envarc: directory into Env: at each bootup, only loading things as they're needed. Saves memory, gives faster boot time. Win-win.
Always make a backup of your Startup-Sequence and User-Startup before making any changes, but otherwise these programs are safe.
Does that answer everything? 'cause I need to get out of here! Need to get some sleep... or some coffee, LOL. :pint:
PS - did you see my response in the other thread about the AD516? It rocks!
