Optimizing the OS/WB

[smace]

Hello there!

I am interested in hearing about the sort of stuff that could slow down how workbench response to my actions. What makes it boot up slower, what makes windows pop up/draw slower? All in all, how can I optimize the OS' or WB's performance? Never been a 'techie', so any comments should be helpful
I've been thinking that the Amiga is an effective OS and all that and bla bla you know, but as more and more 'extras' like AHI and is it CyberGraphics library have become necessary I feel that even the good old A1200/060 have become too slow

Upgrading librarys, is that all there is too it?
I'm curious..

Yours, Per Arne

Thanks for all the response so far, people!

ARP commands, I have no idea what those are. I've never known what the addition of '> nil' to a command line does either  :-? Could you point me to a good documentation?
Is this AREXX or just basic system commands?
