What is an 'acceptable' Total Execution Time?

I think that an appropriate load time is one that doesn't make your customers say, "Nuts to this, its taking too long!" As stated above, if the content is worth a load time of 5 seconds, then 5 seconds is appropriate.

Depending on your content, you can use things like flush to start displaying data so the end user does not have to wait until the end of execution to see something.

What type of machine are you using? Are there other sites on that machine? What type of content are you delivering? 100ms is nothing if you are downloading 100MB video.
