proc timeprint {script} {
    return [lindex [uplevel [list time $script 1]] 0]
}

::itcl::class Book {
    public variable idnum
    public variable title foo
    public variable category bar
    public variable subcategory
    ...
}

set i 0
while {$i < 10000} {
    lappend cl [Book \#auto]
    incr i
}

foreach c $cl {
    puts [timeprint { set ttl [$c cget -title] }]
    puts [timeprint { set cat [$c cget -category] }]
}

Reports values like these:

100
93
101
92
100
93
100
93

Which seems ok. The problem is that for similar code in my program,
I'm getting much larger numbers:

374
364
369
389
372
364
366
427
381
367
368

and since I'm dealing with a lot of objects, this slows things down a
lot:-/ Any ideas on what could be causing this, or how to speed it up?
