We are currently pursuing a very encouraging approach of adding an optional 'lazy proc definition' capability, capitalizing on the 'unknown' processing of tcl. (Thanks to Jeff Hobbes for putting us on this path). Since most of our threads use a relatively small subset of all available procs, we hope to achieve significant performance and memory consumption wins by only loading procs in the interpeter that are actually needed.
More details to come early next week. -Elizabeth Dossy wrote: > On 2003.08.13, Elizabeth Thomas <[EMAIL PROTECTED]> wrote: > > We have a server that loads in a great deal of tcl - so much so that > the > > resulting init script is 6.6M in size and contains over 9900 procs. > > [...] > > > > 1.
