Version 3 of The Slow

Updated 2009-03-17 08:14:32 by jdc

jdc 16-mar-2009] At times the wiki becomes slow. This can be reconstructed offline using the scripts at http://jos.decoster.googlepages.com/ex_slow.tar.gz

What you'll need:

After unpacking the ex_slow.tar.gz archive you may have to adjust the auto_path's.

first you'll nee to start the webserver. Go to the ex_slow directory and run the following command:

 tclsh ex.tcl

To see the sloweness, I run this command 4 times in parallel from the tests_slow directory:

 tclsh get.tcl

and from that same directory I also run:

 tclsh aget.tcl

When the aget.tcl script completes, one or more of the get.tcl scripts stall.

LV So, does it appear that the performance hit is occurring in the wub coding, or in the tcl interpreter? jdc 17-mar-2009 There was a race condition in Wub, and Wub moved to event-driven output. Using the latest version of Wub from svn no longer has the problem.
