Hi, I've been trying to stress the system a bit and i've come up against some issues, if anyone can shed light on them that'd be great... I patched my local to add errno via sb-alien:get-errno, but couldn't find a decent portable solution. ---------------------------------------- case 1 Using /usr/sbin/ab2 -n 500000 -c 1000 http://localhost:16323/ Completed 300000 requests apr_recv: Connection timed out (110) Total of 312165 requests completed meanwhile theres not a peep from the server Starting server on "127.0.0.1" port 16323..

Here's an asd file for nio-httpd. Just to make things a little easier on the end user... nio-httpd.asd: ;;;; -*- Mode: LISP; Syntax: ANSI-Common-Lisp; Base: 10 -*- (defsystem :nio-httpd :components ((:file "nio-server") (:file "nio-httpd" :depends-on ("nio-server"))) :depends-on (:nio)) Cheers, Bill. -- William Bland: http://www.abstractnonsense.org/ Lisp documentation: http://www.lispdoc.com/

[nio-devel] NIO is asdf-installable
by William Bland 03 Oct '06

03 Oct '06

Hi, I just made NIO asdf-installable. The only change I made to what's in the current code was: Index: nio.asd =================================================================== --- nio.asd (revision 3) +++ nio.asd (working copy) @@ -9,5 +9,5 @@ (:file "async-socket" :depends-on ("async-fd")) ) - :depends-on (:cffi)) + :depends-on (:cffi :event-notification)) Hope that looks ok to you. If not, just let me know and I'll change it. Cheers, Bill. -- William Bland: http://www.abstractnonsense.org/ Lisp documentation: http://www.lispdoc.com/
