Hi!

If I send a certain amount of bytes (20344), it takes .3 seconds. But if I send one that's just a single byte bigger than that, it takes over 5 seconds.

Aside from that unexpected jump, it otherwise looks linear with the number of bytes sent.

I hunted down the problem, and discovered that if I slept for .1 seconds before drakma:HTTP-REQUEST calls FINISH-OUTPUT, the problem goes away. (Until, I suppose, I send something much bigger.)

Any ideas? Maybe this is a Lispworks problem?

(Lispworks 5.0.0, WinXP, Drakma 0.11.5)

Thanks, Tayssir

PS: My test --

cl-user> (let* ((num-octets 20345) (octets (coerce (loop repeat num-octets collect (code-char 50)) 'vector))) (time (drakma:http-request "http://..." :content-length num-octets :content-type "application/octet-stream" :want-stream nil :method :post :content octets)))

User time = 0.000 System time = 0.010 Elapsed time = 5.225 Allocation = 37612 bytes
