Filipe Manana commented on COUCHDB-743:
---------------------------------------

You sure it's a CouchDB problem?

I'm with the latest trunk version and for a file of size 2,2 Kbs, it takes 0.02 
seconds the upload:

$ time --format=%e curl -X PUT 
http://localhost:5984/testedb/doc1/readme.txt?rev=1-17907786cd284d6585a640e97e0ff8b6
 --data-binary @/home/fdmanana/git/couchdb/README -H 'Content-Type: text/plain'
{"ok":true,"id":"doc1","rev":"2-14094b637bf02c3052b9a9a04f0750ff"}

>             Project: CouchDB
>          Issue Type: Bug
>          Components: Database Core, HTTP Interface
>    Affects Versions: 0.10, 0.10.1
>         Environment: Ubuntu Karmic (9.10) with CouchDB 0.10.0. According to 
> IRC conversations, also reproduced with 0.10.1
>            Reporter: Jyrki Pulliainen

> When using HTTP PUT to store attachments the request takes exactly one second 
> to finish when the attachment size is 1025 bytes or more. This behaviour does 
> not occur with inline attachments.
> Here's a bash script to reproduce the behaviour (requires curl and python >= 
> 2.6)
> #!/bin/sh
> size=1025
> curl -X DELETE http://localhost:5984/test
> curl -X PUT http://localhost:5984/test
> docid=0
> while true; do
>     rev=`curl -s -X PUT http://localhost:5984/test/$docid --data-binary '{}' 
> | python -c "import json; import sys; print json.load(sys.stdin)['rev']"`
>     echo -n "start:"; date '+%H:%M:%S.%N'
>     head -c $size /dev/urandom | curl -s -X PUT -H 'Content-Type: text/plain' 
> http://localhost:5984/test/$docid/attachment\?rev=$rev --data-binary @-
>     echo -n "end:"; date '+%H:%M:%S.%N'
>     docid=$(($docid+1))
> done
