Performance

[EngR H <h_...@yahoo.com>]

Hello Again!
 
Am working with WCK, customized it to work on my DMS, the problem is that the performance is too slow! when i tried to debug and see which methods takes much time, I found that alot of methods are called twice, and don't know why, for example giving the uri of /files the following methods are called twice before going to the next level:  
getChildrenNames()
readProperties()
getLastModified()
getLastModified()
 
Is there any thing that should be adjusted?? or is that the normal behaviour of the WebdavServlet??
 
any suggestions??
 
Regards
rony

I am seeing this also (see my previous post).

We can deal with Very Large Objects in our archive, and the hard-coded 2k buffer size in org/apache/slide/webdav/method/GetMethod.java was killing read performance. Getting a single chunk of data from our archive is a bit expensive, so I implemented a better buffering scheme (with a still hard-coded limit). Unified diff is attached.

On my local machine, I went from ~115KB/sec reads to ~9MB/sec reads for large objects.

If someone with commit privs would review, I would appreciate it.

Thanks
-John
