 Hi,





 r311568 Set MORETOCOME for AIO write requests on a socket.

 After this commit freerdp is very slow.





 Before the password prompt would appear immediately when
 connecting to a server. Now it takes 5-10 seconds. After
 entering the password, another 5-10 seconds until I am
 connected. Once connected, there is a considerable lag.


 What could be the problem?

 kdump will generate a text representation, perhaps using 'kdump -s'
 to not include dumps of raw I/O data.  If you can put the output of
 kdump at a URL I can fetch from then I can look at it.

 Can you get a ktrace of the freerdp process during this?  The
 commit should only be setting MORETOCOME if multiple aio_write
 requests are queued to the same socket (so that TCP can batch them
 into a single packet). However, it should not affect an application
 just calling aio_write() on a socket once.

Can you get a ktrace of the freerdp process during this?  The commit
should only be setting MORETOCOME if multiple aio_write requests are
queued to the same socket (so that TCP can batch them into a single
packet).  However, it should not affect an application just calling
aio_write() on a socket once.

r311568 makes freerdp very slow

2017-01-12 Thread Jakob Alvermark 
Hi,

r311568 Set MORETOCOME for AIO write requests on a socket.

After this commit freerdp is very slow.

Before the password prompt would appear immediately when connecting to a
server. Now it takes 5-10 seconds. After entering the password, another
5-10 seconds until I am connected.
Once connected, there is a considerable lag.

What could be the problem?
