Summary: slow SFTP download speed

Initial Comment:
SFTP download speed slower in ~10 times then upload speed over SFTP in the same 
network conditions. As I am understood it is already known issue. Do you have 
patch or some workaround to increase SFTP download speed?

clarification: "Bane of Open Source" :-)  was not referring to this
project, it was a reference to the levels of "abandonware" that M$ loves to
crow about when claiming why they are "so much better".  Never mind that M$
routinely abandons any product it wants whenever it wants and with no
recourse whatsoever.

I have in fact encountered a number of "abandonware" projects in the open
source community.  For instance PHP itself has become a very big concern to
me.  Now I am very happy to see that they just recently released about 300
bug fixes for 5.2.9.  But if you look up the bugs on that list you will see
that many of them have been sitting idle for 2 years!!!  So finally after
no visible activity an amazing amount of activity.  But in those last two
years of no activity I've been getting concerned.

On the other hand, M$ has the attitude that if we shipped a bug before and
we didn't get x thousands of complaints about it, then no matter how bad
the bug is, it's okay to ship it again.  and oh by the way we also hid the
phone number were you are supposed to report those bugs...  (I have this
from an MS insider)   So yes, there is a difference between how open source
and M$ operate.   

But the open source model does not always work either, even though there
is the theoretical ability for anyone to fix a bug, as a practical matter
most people have neither the time nor the skill to fix these bugs and so if
the original developer community stops supporting a project is usually
disappears.  and thus the concern about abandonware.

okay, I accept that some problems are hard to fix.  And I am somewhat
reassured by your response, especially the speed of it.

But I will tell you that libssh2 for PHP has in fact caused me endless
grief with the many bugs it has.  And AFAIK it uses this library.  Now I've
been assuming that the problems I've been encountering are with the PECL
library itself and not with the underlying libssh2.   But after seeing this
bug report I started to wonder just where the real problem actually is.  

SSH2 for PHP is in insanely bad shape.  http://pecl.php.net/package/ssh2

Message:
People _are_ maintaining this package, but this particular problem requires
a re-design of how libssh2 currently works, more or less. In other words,
the performance problem is a bit tricky to solve and that is the reason it
is still not fixed. Other libssh2 problems are routinely being fixed, so
it's not the bane of open source projects just yet.

Message:
libssh2 is a very important and widely deployed library, especially by
PHP.

This sounds like a pretty important problem.  How come there isn't any one
maintaining this package?  Am I being naive/unreasonable?  Is this the bane
of open source that M$ loves to crow about?

it is known, but there's nobody working on it and there's no patch that I
know of.
