Hi I'm having some issues with the speed at which a Solaris 10 system
running Apache 2 that came with the standard distribution.  This is on a
V210 server.  It seems like the max bandwidth is about 250 KBps on transfers
of large files.  SSH seems to have the same issue where there is a max
speed.

The strange this is when I use FTP I'm getting 5 Mbps most of the time and
outbound connections from the server to get updates are also very fast.  So
I'm wondering if there is a solaris package that is possibly capping the
speed of certain TCP traffic and ports?

If anyone could recommend things to try next that would be great.  I've
tried using the packaged Apache 1 instead with no difference, tried the CSW
pkg-get version of Apache2 on a different port but no luck there.

Regards,
Robert

First thing I'd suggest is to evaluate your need for Apache 2.0.x since 
Apache 2.2.x is out and supports large files (and more), in addition to 
the Sun Java System Web Server 6 or 7 preview.

I've had very good performance and no problems with SJSWS 7 preview and 
Apache 2.2.x finally supports large files (>2Gb).

However, running the included Apache 2.0.x or 1.3.x as you suggest is 
easier to install/start since it's bundled.

Is it when you transfer files with HTTP ?

There is no such package.

So you have problem with outbound loads but not with inbound loads?

Check for a duplex mismatch; is the switched forced to 100/full?  This
would explain the assymetry in the behaviour.

Hi Wes,

Thanks for the information on Apache 2.2.  I've just installed it from the
CSW package.  It seems to be getting 165 KBps after about 4 minutes into a
transfer.  So it would appear to be suffering from the same problem as
whatever is making Apache 2.0 slow.

I haven't tried Sun's own web server package yet, I wonder is that Apache
with some addons or a completely different package?

Thanks.

Hi again,

Thankyou everyone for all the useful comments.  I found the stuff about
Sun's web server package interesting, we will certainly investigate using
that and try and compare the speed and support for perl/php scripts etc.

I think I've finally found the problem, it would appear to be the internal
network.  I've come in through a different network and I can get connections
to our webservers at 1.6 MBps.  Still maybe we can fine tune things to
improve the speed even further.

Regards,
Bob
