Summary: Slow file transfers
Product: Apache httpd-2
Version: 2.2.8
Platform: PC
URL: http://beta.inthecrack.com
OS/Version: Windows Server 2003
Status: NEW
Severity: major
Priority: P2
Component: All
AssignedTo: bugs@httpd.apache.org
ReportedBy: apache@codeinfusion.com
Moving out site onto a new Windows 2003 server, same Apache config, static
file downloads are limited to 350-600Kb/sec. The new server is on a gigE
connection. The previous server gave us 2MB/sec download. Both are similar
hardware - Dell 2950/1950 with 4GB RAM and dual quad-core xeon. Both on same
OS.
Install of IIS maxes out bandwidth of the visitor's connection - I've seen
2.5MB/sec.
FTP maxes out connection, even when testing on port 80.
Since IIS & FileZilla FTP both max out the connection and Apache is 1/6 the
speed, I'm assumming there is an incompatiblity somewhere. I reinstalled both
2.2.8 and 2.2.6 without SSL, vanilla and wiped out the httpd.conf - but no
better.

EnableSendfile Off speeds up static file transfers from about 350Kb/sec to
750Kb/sec. No other setting helps.
PHP streaming transfers max out the visitor's connection speed - for me it is
about 2MB/sec.

another thing to try
SendBufferSize 10000000
(number is probably overkill, but sufficient for testing the theory; I saw a
complaint recently that Apache on Windows was using much smaller TCP windows
than IIS; I don't think "ReceiveBufferSize 10000000" would help here)

I tried all of the tricks suggested with no significant success. I did notice
that EnableSendfile off did double my download speeds to 700Kb/sec, but
unfortunately, the other options didn't make a difference. I had great hope
for the ReceiveBufferSize, but it seems that my Window Size is sufficent.

Just to verify...
You did confirm that EnableSendfile Off speeds things up? Does EnableMMAP Off
further change the performance for better or worse?

I've noticed that file download sent via PHP "streaming" using the PEAR
HTTP_Download package are sending at full speed. Just static content is
slowed.

This is a question that should be tried first on a user-support forum like the
users@httpd.apache.org mailing list before filing a bug report.
(Before you post to the users list, try the standard win32 trick:
EnableSendfile off
EnableMMAP off
Win32DiableAcceptEx
)

EnableMMAP Off had no noticable effect.
