Subject [users@httpd] Apache 2 slow response to LanDesk Downloader
Date Tue, 07 Jul 2009 10:14:54 GMT
I've an Apache2 serving as "file server" for LanDesk Management
I'm having trouble with Apache when used by LanDesk client because of
such a strange
behaviour: the client makes tons of small requests for downloading a
big file and the server, even if unloaded, respond too slow. The
single request is served fast but the seems to arrive slower, as they
were enqueued.
For instance, let say my client wants to downlaod a 200Mbytes file
It'll make a lot of ~10kbytes requests (10 about concurrent).

MaxClients is never reached, cpu uptime is ~0 and there's enough free
memory, iptables is disabled, network connection is ok (a single
download is made at 11Mbytes/sec about), no rewrite or dynamic page
occurs (all unneeded modules have been disabled).

I've tryed lighttpd and works fine.

I'm running Apache 2.2.3 (tested with both worker and prefork mode) on
rhel 5.

Is there any strange protection against dos or parameters to slow down
concurrent request from the same client?

thx in advance,
