Patsy I run something similar here in Greece, but have not noticed any performance problems just yet. You are probably getting a lot of hits! What you need is an apache module designed specifically for speed / bandwidth throttling: www/mod_cband You may also wish to have a look at these instructions (linux specific, but easy to adjust for FreeBSD): http://howtoforge.com/mod_cband_apache2_bandwidth_quota_throttling BTW, what is your ADSL speed? You mention upload capacity of 500kb/s, and I suppose you mean kbits/sec, *not* kbytes/sec. Assuming it is kbits, you may well be consuming all your upload bandwidth if for some reason you get more than a few simultaneous connections... My estimated upload speed is 500kilobits per second. mod_cband seems to do the trick perfectly. I set maximum global upload to 400kilobits per second and all seems to be working well. Just as a side note for anyone S'ing the FA's, when I ran: #pkg_add -r mod_cband it pulled down a version of mod_cband compiled for Apache 2.0, with Apache 2.0 therefore being a dependancy, it was pulled down as well. After I removed 2.0, I needed to reinstall 2.2 and make mod_cband from ports. None of this was a problem, I just thought it should be on the list somewhere. Many thanks to everybody who responded.

If you pull packages from FreeBSD servers, then you should expect them to use default options (more to the point, the options defined by PACKAGE_BUILDING if the port specifies it) and default dependencies. The default APACHE_PORT is www/apache20. If you use www/apache22, then you 'cannot' use those packages. -- Mel Problem with today's modular software: they start with the modules and never get to the software part. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Limiting apache's upload speed?
Hello list, I am running FreeBSD 7.0-RELEASE (GENERIC), I am running Apache 2.2.6_2 and hosting a small website with a few relatively small (500kB-900kB) photographs. I am doing so from a home ADSL connection in the UK and so I am estimating my upload capacity at 500kb/s. When I have apache enabled and serving the web page it seems to disrupt my other network programs - on my main computer (running Debian etch) Wengophone stutters and my browser slows down noticeably. When apache is disabled these problems disappear. I do not wish to take my website down and so I was hoping somebody would be able to tell me if it is possible to throttle apache's upload speed. It seems that this would provide a good solution - people will need to wait a little longer to see my page, but a change of waiting 3 seconds to waiting 6 seconds isn't terrible.

My router does not appear to have the option to throttle individual hosts/ports. Any advice on the matter would be appreciated. I would suggest you look into PF + ALTQ. ALTQ is a rule based bandwidth control for PF which would allow you to adjust how much bandwidth you allow on the port 80. You will need to enable ALTQ in your kernel as it does not come enabled by default. See pf.conf(5) and altq(4)for more details.

When apache is disabled these problems disappear. Like Manolis I suspect your outbound bandwidth is often being saturated serving images. Unless you leave yourself enough outbound bandwidth for snappy delivery of requests and acks for inbound sessions, performance suffers tragically. Bandwidth limiting apache to maybe 400kbit/s should leave you plenty of headroom (unless you're uploading torrents too :) I do not wish to take my website down and so I was hoping somebody would be able to tell me if it is possible to throttle apache's upload speed.

My router does not appear to have the option to throttle individual hosts/ports. Any advice on the matter would be appreciated. The apache module should do that job. For a more generic solution (and perhaps anyway, given some crazed robots will suck down your whole site xty times a day, if allowed) a firewall with pipe/queue management, like Jeff's pf+altq, or ipfw+dummynet, can provide more fine-grained control. cheers, Ian ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: Limiting apache's upload speed?
My router does not appear to have the option to throttle individual hosts/ports. Any advice on the matter would be appreciated. best option is to use ipfw to manage outbound traffic, with fair sharing of bandwidth (possibly giving ack's higher weight, or specially giving lower weight to apache outgoing traffic). set up bandwidth to something below your operator's declared. like 450kbit/s or less. ADSL modems (at least this used by polish telecom) tend to choke when upload bandwidth is near max. delays gets even above 1000ms ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
