Re: Off-topic - Apache Config - Load crises
Your problem may be a network problem, not Apache/Mod_perl. Check with your upstream provider and have them do a bandwidth analysis. Here is why. I've strobed your network and the return time latency seems to be high. It would appear that you have about a 28 ms latency overhead in/out of your network. That is not a good sign. This is on top of what appears to be a standard 1.54 - 2.0 Mbps line. If your upstream feed is more than a T1 or E1 then you need to have a talk with your upstream. I suggest invest some time in bing. (bing not ping) Of course I'm looking at this through about 20 hops and because of that most of my information is inconclusive. I have noted that codix-pri-gw.uk.insnet.net, which appears to be an assigned router by your upstream, appears to be dropping packets. I get a 40% packet loss when I test to that address and beyond. Anyway, SWAG if this helps, good. If it did not help,... don't blame me, I'm not in the UK. Rafiq Ismail wrote: I know this is a bit off topic, but I could use some immediate advise on server config?

Should I: i) disable keep alive? ii) reduce the keep alive time out ? iii) up my number for max spare servers? Since i've not maxed out on load or memory, perhaps more idle servers will reduce the contention for apache children? My intutition is that since the server is obviously in trouble, resource wise, perhaps increasing the number of daemons will relieve the load. Not sure. It's a big box. Any ideas? iv) Something else?

Re: embperl
This will sould like sour grapes,. But! Since PHP module compiles,... and Mod_Perl will not on AIX with gcc compiler I'm thinkin' PHP is getting better and better all the time. iain truskett wrote: * Diego V ([EMAIL PROTECTED]) [07 Sep 2001 06:59]: [...] Just wanted to ask to any embperl user, is there any real advantage about using embperl instead of PHP ? You get the advantage of using Perl rather than PHP. This includes the vast resources of CPAN. Personally, I recommend Mason http://www.masonhq.com/ over Embperl simply because I prefer the way it integrates into HTML. Investigate both =) I've done reasonably sized projects with both and find Mason cleaner (mostly in its handling of scope and the way it doesn't use all those [- [+ [# [$ [* etc. tags and instead just has %, %init and other wordy ones: easier to remember =). ) cheers, -- iain. http://eh.org/~koschei/ The only disadvantage I see is that it would force everyone to get Perl.

Re: embperl
Well,... Now that makes some sense. I'll try that. Thanks. Jens-Uwe Mager wrote: On Mon, May 07, 2001 at 02:44:13AM -0500, Jim Cox wrote: This will sould like sour grapes,. But! Since PHP module compiles,... and Mod_Perl will not on AIX with gcc compiler As far as I have heard mod_perl will compile using gcc, only you must first compile your perl with gcc. As mod_perl picks up the compiler settings from the perl installation you must first compile perl with the proper compiler. But IBM does ship perl compiled using their compiler, so if you are lazy and do not recompile perl you are hosed. I'm not the lazy type, just did not realize that.

Mod_Perl on AIX
Can someone point me to the docs for compiling latest mod_perl 1.26 for apache 1.3.20 on AIX 4.3.3 using gcc. Or if docs don't exist, or if I missed something, Just slap me. The docs I've found result in a broken build enviromnent. I suspect that the problem is related to using gcc+ and not the distributed AIX cc. I just wanted to ask before I tried to modify the distributed Makefile.PL.

Re: Mod_Perl on AIX
Therein lies the problem. I currently do not have the IBM supplied cc on the system. If the answer is to use only the IBM cc I'm not sure there will be an answer. Everything else compiles fine, Apache, as well as the other modules. Thanks. Christian Gilmore wrote: It greatly depends upon how you built perl. If you're using the OS-provided perl installation, you'll have to use IBM C for AIX to compile apache/mod_perl. Also, other problems/pitfalls exist if you wish to use mod_perl as a DSO. These problems can be overcome, but you'll need specific versions to do so...
