To be clear, I wasn't referring at all to anything about you or setup Derrick. :-) Still, as you're saying, yes there are also those kinds of issues that can cause problems as well. Good that you've isolated a lot of them.
That said, as for your moving to BD, I will argue that when some have asserted that only another CFML engine was capable of handling their load, I always wonder if their problem with CF was really what it appeared to be on the surface. In fact, someone could install a new engine on the same machine talking to the same DB with the same load as CF did, and argue that it was better, and I would be willing to bet that a new install of CF could also have had the same improvement. Again, too much to get into in this thread, but I can attest to the situations. So I'm not knocking the other engines. I'm just saying that sometimes the moves to them (or off of CFML to some other platform) could have maybe been avoided by just getting to the root cause of the problems. There are nearly always discernable explanations, if one knows where to look and how to connect the dots. And to be clear, there are indeed many here who can and do just that, so I'm not saying I'm a superhero. I'm just saying that in addition to 12 years with CF and 25 in IT, I've also focused the past 3 solely on CF server troubleshooting, and I've learned an awful lot. I've had the benefit of learning from many here on this list. More than that, I've been able to make it my day's work each day to focus on this stuff, so it's a unique blessing. I realize why most can't do this in their day. All I'm saying is that I want to help people be more effective in their trying to understand and resolve CF (or other CFML engine) problems. The problems (and solutions) are not always what they seem on the surface. :-) The good news is that there is a lot of info out there, it's just a matter of finding the right info for the right problem-and synthesizing it. I'll do what I can in coming years to help with that (the radio show, a planned wiki, and more). /charlie From: ad...@acfug.org [mailto:ad...@acfug.org] On Behalf Of Derrick Peavy Sent: Thursday, January 14, 2010 7:39 PM To: discussion@acfug.org Subject: Re: [ACFUG Discuss] Ideal memory & Configuration for CF Production server? Charlie: I have seen those errors before and would in the past, adjust both java Vm settings and heap size in the BD admin console, as well as MySQL settings. I did that over many months a few years back. Using the same system today. The settings I use now yielded the best results - no errors, faster execution times, no crashes, low cpu usage. However.... I do agree with you that there are often many other issues to solve. In fact, thinking back to our meeting back in 2004 when you helped me set up BD on my XServe and thus made me a BD fan forever, it was obvious then that there were other issues to solve and that BD/CF was not the issue. Over the past 5 years, BD 6 has proven to be very reliable and robust and I generate a fair number of page views on a daily basis. Yesterday, for example, 79,000 CF pages generated - granted 72,000 were spider/crawlers and only 7,000 were user page views. But as far as the data execution, a page load is a page load. And that does not include the 10,000 RSS feeds generated on the fly. So... When I've run into problems in the past, it's generally been either an SQL statement that I did not think through, or a server issue - mail problems, FTP break in attempt, etc., All that being said, over the pst 5 years, we've taken pains to simplify the roles of the server itself so that it is not doing 100 various things. DNS, a single mail account, a very few select number of FTP users, firewall and then web. That's it. No custom install stuff, very strict clean OS. And with that, the settings I have used for BD (CF) remain the best for my situation. 4 GB to MySQL, 2 GB to BD w/1GB heap. I say "best" because I sleep at night and don't have errors, excessive CPU or other crazy issues. Perhaps someone could tweak it more. But it's a proven set up. _____________________ Derrick Peavy ------------------------------------------------------------- To unsubscribe from this list, manage your profile @ http://www.acfug.org?fa=login.edituserform For more info, see http://www.acfug.org/mailinglists Archive @ http://www.mail-archive.com/discussion%40acfug.org/ List hosted by http://www.fusionlink.com -------------------------------------------------------------
