OK, that is all I wanted to hear regarding SM. Thanks

Removing subscriptions manager from IPB is like shooting yourself into your own leg. You are getting money which our customers pay us via subscriptions manager.

I'm also dealing with smaller companies that is why I said that. And regarding big companies NV, AMD and some other gpu providers are reading site and they are up to date with their browsers.

True, but like you said IE7, if we talked about IE7 that would be a problem, but we are talking here about IE6 which is EOL like PHP 4.x. So any business would decide to upgrade to even IE7 if not IE8 because old version of IE poses security risk for their business. Anyway it not that big deal, people adopt fast if they cannot use full functionality of certain hardware and in this case they need to spend 5-15mins of their life to upgrade to newer IE or alternative browser. And of course if company allows windows update, M$ will enforce upgrading of IE (probably marking IE update as critical) so those users will be up to date.

They said it will be supported, maybe not anything but most functions. If you can check my stats I also have ~20% of users using IE 6 from total IE users, but I will set announcement that they have to migrate to newer version of IE or other browser and problem fixed. I would like to totally eliminate IE6, because when I fix my template I need to spend additional day or even week to fix all bugs in IE 6.

This is stats from one tech site, week stats number of users using IE 4,5 milion. Using IE 8 > 48.40% Using IE 7 > 34,45% Using IE 6 > 16.52% And in global IE takes 32% of all visits. Users that cannot upgrade IE at work can easily switch to other browsers: Mozilla Firefox, Opera, Google Chrome or Safari. I'm with IPB staff it's time to unsupport IE6, support for IE7 and 8 is enough. And just to show you how advanced users of other browsers are: also weeks stats 6.2 milion of Firefox users. 76% Firefox 3.0.11 8% Firefox 3.5 beta 8% Firefox 3.0.10 So if users of other browsers see no problem in upgrading I don't see why would anyone need to support IE6 which needs bunch of code to support it properly. Whats next we will in code see this? // IE 6 .. .. // IE 7 .. .. // IE 8 .. .. // IE 9 .. ..

Just use what is supplied with mysql: "mysqldump"

First rule is that you do not buy hardware for future, but for now. Later on, when load is high you just upgrade to new server. Try to benchmark with APC disabled and see if that helps. With this amount of ram you shouldn't even hit hard those hard drives, so SAS drives wouldn't make any difference. Please while testing paste me top info and do free -m so I can see how much memory you got free. Maybe web server or mysql is miss configured so they are taking all your available physical memory and your server starts to swap. Like I wrote with same box I server in total 75K unique visitors and my average QPS is 180. Under heavy load My QPS goes to 400-500 area without any slowdowns. Also try to disable Memcached and Sphinx and see how your server performs, it is never good idea to install so many things, it is hard to find blame of your high loads which your box should handle without any problem. Nginx is also much faster than Apache so your load should be minimal.

Give us specs how many posts do you have, how many concurrent visitors. And your database how many QPS does it have? You can check that via mysql s. Nginx should handle load much better than apache, I know because I use similar web server and speed is not even comparable. Your sessions should be set to "memory" storage engine instead of "innodb". I don't have such large board, around 100k 1.3k unique visitors but that board takes almost nothing resources. My specs are same as your server, I only have SAS disks instead of SATA MySQL QPS ~180

Finally, if you did it earlier you could avoid all that topics about slow loading. :) This looks like it is fast as 2.3 version or even faster.

That oscillation in loading speed is reason why customers here ask about slow loading. My site is also hosted in US on dedicated server, and when i try this tool which is located in sweden and it is major monitoring service, time deviation which I get is 0.2-0.5 seconds. So fact remains that sometimes forum is loading really quickly and sometimes it is really slow 15+ seconds to load. I think we are paying customers which we pay for access to forums and updates should have site which is loading at decent speeds. And now days even budget quad core could power this site very quickly, so there is no need to invest in Nehalems.

You should say that from start, that is different story then. This random slow downs are definitely not good for business, because most people would relate that to software. You should move to dedicated server with this amount of users and posts, this would eliminate so many questions about loading speed and if this is related to IPB 3 RC.

How many cores 4 or 8? If is 4 that load is so so, if is 8 that is better. If I have to choose i would say it's hardware because slow downs are so random, and if I visit on non busy hours I do not experience any problems.

Still maybe it's time to get better server. This slow downs are not due browser but software or hardware. This topic took 5.2809 sec to generate. You can enable at bottom load value so we can see load of box, I tried to browse the forums 2 topics are fast ~0.5 to generate, and then few are slow.

2GB of ram should be enough, but if is not too expensive you can add 4GB. You could provide as with your url so we can see if is slow for us too.
