You can move database to linux, on all platforms mysql is same.

That tool is standard for benchmarks.

This will work if you have small database, with databases bigger than 200MB you should import your database from shell.

on server where you have apache installed: "ab"

xcache 1.2.x doesn't work under suphp, xcache 1.3.x I haven't tried yet. But like I said in other post you really need to optimize apache and mysql before you make switch to nginx or litespeed. If you have any questions regarding Litespeed just let me know, I use it on few of my sites.

Like somebody said You should hire professional, you have misconfigured Apache and Mysql. Apache spawns too many processes and Mysql is not caching properly. WTF is that your cache limit is higher than your query size? 30 QPS is really low, ATOM 270 can handle that with ease and with 20% load. With similar xeon i had 120 QPS and I never had database error. And you do not need to use mysql persistent links, I do not use it and my avg. connection is 10 max 47. With similar setup (Xeon 3060 and 2GB of ram) I had more than 700 people online with 10 other sites and load avg. was in range of 0.5-1.5. Please post output of this commands: free -m when site is under heavy load vmstat 3 and iostat Thanks

If you want better performance get faster hdd and ensure that you always have enough physical memory.

Do you need screen shots that both of cache is used? I don't know about IPS but there are few applications that are used in that combo with big improvements. Like i said memcached offloads database quite a lot and I have extremely busy database.

On my local machine with no caching page generates in .15s with gzip .14s with xcache .12s with few less queries with xcache, gzip and memcached .07 Memcache saves you queries your db is not so busy, and xcache saves your web server from loading too much because it pulls pages from ram, and it doesn't generates it everytime.

I don't know why nobody recommended it before but why there isn't option to also host signatures on same server as forum. There is no point of having really fast server when I need to wait users sigs to load from bad image hosting services. And every day there are more and more that kind of services, first that comes to my mind is imageshack which most of time is super slow or it timeouts. With that option it would be easier to control size and dimensions of signatures.

Keep us informed, when IPS detect your problem maybe it would help someone in the future.

Hmm that looks OK, I would recommend to report this issue with IPS. After upgrade have you rebuild all the stuff IPS recommends and after that have you optimized your database?

First you need to wait 48h for tuning-primer to examine your settings. Second try to optimize your database, and then check again if there will be slow queries. Third do hdparm -t /dev/hda maybe disk switched to pio mode or something so everything is slowed down, with 11qps you shouldn't have any slow queries. Fourth do also iostat to check if your hdd is too slow, you are really using old hdd.

How many queries per second have you saved with memcache? On my box it is not critical but it's always good to plan ahead, atm I got 163 QPS.

I just had to comment when I saw that you opened 3.0.3 topic, which staff closed very quickly. That is why I said you are acting childish.
