XenForo + caching = AMAZING

[MattW]

You are missing a comma? -o slab_reassign,slab_automove NOT -o slab_reassign slab_automove
Never mind, top is yanking the comma for myself also:


How is the graph, is the waste lower?

Even when I start memcached manually, it doesn't display commas in the ps -ef output

[root@vps2 ~]#/usr/local/bin/memcached -u root -m 32 -p 11211 -u nobody -l 0.0.0.0 -o slab_reassign,slab_automove

output

# ps -ef | grep memcache
nobody    4846  4678  0 09:02 pts/0    00:00:00 /usr/local/bin/memcached -u root -m 32 -p 11211 -u nobody -l 0.0.0.0 -o slab_reassign slab_automove

 

[MattW]

Ah, just seen the edit you made

 

[Floren]

I too have a lot of wasted space and also a large amount of free memory.

OK, I feel better, I thought I missed something into setup. Thanks Deebs.
P.S. Did you finished the camo setup? Go visit our thread and post an update there... I finished the RPM's, I'm dealing with the crazy format camo is written and the fact they go in circles loading useless daemons.

 

[MattW]

My waste is still at 64.5%

How busy is your site?
2 days on 1.1.14 with the new libs and I have like 25% of memory used:

 

[MattW]

lol, it's strange though, as my other server isn't that high, with exactly the same set up

Main VPS

Used 21.0 MBytes
Total 32.0 MBytes
Wasted 20.6 MBytes

Second VPS

Used 8.0 MBytes
Total 32.0 MBytes
Wasted 7.9 MBytes

 

[Floren]

Updated the post with a graph taken just now. 64MB of ram assigned...
Are you caching the Xenforo sessions?

Not very busy at the minute, will be interesting to see what it's like after the weekend, as that is when we are busiest.

Just wondered if any of you know why I get so many failures when I run memcapable? 44 of 54 tests failed.

All of the binary tests fail with connection error - is this because I don't have igbinary installed?

TBH it seems to be running okay, so not sure if it's because I've got an older version installed with no binary support?

I've changed the config for each of my XF installs to use 'Libmemcached' for the backend and they seem to be working okay, and phpMemcachedAdmin reports connections etc. so presumably it's all working as expected:

 

[MattW]

How did you install memcached?

Since installing igbinary, I've set php and apc to use it as well.

 

[CTXMedia]

I didn't, my host installed it years ago. Maybe I ought to look at updating it?

 

[MattW]

I re-installed the PECL memcache on mine after reading this thread, so I could configure it with libmemcached and the json/igbinary support.

I'm currently running Memcached Server Version 1.4.13

with PECL memcached-2.1.0

How did you set it up to work with libmemcached?

I installed libmemcached, json and igbinary, and then installed PECL memcached

pecl download memcached
tar -xzvf memcached-2.1.0.tgz
cd memcached-2.1.0
phpize
./configure --enable-memcached-igbinary --enable-memcached-json
make
make install

 

[CTXMedia]

Sorry, I'm getting myself confused. My host installed Memcached Server years ago and that hasn't been udpated - it's on version 1.2.2

I'll have a look at updating it to a later version over the weekend and then review Libmemcached again.

Thanks,
Shaun

 

[CTXMedia]

Oh, okay then, I'll do it now ....

Updated Memcached server to 1.4.13:

 

[Floren]

I'm glad I got you all excited about Libmemcached.
I'm running Memcached 1.1.14 btw.

I've also now installed igbinary to use as the PHP serialiser and resolved the previous memcache.so / memcached.so issue; I edited /etc/php5/conf.d/memcache.ini and commented out the second line to stop it loading the memcache module. Then created /etc/php5/conf.d/memcached.ini (using your example earlier in the thread Floren - thanks ) and stopped and restarted Apache2. This time it came up okay with no errors and phpinfo.php reports only the memcached module loaded (no sign of memcache!).

So, gentlemen, I think I'm done. Up to date and running smooth. Many thanks for the hints and inspiration to update/change it.

Cheers,
Shaun

 

[Floren]

Welcome to 2008. Congrats on updating your server.
Next, I dare you to switch to a fully mysqlnd supported PHP environment and OpenSSL 1.0.1c.

 

[CTXMedia]

lol ... erm, maybe later Floren.

I do have an issue though since moving over to libmemcached - my XenSSO slave add-ons are now all broken so I've had to temporarily disable them:

Not sure if this is an add-on coding issue or whether it's an OS issue - something I've missed, forgotted, not set?

Ever come across this?
