Hello, Do You know what are and what is the source of "D" processes in the htop application? Recently I had notticed that in the peak time from time to I get about 10 to 30 mysql processes marked as "D" - then load goes from 20 to 40 and when D processes are runing only 4 processes are active and CPU usage is about 50-60% then just after the ammount of D processes goes to 0 then I see about 90-120 active processes and CPU usage is 100% on every core of QUAD processor. What could be done to avoid these "D" processes. Have You notticed such problem? I read that it could be caused by huge disk access needs by mysql process, but during this time - mysql disk access is very low - I mean iostat logs very minor ammount of blocks that are written to the hard drive. What is going on?

Hi, what is doing xCache and what is doing memcache if both are enabled in global_conf.php? for sure xcache is caching php code what is doing memcache in that time? Are You using both? What is the impact on the server? Regards YacentY

one more question - how it's possible to monitor if memchache is runing OK, if there are any benefits, which hits are taken by xcache, which ones are taken by memcache and which by mysql? regards YacentY

have You added memcache extension in php.ini config? or it's enabled only in global_conf.php?

so Are You using both? apc and memcache?

could You give some details,, hints how to follow this operation?

I'm already using xcache isn't it same functionality?

Hello, Yesterday I had notticed over 600 QPS on my mysql server so I'm thinking about replication of the mysql server. Have You got experiences with this? Is IPB prepared for such funtionality? How to make mysql performance much bigger? - tweaks were done so next step is relativelly going to new server or maybe replication of DB into 2 servers to make performance bigger. Do You have any hints?

I have four (4) tickets also, two of them are 3 days old, 1 is 1 day, 1 is 2day. When Could I expect solution and my site would work in good shape? Regards

What I could recommned? First of all - dedicated hdd for db - just now I have SAS 2x 146gb 15k rpm in raid stripping mode and performance of DB is brilliant. Second issue is - forget about apache - use something smaller and lighter - example is nginx. After such operations I had reduced costs of the server two times :-) Regards YacentY

I'm wondering my users feeling - that is important

these resaults are very good joke if I would like to put new community on shared server. Probably no way to use IPB if it will be true and not fixed somehow

16 queries - 0.61 seconds - earlier it were about 0.10 seconds. On my 2.3.6 board with 500 users online I don't reach 0.10 for viewing topic or forum so why do we have 0.6 to 2.5 seconds to generate page? I count only data provided from board debug statistics It's easily visible that this site is much, much slower than my server that I figh with it that was very slow - I hope You remember this fights and argues

that's agains our contract as I remember correctly!!! there is a $ in the contract that tells if You have a valid license You are able to get free updates :)

I'm using IPB and also vBulletin on second board so I'm familiar with these 2 boards and with many addons, and I can tell - noone is perfect

lets go to the tracker and see that there is only few unfixed items, so I could imagine release is just comming. There is huge ammount of items done so I hope it's very close to be public

IN_DEV on - what is going on? how to set it up? is there any tutorial?

Hello, I wanted to translate lang pack, and unfortunatelly it broke my english default lang pack - how to restore it now? Thanks and regards YacentY

Hello, I had some issues with MySQL performance, especially when there is over 400users - seems that gallery makes this issue, because when I disable it it runs much faster. I had read few articles about differences between performance of MyISAM and innoBD table types. I'm nearly decided to move to innoDB, but I'm not sure if I have to do this only for some tables or do this for all tables in db, except sessions whil remain HEAP. Do any of You have some experience with performance on both of that db types? My server is DELL PowerEdge 2950III xeon quad core 2ghz, 8gb ram 3x146 gb sas disks in raid5 for system and www, 2x146 gb sas disks in raid0 only for db. Should it faster my site or it's not worth? Thanks in advance BR YacentY

these 2 values changed - but all my tables are MyISAM - how to exchange table to HEAP? thanks in advance BR YacentY
