Ok - the new server arrived today and we have installed it and its online.
Someone talked to me and said that our RAID-5 array could be a part of the problem - its not optimal for the small files that UBB uses. Could this really present a problem?
The new server is a 2.4GHz Pentium Xeon and we made a Raid-1 array (mirror) which is supposed to be the fastest type of RAID. Do I need to tell you that the site is fast now?
BUT: Is this really true - do you need brute force like this? Or have I misconfigurated something...
