I have a website using UBBT 6.1.1 , more than 14xxxx posts and 12xxx users , when I tried to upgrade to 6.2 , I found the step 9 takes toooooo much time.... I don't know why it takes so much time. I've waited for one hour in this step , and still waiting NOW.......
I am running tcpdump to observe what the hell is doing between my web and db server (via eth1) , and I found that it seems sending one query per second. Why use such this inefficient way ? It seems updating some column second by second.....
And in my db server , mysql daemon always stick to 99.9% of CPU time ....for at least one hour (not finished yet now...)
Is it normal ? How long should I wait ?
