actually on two separate sites.
both had been relatively stable for years, and then randomly, began to slow, slow, slow, until they were 90% unresponsive...
I spent weeks trying to figure out what was going on.. still am not 100% certain, all that I do know is that the instant I disabled the random image block- they were back fully functional again.
I upgraded to 1.5.6 on both- same issue still remains.
has anyone heard of similar? are their any ways to correct this?
