Hi. Is using datasource clob=yes affects to perfomance or not? I have some long content fileds in my database, but it cuts by 64000 bytes. For these fields I use clob=yes DSN, but mayabe that's ok change main DSN to this option

nah, i think it's more of a left over from the 90s TBH

Everywhere I've worked within the past long time always has it enabled if there are for instance textareas. Never saw a downside, and TBH, if there is one, chances are high every app has much worse db bottlenecks.
