Vasil,

Thank you for the prompt reply.
And thank you for not chastising me for saying I searched but you found the links for me.

Unfortunately, had already found that page.?? Maybe I am dense as a box of rocks but I couldn't find what I was looking for there.
I was hoping for something like,
The size of the buffer is used while capturing in synchronous mode.?? It is adjustable so that (insert the reason here).?? Make it larger if (insert reason here) but that will cause (insert result here).?? (more explanation......).

Would you know where can find that kind of information?

Thanks again,

Pete

What does:
"output_block_size (default 16*16384)" mean?

I have been searching and I just can't find that explained anywhere.

It's the size of the buffer that's used while capturing in synchronous mode.
