is there any impact on declaring the different segment size on
allocating the same size of binary object on read performance?
and did declaring different subtype would have impact in read
performance ?

i need to know what the blob would actually bring effect on database
write or read performance specially when it come to decide which kind
of sub_type and segment size would be most suitable for me to include
text or the binary object.

i tried to find any impact on database size by using the different
different segment size on allocating the same size of text. but i
failed to view any differences. so i suspect there might be some
impact on read performance .. am i thinking correctly?

any comment would be appreciated.

TIA
