dear Eric,

many thanks for your quick response.

PCQ Linux 9 is called as PC Quest Linux 9 (distributed by PC Quest
magazine), which is roughly similar to RedHat Linux 9.

i was running IMAGR with DOTV=1 and similarly while running TVFLG.
it was slow only mainly while displaying/manipulating the image on TV.

all through after Linux installation, i have been running by just saying 
"aips" (i.e. without TV=LOCAL) option.
yes, i just now did run with TV=LOCAL option, it did become a lot faster.
it is surprising "unix sockets" option is faster than "internet sockets".

i now re-ran by saying "AIPS" (without TV=LOCAL) and i did not find
IMAGR/TVFLG to be terribly slow as i had experienced earlier.

well, the messages that i got are as follows:

1) if i say just "aips" and run it gives the following
