PSF/AIX performance with large AFP files
ITEM: RTA000155728

Topic thread:
Printer Systems (PRINT - NA/ATS)
PSF/AIX
Hi, we have a customer that sends ascii files to another company; the
second company uses PSF/6000 and two IP3900 to construct and print those
applications. Now the first customer is changing his system to generate
AFP files, so they are going to give AFP files instead of ascii
files to the second company. The second company argues that they will
have performance problems with the large AFP files generated in the
first company. Is this right??? Are there problems trying to print large
AFP files already generated using PSF/6000, do we have to segment those
file to a specific size????
Thks in advance.
A:
In general, there should be less of a load on the PSF/AIX system since
they don't have to convert from ASCII to AFPDS. The conversion from
AFPDS to IPDS (to the printer) is fairly simple since the two
architectures are so similar. Disk space is another question.
The first question is, "how large are the AFPDS files?".
Is the first company planning to send AFP resources inline in the
data stream, or are they just going to send the AFPDS file with
references (pointers) to the external resources (fonts, overlays,
page segments)? Certainly, the latter would be smaller than the
former. I would not recommend including fonts inline as those would
definitely increase the size of the AFP file. Also, note that the
size of the AFPDS file will depend on how efficiently the AFPDS
generator creates the AFPDS.
I think we would need more detail on the exact content of the AFPDS,
the method the first company is using to send the file to the second
company (FTP, tape, etc.), what level of AIX the second company is on,
how much disk space they have, and of course, the size of the AFPDS
file. There's no way to tell without additional information or actually
looking at the file the first company generates; the AFPDS could be
reasonably small and efficient, or it could be quite large if it
includes inline resources and/or is inefficient AFPDS.
If you can get additional information on the questions asked, I'll be
glad to try to help further.
