|
|
|
|
<P>With the standard version of the 2.0.x kernels you get the 0.26 version
|
|
of the ppa.c program. This is a very reliable simple program. It
|
|
has gotten a lot of use and abuse and held up rather well. The only bad
|
|
thing about this program is that it's not very fast. On my machine I have
|
|
version 2.0.30 kernel, and 2 parallel ports. This is also a low-buck
|
|
machine pentium 133 - 16 meg memory, 5 gig maxtor eide hard drive. The machine
|
|
cost me 500. U.S. Dollars and the drive was 250. I am cheap but so what.
|
|
<P>I had the ZIP drive on
|
|
the second port and the printer on the first port. The second port
|
|
was an old add in card, no epp mode. This made the driver run in 4 bit mode.
|
|
<P>To base line the performance I copied the netscape tar file from the hard
|
|
drive to the zip drive. This file is about 10.6 meg.
|
|
Time 7 minutes 15 seconds. Going from the zip
|
|
drive to the hard drive was about 7 minutes even. Not exactly setting the
|
|
world on fire.
|
|
<P>I then made 2 changes. First I switched the ZIP drive to the first
|
|
port and went into the bios and set EPP mode on for the first port.
|
|
At the same time I hooked up the printer to the 2nd port.
|
|
<P>Second change I went out and downloaded the new version of the program
|
|
from
|
|
<A HREF="http://www.torque.net/~campbell/">David Campbells page</A>
|
|
Then I installed this program. Check out
|
|
the readme file that is included.
|
|
<P>Then I ran the same test again of copying the Netscape tar file to and
|
|
from the ZiP drive. The copy to the C drive was 1:55 seconds. From the
|
|
hard drive to the Zip drive was 1 minute flat. This compares to 7:15 and 7:00
|
|
with the old program. This was a big improvement over the 0.26 program.
|
|
This was also using the zip drive as a vfat file type.
|
|
<P>Next I formated a zip drive in ext2 format. Ran the same test again.
|
|
The copy going to the hard drive was only 50 seconds. The copy from the
|
|
hard drive to the Zip drive was only 40 seconds.
|
|
<P><B> Performance Summary </B>
|
|
<P>For this test case of moving a 10.6 meg file,
|
|
the 4 bit standard port mode and program version 0.26 is the slowest
|
|
7:00 and 7:15
|
|
<P>The new program (1.41) and EPP mode with ext2 file types is the fastest
|
|
at 50 seconds and 40 seconds.
