Issue
The HP DSS Workflow
server is performing
very slowly when using
OCR.
ENWW
Possible cause
Note that the OCR engine
intensively uses both the
physical memory and the
processor.
The amount of memory
required and the CPU speed
required vary from one
system to the other,
depending not only on the
workload but the average
document size.
Solution
When processing multiple small files
(4 to 10 pages per document), a
smaller configuration might be
required (1 CPU PIII 600 and
512 MB RAM or more running on a
Windows 2000 server with the latest
Service Pack).
If the workload and is large and
the documents are slowing down
the computer, a higher
configuration might be required.
The best way to isolate the cause
of the slowdown is to run one
batch of images and monitor the
following parameters on the Task
Manager:
• The CPU Usage. If the CPU
usage exceeds 90 percent for
the duration of the
processing, a more powerful
processor might be required.
• The Memory Usage. If the
Virtual Memory exceeds
120 percent of the Physical
Memory during the
processing time, more
Physical Memory might need
to be installed.
• The Virtual Memory. If a
large Virtual Memory file
exists, it will slow the
computer, even though the
computer will complete the
job.
