Hello: We're running our law school web-site on Zope 2.4.3 (source release, python 2.1, linux2). Zope is running through Apache pcgi. Our Data.fs is about 130MB in size. In addition we have two large directories of external image/external file objects. Occasionally, we see CPU usage shoot to 99.9% when attempting to view large (up to 8MB in size) PDFs stored as ExtFile objects in these folders. The attempted display of the PDF then fails. The folders with the PDFs are on a local 10K RPM SCSI drive. We're using a linux 2.4.x SMP kernel with 2 PIII 500Mhz processors and 1 GB RAM. Load average when not attempting to display the large PDFs is something like: 0.79 - 0.64. Does anyone have any suggestions on how to improve performance for display of these PDF documents?
