I upgraded our PIX 515 from 5.3(4) to 6.2(2). I did it to try to take advantage of the PDM. I noticed that after the upgrade, it seemed more sluggish in my preliminary testing [Going out and coming in, loading web pages, etc.]. It's a PIX-515, 64 MB RAM, CPU Pentium 200 MHz, Flash 16MB. Also Active FTP would not work from outside to inside the FW. Active FTP worked with the older version, but not the newer one. Has anyone experienced this behavior before? Is there a fix?
