Hi.

I have just gotten 2.0 on a HP Vectra 486/SX-25. An identical machine
runs 1.x unpatched-final-current.

The 2.0 machine just came up day before, and I've been configuring things.
Somehow, the machine feels slower. Iozone indicates the 2.0 machine gets
faster as the file size gets bigger, but things like formatting man pages
take very long.

Both machines have identical hardware, and both kernels are configured
for the barest minimum. Only difference is the 2.0 kernel has mcasting
and mrouting. 

1.x$ iozone 20
   Writing the 20 Megabyte file, 'iozone.tmp'...48.633333 seconds
   Reading the file...86.566667 seconds
   
   IOZONE performance measurements:
           431216 bytes/second for writing the file
           242258 bytes/second for reading the file
   
2.0$ iozone 20
   Writing the 20 Megabyte file, 'iozone.tmp'...59.734375 seconds
   Reading the file...43.296875 seconds
   
   IOZONE performance measurements:
           351079 bytes/second for writing the file
           484365 bytes/second for reading the file

1.x$ time man netintro
       14.78 real         7.58 user         4.01 sys

2.0$ time man netintro
       52.76 real        31.24 user        15.62 sys


What should I be looking at? TIA. Cheers.
