what does "how slow things are"
and presumably the other coldfusion box is running fine at the same time
that the debian box was slow ??
- what is the swap space being used from free or top
- if you have more than 64MB of swap being used, you probably want
to add more physical memory. add as much memory as swap being
used ( using swap space is too slow )
- is DMA turned on ?? ( on presumably your ide disk ) and not an
scsi-based system
- what speed cpu are you running and fsb config
- how fast can you compile the linux kernel on that same box ..
( should be about 5 minutes to compile linux-2.4.26 or linux-2.6.7
( on a typical 1G cpu w/ 512MB of memory
- celeron will compile in about 8-10 minutes
- how fast can you trasfer 20MB files from xx machine to/from yy machine
across the network
- what was the debian machine doing during the "time the coldfusion box
was slow"
- what jobs is it running ..
- was there any hung networks (df should finish almost instantly)
- on and on ...
