[mapserver-users] High CPU

[Ed McNierney]

Steve -

Would you prefer your CPU was sitting idle?  Keeping the CPU busy is a good thing, isn't it?  It means your network, disk, and other resources are not preventing your CPU from working at full capacity.

What makes you feel that running your CPU at 100% capacity is a bad thing?

The problem is that CPU shoots to 100% while tiles are being generated from
a remote WMS call.

The shp2img dump was taken directly on the server but the problem occurs
when I send remote WMS requests to the server.

I'm starting to think that 640MB RAM isn't enough and I should probably bump
it up to 1GB.

It took 0.3s to run to completion, what's the problem precisely?
