Re: [PERFORM] Maximum Possible Insert Performance?

[William Yu]

This is an intriguing thought which leads me to think about a similar 
solution for even a production server and that's a solid state drive for 
just the WAL. What's the max disk space the WAL would ever take up? 
There's quite a few 512MB/1GB/2GB solid state drives available now in 
the ~$200-$500 range and if you never hit those limits...

When my current job batch is done, I'll save a copy of the dir and give 
the WAL on ramdrive a test. And perhaps even buy a Sandisk at the local 
store and run that through the hooper.
