Subject: Re: Overhead of highpte (or not :)
Date: 03 Jul 2003 20:53:00 -0700	[thread overview]
Message-ID: <1057290780.18849.37.camel@nighthawk> (raw)
In-Reply-To: <68160000.1057286782@[10.10.2.4]>

After fixing my gcc stupidity
             Elapsed:    User:   System:     CPU:
high pte:    49.962s  578.888s   99.048s  1356.2%
  lowpte:    49.630s  576.242s   90.158s  1342.0%
    ukva:    50.122s  577.164s   88.958s  1328.4%

The increase in elapsed is probably within tolerances.  The system time
isn't :)  The decrease in system time compared to lowpte comes because
the PTE pages are allocated in highmem, and are node-local.  

Differential profiles are up in a bit.
