I ran tests that I think are similar to what Jason ran on identically
configured FreeBSD and Linux/ReiserFS machines. ResierFS is much much
faster than UFS+softupdates on these tests. 

Linux (2.2.14-5 + ReiserFS):
Time:
        164 seconds total
        97 seconds of transactions (103 per second)

Files:
        65052 created (396 per second)
                Creation alone: 60000 files (1090 per second)
                Mixed with transactions: 5052 files (52 per second)
        4936 read (50 per second)
        5063 appended (52 per second)
        65052 deleted (396 per second)
                Deletion alone: 60104 files (5008 per second)
                Mixed with transactions: 4948 files (51 per second)

Data:
        24.83 megabytes read (155.01 kilobytes per second)
        336.87 megabytes written (2.05 megabytes per second)

FreeBSD 4.3-RELEASE (ufs/softupdates):
Time:
        537 seconds total
        155 seconds of transactions (64 per second)

Files:
        65052 created (121 per second)
                Creation alone: 60000 files (172 per second)
                Mixed with transactions: 5052 files (32 per second)
        4936 read (31 per second)
        5063 appended (32 per second)
        65052 deleted (121 per second)
                Deletion alone: 60104 files (1717 per second)
                Mixed with transactions: 4948 files (31 per second)

Data:
        24.83 megabytes read (47.34 kilobytes per second)
        336.87 megabytes written (642.38 kilobytes per second)

Both tests were done with postmark-1.5, 60000 files in 10000 transactions.
The machines are IBM Netfinity 4000R, the disk is an IBM DPSS-336950N,
connected to an Adaptec 2940UW.
