./reaim -s100 -e2000 -t -j100 -i100 -f workfile.high_systime

The reaim.config file contains:

FILESIZE 10k
POOLSIZE 1m
DISKDIR /t0
DISKDIR /t1
DISKDIR /t2
DISKDIR /t3
DISKDIR /t4
DISKDIR /t5
DISKDIR /t6
DISKDIR /t7
DISKDIR /t8
DISKDIR /t9
DISKDIR /t10
DISKDIR /t11
DISKDIR /t12
DISKDIR /t13
DISKDIR /t14
DISKDIR /t15

The way Longman uses this is to create 16 ramdisk filesystems through
/dev/ram* and then mount those filesystems to the /t* directories.
Although you could run it through a regular filesystem also. It will use
whatever you place in the reaim.config file as DISKDIR. You can specify
one or more DISKDIR directories.
