disk performance with small files

[MoshiachNow]

HI,
Using AIX 4.3.3 with ML10.

I have some disk that gives a nice 20MB/sec read for 100MB files.

However,when reading lots of 100KB file s- the performance frops 10 times.
I would appreciate any suggestions.

My current vmtune setting are:
vmtune: current values:
-p -P -r -R -f -F -N -W
minperm maxperm minpgahead maxpgahead minfree maxfree pd_npages maxrandwrt
13104 39314 16 4096 120 4300 524288 0

-M -w -k -c -b -B -u -l -d
maxpin npswarn npskill numclust numfsbufs hd_pbuf_cnt lvm_bufcnt lrubucket defps
104838 6656 1664 1 93 96 9 131072 1

-s -n -S -L -g -h
sync_release_ilock nokilluid v_pinshm lgpg_regions lgpg_size strict_maxperm
0 0 0 0 0 0

number of valid memory pages = 131047 maxperm=30.0% of real memory
maximum pinable=80.0% of real memory minperm=10.0% of real memory
number of file memory pages = 110713 numperm=84.5% of real memory "Long live king Moshiach !"
