Hi All,
on our platform, we used a copy with the command "dd" with the block size specification.
the result was not good, because the time of the copy was long for example:
root@T5_ldm_app:/# time sh -c " dd if=/dev/zero of=test.img bs=8k count=100000 && sync"
100000+0 records in
100000+0 records out
real 0m19.121s
user 0m0.172s
sys 0m1.387s
root@T5_ldm_app:/# time sh -c " dd if=/dev/zero of=test.img bs=128k count=10000 && sync"
10000+0 records in
10000+0 records out
real 0m39.056s
user 0m0.020s
sys 0m0.686s
the platform in question is composed of sparc T5-4 and FS1-2.
can someone offer me a solution to reduce this time?
noting that the old platform composed of T4-4 is on which there is more I / O the copy is done in less than 8 seconds.
thanks ALL.
