Subject: makedumpfile 1.5.0 takes much more time to dump
Date: Thu, 20 Sep 2012 16:06:34 -0400 [thread overview]
Message-ID: <20120920200633.GL4681@redhat.com> (raw)
Hi Atsushi san,
We tried makedumpfile 1.5.0 on a 1TB machine and it seems to regress
badly. We reserved 192MB of memory and following are test results.
#1. makedumpfile-1.4.2 -E --message-level 1 -d 31
real 3m47.520s
user 0m56.543s
sys 2m41.631s
#2. makedumpfile-1.5.0 -E --message-level 1 -d 31
real 52m25.262s
user 32m51.310s
sys 18m53.265s
#3. makedumpfile-1.4.2 -c --message-level 1 -d 31
real 8m49.107s
user 4m34.180s
sys 4m8.691s
#4. makedumpfile-1.5.0 -c --message-level 1 -d 31
real 46m48.985s
user 29m35.203s
sys 16m43.149s
Thanks
Vivek
