I have a EC2 server in AWS, 4CPU+16G ram, FreeBSD 10.2R.
Use two command dd and vi:
dd if=/dev/zero of=/.swap bs=1M count=8192 &
8589934592 bytes transferred in 117.074462 secs (73371549 bytes/sec)
when dd run in background, input vi command to edit a small txt file "d.txt"
at same time,
and then write and quit immediately:
/usr/bin/time vi d.txt
49.82 real 0.00 user 0.00 sys
in top command show:
810 root 1 23 0 12344K 2524K wswbuf 0 0:04 5.76% dd
821 root 1 20 0 23448K 4092K wdrain 0 0:00 0.00% vi
vi need almost 50 seconds to quit.
I think some people are already looking at this.. it's not limited to AWS.
any ideas?
