Sziasztok!
A minap beizzitottam elso 64 bites SARGE-mat.
vigyorogtam nagyon, mignem a egy apro pgbench tesztet nem nyomtam..
Osszehasonlitott gepek:
1)
3GHz Intel EM64T proci
1G RAM pillanatnyilag
2xSATA2, soft raid-1 (Intel, ICH7)
2.6.15 vanilla kernel
2)
2GHz Intel P4
512M RAM
ATA133 vinyo
2.4.28 vanilla kernel
Mindket gepen 8.1.2-es pg-t forditottam, tok alapbeallitasokkal, tehat
FSYNC=off volt.
FSYNC = off
-----------
1)
[EMAIL PROTECTED]:~$ pgbench -c 10 -t 1000 -U pgbench pgbench
tps = 110.962078 (including connections establishing)
tps = 110.987545 (excluding connections establishing)
Na, ez LOL!!!!!
2)
[EMAIL PROTECTED]:~$ /usr/local/pgsql812/bin/pgbench -c 10 -t 1000 -U
pgbench pgbench
tps = 310.565960 (including connections establishing)
tps = 310.941348 (excluding connections establishing)
Sima P4 *agyonverte* ....
Miert ?
ha -S -sel futtatom a pgbench-et, azaz read-only tesztek mennek, akkor
mar alakul a helyzet, "FSYNC=off"-nal 5800 tps-t tudott a 64 bites.
Erdekessegkeppen:
1)
[EMAIL PROTECTED]:~# hdparm -tT /dev/md0
/dev/md0:
Timing cached reads: 3676 MB in 2.00 seconds = 1837.89 MB/sec
Timing buffered disk reads: 178 MB in 3.01 seconds = 59.17 MB/sec
2)
[EMAIL PROTECTED]:~# hdparm -tT /dev/hda
/dev/hda:
Timing cached reads: 1724 MB in 2.00 seconds = 862.00 MB/sec
Timing buffered disk reads: 144 MB in 3.03 seconds = 47.52 MB/sec
Nagyon hurkanak tunik "FSYNC=on"-nal ..
Hihetek ennek a pgbench-nek ??
Miert ilyen tetulassu??
Igazibol orulnek ha valaki, akinek nem opteronja van, es van egy kis
ideje, nyomna nekem 1-2 eredmenyt...
Bar az opteron is erdekel, johet az is ...
