Chrome vs Firefox 12.0, my memory usage tests
Test involves two windows, one with 10 tabs and another with 3 tabs, running on OSX 10.7.3
Before running either:
Wired Memory: 1309 MB
Active Memory: 3260 MB
Inactive Memory: 614 MB
Free Memory: 2546 MB
Real Mem Total (ps): 2460.141 MB
After starting Chrome:
Wired Memory: 1331 MB (+22 MB)
Active Memory: 3990 MB (+730 MB)
Inactive Memory: 640 MB (+26 MB)
Free Memory: 1773 MB (-773 MB)
Real Mem Total (ps): 3555.176 MB (+1095.035 MB)
After viewing each tab (versus before start):
Wired Memory: 1323 MB (+14)
Active Memory: 3981 MB (+721)
Inactive Memory: 650 MB (+36)
Free Memory: 1781 MB (+781)
Real Mem Total (ps): 3563.785 MB (+1103.644)
Now let's close Chrome (versus before starting Chrome):
Wired Memory: 1309 MB
Active Memory: 3265 MB (+5)
Inactive Memory: 622 MB (+8)
Free Memory: 2530 MB (-16)
Real Mem Total (ps): 2460.895 MB (+0.754)
Time for Firefox:
Wired Memory: 1333 MB (+24)
Active Memory: 3625 MB (+360)
Inactive Memory: 740 MB (+118)
Free Memory: 2033 MB (-497)
Real Mem Total (ps): 2958.316 MB (+497.421)
And after viewing each tab (versus before start):
Wired Memory: 1324 MB (+15)
Active Memory: 3639 MB (+374)
Inactive Memory: 748 MB (+126)
Free Memory: 2018 MB (-512)
Real Mem Total (ps): 2968.293 MB (+507.398)
Now with Firefox closed (versus before starting Firefox):
Wired Memory: 1310 MB (+1)
Active Memory: 3279 MB (+14)
Inactive Memory: 636 MB (+14)
Free Memory: 2505 MB (-25)
Real Mem Total (ps): 2478.117 MB (+17.222)
So that is Chrome using more memory versus Firefox, and here's how much:
Wired Memory: -1 MB
Active Memory: +347 MB (92.7% increase over FF)
Inactive Memory: -98 MB (77% decrease over FF)
Free Memory: +269 MB (52.5% increase over FF)
Real Mem Total (ps): +596.246 MB (117% increase over FF)
Pass #2 for Chrome, before running:
Wired Memory: 1345 MB
Active Memory: 3155 MB
Inactive Memory: 606 MB
Free Memory: 2676 MB
Real Mem Total (ps): 2393.332 MB
After running:
Wired Memory: 1347 MB (+2)
Active Memory: 3819 MB (+664)
Inactive Memory: 621 MB (+15)
Free Memory: 2016 MB (-660)
Real Mem Total (ps): 3414.230 MB (+1020.898)
Again we see Chrome using more memory than Firefox.
Sans Digital 4-port eSATA PCIe Host bus adapter (HA-DAT-4ESPCIE) Review
Today I'm reviewing the Sans Digital 4ESPCIE four eSATA Ports PCI-Express (x8) Host Adapter
. The Sans Digital 4ESPCIE
HA-DAT-4ESPCIE uses a Silicon Image 3124 (Sil3124) chipset, and has 4 pairs of LED pins, one for each eSATA port. It has one jumper set for Enabling (Pin 1+2) and Disabling (Pin 2+3) the Bios. On the back is a sticker labeled "ESATAPCI8 , 1211081"
This controller will be connected to a Sans Digital TowerRAID TR8M+B - 8 Bay eSATA JBOD Performance Tower with 6G PCIe Card (Black)
, a very capable JBOD enclosure I have been running for 2 months now.
With the BIOS enabled, at BIOS start only one drive shows, drive 1, in my Sans Digital SATA enclosure. However, when boot into Ubuntu Linux, all drives activate fine through AHCI kernel driver.
When booted into Gentoo however, only one drive showed up.
# lspci:

After running for 6 days, system is completely stable and performance is much better compared to my prior eSATA setup.
This is certainly a great inexpensive alternative to a more expensive SAS deployment.
More test results to come...
