| |
Hi all,
today I tested the harddisk-performance of my server (EIDE/2.0.36),
dd if=100M-File of=/dev/null needed 16.5sec ==> 6M/sec (good for an old AMD K5 based on an old mainboard). This server is direct connected to my other mashine via 5m C5 X-link cable (this should be ok). Both mashines have a "D-Link somewhat"-card based on DEC 21140 ("tulip"/100MBit).
Reading the same file over nfs on my other mashine´s /dev/null needs >50 seconds, this is less than 2 M/sec.
What is the problem? Where is the real "bottleneck" (is this right word in english too?) on the data´s way?
technical details of the mashines:
server (rhb): "other" (rhb1): CPU: AMD K5@133 MHz AMD K6-2 300 @300 MHz RAM: 64M EDO 96M SDRAM NIC: ------- D-Link based on DEC 21140/ 100MBit -------- HDD: IBM DTTA#??? (10 GB, 5400 RPM) isn´t interesting
SYS: 2.0.36 (no patches) 2.2.1 (no network-relevant patches)
Have a look on the bing-results in the attachment.
What else do you need? What else may be useful to find the real bottleneck?
