Hi,
The Specs:
P4 3ghz HT - FSB 800MHz
1GB ECC DDR-SDRAM @ 400MHz
3Ware AMCC 9500S - SATA Raid Card
4 x 250GB Seagate Barracuda 7200.8 SATA NCQ
OS: Windows 2k3 - SP2
ioFTPD version : 5-8-5
ioBanana version: 20
When I test the Raid Speed without any Traffic I get an average Read Speed = 74 MB /s.
See this Pic here :
A speed that satisfies, with crypt, i think.
But now the Problem:
The Speed collapses the more Users are connected and cause Traffic.
On the next Picture you will see what I mean :
At this time there are only 4 Users connected causing a Traffic of ~ 10 Mbit/s and as you can see the average Speed
decreases horrible. Only 40.8 MB/s average Read Speed, and the Graph fluctuate horrible.
And this resumes as more Users are connected.
Here is a Screen what it looks like when ~ 20 Users are connected causing a Traffic of ~ 25 Mbit/s :
Average Speed sinks down to 6.5 MB /s and the System begins to lag,
but the maximum CPU Usage is between 20 and 40 % , that should ´nt be the Problem.
Maybe someone has a suggestion for this problem.
Speed collapses when Traffic (number of Users) is rising
