About Cache Memory On R2

[ICTCity]

even I don't know which interface is the storage one, I take the biggest value (16'126'929) and after some calculation you have 16 MB/s in 5 mins which is... NOTHING!

So there's something wrong somewhere. I mean... ok you haven't much traffic but ehi.. 16 MB/s looks pretty bad ^^

Can you please repeat the same thing BUT this time include storage and do what I told you before (copy a file).

Post results

All interfaces (supposedly) have an direct connection to an Iscsi disk.

192.168 (STORAGE LAN)
10.95 (SERVER and uses lan)

EXCEPT First Connection (the one with 16GB). This connection has another IP (other lan)

All interfaces except Citrix PV Ethernet Adapter has an 192.168 IP
But Citrix PV Ethernet Adapter has an 10.95 IP, 10.95 is the users lan

When we make a SQL query the traffics goes for Citrix PV Ethernet Adapter_4 (192.168)
When we make a DBF query or process the traffics goes for Citrix PV Ethernet Adapter (10.95)

So the dbf traffics goes for users lan.

If you want to see a pic of this please ask and i will upload

I see that this could be the problem, because we have problems with dbf process (too long). IF traffic goes for users lan, and not for storage.

Another test:
5 am run a process took 4 secs
9 am the same process took 30 secs
Only diference is the users connected.

Thans again!!!

That's because I need that you monitor and post results, if not I can't see how much traffic is generated.

Anyway... I never heard that you have multiple connection with different IPs and interfaces on the same storage to different disks... I mean... not in this way. Anyway it doesn't matter.

Be sure to understand that YOU DO NOT HAVE 16 GB, take a look at the last row: it says BYTES \ s which mean BYTES which are NOT 16 GB

1 GigaBYTES = 1'000'000'000 BYTES

Again, monitor and make the copy and paste test

my mistake.

And my mistake forgot say this change we do last weekend, every disk has a direct connection to storage.


I'll try to find NETWORK STORAGE AND LAN in perform (only find Network Interface) and post results.
thanks

You will not find net and storage I mean that I want to see your network like now AND you disk performances.

 

[abitguru]

hope this helps, I not really into performance monitor
Disk.

copy a large file (~ 2GB)

 

[ICTCity]

Ok we are almost there... Now do the same test (copy file) and this time monitor the network and post result. I need to understand who is chocking everything
