O2 Wireless Box 2 Running slow for P2P?


[link to this post]
 
I've recently noticed that after O2 have upgraded their routers, using P2P is going much slower...
I looked at the connection statistics in the router and it returned:
Connection statistics:
-------------------------------------------
Maximum number of connections : 2048
Maximum number of halfopen connections : 2048
-------------------------------------------
Number of active connections : 2004
Number of halfopen connections : 512
Number of expected connections : 0
Number of loose connections : 0
Number of closing connections : 0
Number of idle connections : 830
Number of mcast connections : 3
-------------------------------------------
Number of TCP connections : 953
Number of UDP connections : 1050
Number of ICMP connections : 1
Number of non TCP/UDP/ICMP connections : 0
-------------------------------------------
Number of TCP open connections : 38
Number of TCP established connections : 359
Number of TCP closing connections : 556

Stream cache statistics:
-------------------------------------------
Maximum number of hash collisions : 10
% of hash entries with collisions : 89.06
% of hash entries unused : 2.54

CONN/NAT application helper statistics:
-------------------------------------------
Maximum number of helper bindings : 24
Maximum number of connections with helper : 128
-------------------------------------------
Number of helper bindings : 17
Number of connections with active helper : 6


As you can see the number of active connections is very close to the maximum number of connections.

Would this be the problem that is slowing the P2P down, or is it another thing?

Thanks in advance,

In reply to a post by gbhxu:
O2 throttle P2P applications
I beg your pardon?

Would you like to specify on which of the four O2 products they do this, and find out whether the OP is using an affected product as well, before making such a sweeping and if meant to apply to all O2 products then also inaccurate statement?

When you say "upgraded" are you referring to the recent firmware change from V7 to V8? If so, mine is still on V7, and I could compare stats with yours.

You don't say if you are using O2 access or LUU? Mine is LLU.

Where do you get the connection stats? and which P2P software are you using?

Try reducing the number of connections on the P2P client. It's possible that the new firmware takes up more memory in the router so reduces the memory which is available for operation and so is struggling with a full NAT table.

Yeah, P2P has been slow for me since the firmware change to V8.
I'm using LLU.
I get the connection stats from Menu>Connection>Stats when using telnet to connect to the router.

I just tried lowering the number of connections in my P2P client from 400 to 100 and speeds have increased, but are still not getting to their full potential...

Here's my connection stats taken whilst downloading a Linux distro using the BiTtorrent client V6.4, which maxed out at 1.4 MBps (pretty much 100% for my 13.6 meg sync). No sign of any throttling here...

Have you rebooted the router recently, or even reset to factory default?

Re: O2 Wireless Box 2 Running slow for P2P?

I just rebooted my router and about a minute after booting, the active connections go to ~2000 again...

I have around 15-20 computers running on the network including a web server, could this be the cause of the large number of connections on the router?

My sync speed is 6.7mbps.

Is is possible to downgrade to the V7 firmware?

With 20 machines connected it's going to struggle!!

Home networking products are generally designed for around 4 devices to be connected at once. With 20 computers you'd be better looking at business solutions. E.g. a business router / modem router

Accepting what you say, and certainly at twenty users, it does seem to be the case that the v8 O2 box firmwares degrade some aspects of performance. Several reports on the O2 forum on this site.

The v8 introduction seems mainly to have been to improve the security side of things, so extra executing code and additional memory usage, as already mentioned in this thread, could very well be the problem.

Certainly some O2 users have reverted to v7.
