P2Pool Latency slowly rising

[jvamos]

Hey all,

I have noticed that the latency has been rising in general. I still fall back to 0.4s and below but the general trend seems to be an upwards curve. I was wondering what kind of things could influence that kind of behaviour. Network traffic is fairly stable and definitely not following the same trend.  What kind of things affect latency. Topology seems to have no effect.

latency ?

I'm assuming you're referring to the GBT latency.  That's wholly dependent upon your CPU/RAM.  Some people have successfully created a huge virtual RAM drive and keep the entire blockchain there, and they've got absurdly low GBT latency because of it.

I will give that a whirl, I had an SSD on standby that I can use.

An SSD will certainly provide faster I/O time than the mech drives.  I was referring to creating a RAM drive and using that as the data directory for bitcoind.

Assuming some flavor of Linux:

Code:

mkdir /mnt/ramdisk
mount -t tmpfs -o size=50G tmpfs /mnt/ramdisk

This of course assumes you've got enough RAM to cover that request.  Then you put the bitcoin data directory there, start your bitcoin daemon to point to the new ramdisk data directory.

no needed with v0.9.x ... Bitcoin Core have a CACHE (from 4mb to ...) and work very well to not use hard drive.

p2pool has its own support thread please use. No need for another thread.
