Quick note on lag spikes

[Genesiser]

Are you someone that suffers from lag spikes? Well for me, the game ran almost lag free for a few weeks and then I started experiencing them quite often. Needless to say, it was very annoying. Anyway, I thought it was something the devs did to screw up the game, but it turns out it was my fault. I realized the lag started after I installed that leatrix latency thing... When I removed it, the lag spikes are gone. So long story short, if you installed that, try removing it to see if it improves the game.

Really, it could be anything that you've installed recently. Always consider what changed since before the issue started.

True, however I have noticed that over the last few weeks, since people initially started talking about the leatrix latency fix that there have been more people talking about lag spikes. So while it's true that anything you could have installed could have caused there to be increased lag, I also see a correlation between the lag spike increases with the leatrix fix. Anyway, I was just throwing this out there for people experiencing lag spikes so if they have the fix installed on their computer, they can try uninstalling it (and restarting computer afterwards) and see if that reduces the amount of lag spikes.

Leatrix Latency fix disables nagles algorithm and adjust the ACK Frequency. Basically it makes your computer send all of its out going packets as soon as possible instead of trying to combine them into more effecient packets. When it's on your packets sit in a buffer within a certain window of time and it optimizes them in that window of time resulting in higher throughput with a fixed pre latency (e.g. it's waiting, so your latency is higher).

Turning it off gets rid of that wait, thus your latency goes down to what it should be. But at the cost of effeciency. You are likely to see a 10% to 50% drop in overall bandwith by turning it off. A 50 meg connection will drop to 30 something on everage and a 25 meg connection will drop to in the 10's to -high teens 10-19 mbps etc (depending on traffic type etc).

The problem is that it affects your upload bandwith too. And on most internet connection Your upload bandwith is a lot lower than your download bandwith.

E.g. My connection is 50 mbps down and 6.5 mbps up.

On connections with low Up streams (e.g. dsl with 1 meg up or lower) or a low upstream in general, Turning off nagles algorithm can do more harm than good by causing your PC to choke on bandwith and then you see REAL Lag spikes, as in it's literally throttiling outgoing server data and you lag like hell.

Based on my observations I would say that in order to use Nagles on a computer, you should meet the following requirements

Available Upload Bandwith With Nagles off | 5mbps
Available Downsload bandwith with nagles off | 10mbps

That's not counting what other programs you have running etc. This game needs at least 2 meg up and 5 meg down to be stable when it get's bursty.
