Random lag, all zones, only on one character on one account

[Bokke]

Hello,

I am experiencing random lag spikes that last <0.5 seconds and occur several times a minute, but only on one character on one of my accounts.

I play my other accounts more frequently and this has never occurred. It does not seem to be happening on other characters on the same account.

It's been on going for a month or two now, I believe there may have been a patch around when it started but I don't recall.

It does no happen when a friend plays the same character.

Any assistance will be greatly appreciated.

edit: I did not notice them while leveling up in permafrost but noticed them when I first arrived in Kunark. Since them ive noticed it in every zone.
