Would it be possible for PTCL to turn off interleaving on-demand basis for the customers? firecruz? Others?
I know g.dmt helps a bit too. P.S. PTCL would benefit more by trying to reduce the gateway pings.
Edit: Apparently, maxcom offers the service:[quote=", post:, topic:"]
Those users who primarily use their connection for gaming can have their line modulation changed to fast on Maxcom's service by emailing firstname.lastname@example.org with their userid and request to change modulation to fast. Provided your line is of sufficient quality our team will change your line modulation, though our feedback from most games suggest as long as the pings are consistent the 30 msec difference between Maxcom and PTCL connection makes no significant difference to their gameplay.
Apparently, PTCL uses interleave on by default nowadays. At least gamers would want it to be fast mode instead.
