Hi, This code at xserver/os/io.c ~line 459 .... if (SmartScheduleDisable) if (++timesThisConnection >= MAX_TIMES_PER) YieldControl(); .... is either obfuscated or wrong? .... if (SmartScheduleDisable && ++timesThisConnection >= MAX_TIMES_PER) YieldControl(); .... is what it does at present. Thanks, Colin Harrison
