howdy, i'm running the latest apache2, compiled from the ports collection (apache-2.0.52_2; prefork), on a dual 2gHz AMD64 box from ibm. the performance is very bad, with ~ %20 cpu at only ~115 req/s. for whatever reason, almost all of the %20 cpu time is spent in system: CPU states: 0.4% user, 0.0% nice, 17.3% system, 1.3% interrupt, 81.0% idle is there a known problem that could lead to this? i'm a bsd bigot, and after going mad with the IO lockup issues in the kernel that RedHat uses in their AES line (it's truely abysmal), I'd be overjoyed to move everything to BSD, but the redhat boxes on the same hardware aren't even breaking a sweat under the same load. what i'd guess to be the most relevant pieces of hardware that could lead to high system load, the NIC and hard disk controller, are as follows: bge0: <Broadcom BCM5704C Dual Gigabit Ethernet, ASIC rev. 0x2003> mem 0xfe000000-0xfe00ffff,0xfe010000-0xfe01ffff irq 24 at device 1.0 on pci2 mpt0: <LSILogic 1030 Ultra4 Adapter> port 0x3000-0x30ff mem 0xfe040000-0xfe04ffff,0xfe050000-0xfe05ffff irq 26 at device 2.0 on pci2 apache config is: <IfModule prefork.c> ServerLimit 3000 StartServers 100 MinSpareServers 100 MaxSpareServers 500 MaxClients 3000 MaxRequestsPerChild 0 </IfModule> is this a 5.3 issue in general, or specific to the AMD line? any help or tips greatly appreciated.
