Currently I am running several J2EE applications with the Orion application server on a dedicated host box at an ASP. Here are the specs of the machine: 4.11-STABLE FreeBSD 4.11-STABLE Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-p7-jstepka_23_may_2005_06_13) CPU: Intel(R) Celeron(R) CPU 2.40GHz (2412.08-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0xf41 Stepping = 1 Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,A CPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> real memory = 1065287680 (1040320K bytes) avail memory = 1031368704 (1007196K bytes) Preloaded elf kernel "kernel" at 0xc0560000. Warning: Pentium 4 CPU: PSE disabled Pentium Pro MTRR support enabled I am starting my Java instance with: /usr/local/jdk/bin/java -server -Xms128m -Xmx384m -Djava.security.egd=file:/dev/urandom -jar orion.jar The problem I have is that my Windows 2003 server environment where I am doing much testing of several of the applications is running MUCH faster than the dedicated FBSD host. Is there some type of tuning option that I could enable to get the system to run faster? If additional information is needed, I would be more than happy to supply this data.
