I'm trying to run the mashup server on RedHat Enterprise linux 4.5 (512Mb RAM, P4-3Ghz Hyperthreading) _or_ on RedHat Enterprise Linux 5 (1024Mb RAM, P4-2.66Ghz).

On both machines I've tried with Sun JRE 1.5 and 6 ( jre-1_5_0_15-linux-i586-rpm.bin  and jre-6u5-linux-i586.rpm ).  In both cases it works but it is TERRIBLY SLOW.  It takes 3 minutes or more to serve up a single html page.  I've also tried on the RedHat 4 machine with LD_ASSUME_KERNEL=2.4.1 setting and with the IBM jre 1.5 ( ibm-java2-i386-jre-5.0-7.0.i386.rpm ) - which fails to create SSL sockets because it's looking for SunX509.   Neither of those options even work on RedHat 5.

If I'm patient enough the product appears to work... but it's so horrendously slow.  Am I doing something wrong?
