Solaris 10
Apache version: 2.2.11 & 2.2.17 (32 &64 bit)
We recently moved our production webserver from a sparc platform (T2000) to an
x86/64 platform (x2270-m2) and we have noticed an erratic response time for
downloads of files using SSL. This seems to randomly occur with any files about
10k or larger. For instance, I have been using a test file of 140K, and it can
take 0.5 or 4.8 seconds to transfer. When using the sparc platform, it always
only takes 0.5 seconds.
I noticed this as we are using an external monitoring system (Gomez.com) and we
started seeing these wildly varying times for transaction processing.
I have tried a cut down SSL setup for testing, and examined every directive and
option, and I can't make sense of the problem. I'm using the following
configuration string, and I'd be happy to include the configuration setups..
./configure --prefix=/app/www/apache-2.2.11_32 --with-mpm=worker --enable-ssl
--with-apr=/app/apr-1.3.3-32 --with-apr-util=/app/apr-1.3.3-32
--enable-mods-shared="headers expires deflate"
Server version: Apache/2.2.17 (Unix)
Server built: Jan 5 2011 15:56:01
Server's Module Magic Number: 20051115:25
Server loaded: APR 1.3.3, APR-Util 1.3.4
Compiled using: APR 1.3.3, APR-Util 1.3.4
Architecture: 32-bit

Server compiled with....
-D APACHE_MPM_DIR="server/mpm/worker"
-D APR_HAS_SENDFILE
-D APR_HAS_MMAP
-D APR_HAVE_IPV6 (IPv4-mapped addresses enabled)
-D APR_USE_FCNTL_SERIALIZE

-D DEFAULT_ERRORLOG="logs/error_log"
-D AP_TYPES_CONFIG_FILE="conf/mime.types"
-D SERVER_CONFIG_FILE="conf/httpd.conf"
I can move the bare-bones configuration between the sparc and x86 platforms and
get normal response on the sparc, and irregular on the x86.
Any help would be appreciated.
