SPECweb99_SSL Result =============================================================================== || IBM : xSeries 440 || CD SPECweb99_SSL Red Hat : Zeus V4.1R1 || || =============================================================================== SPEC has discovered a code defect in the SPECweb99_SSL test harness run on the client systems used in this result. The bug prevents these client systems from generating the correct SPECweb99_SSL workload. Specifically, the bug in the SPECweb99_SSL code results in the clients not generating any of the required SSL ClientKeyExchanges during the benchmark. Therefore, the results presented here are not comparable with any other SPECweb99_SSL results. =============================================================================== PERFORMANCE | Conforming Simultaneous Iteration | Connections ---------------+---------------------------- 1 | CD 2 | CD 3 | CD ---------------+---------------------------- Median | CD =============================================================================== Availability Dates All Hardware Mar-2002 HTTPS Software Mar-2002 Operating System May-2002 Supplemental System May-2002 Hardware Vendor IBM Model xSeries 440 Processor 1.6 GHz Intel Xeon MP # Processors 4 cores, 4 chips, 1 core/chip Primary Cache 12KBI + 8KBD on chip Secondary Cache 256MB L2 Other Cache 1MB L3 cache and 32MB L4 cache Memory 4 GB Disk Subsystem 7 x 18GB ST318451LC Disk Controllers On-Board Adaptec SCSI Other Hardware 2 x Alteon ACEswitch 180 Software Operating System Red Hat 7.2 Linux with a 2.4.18 Kernel File System Ext. 2 Other Software IBM Summit chipset patchs Intel 3.6.8 driver HTTPS Software Vendor Red Hat HTTPS Software Zeus V4.1R1 API Zeus PEPP 0.6 ISAPI used for dynamic content Server Cache None Log Mode Zeus Binary CLF Test Sponsor Test Date Jun-2002 Tested By IBM SPEC License 11 Network # of Controllers 2 Network Controllers Intel Pro 1000 # of Nets 2 Type of Nets Gigabit Ethernet Network Speed 1 Gb/s MSL (sec) 30 (Non RFC1122) Time-Wait (sec) 60 (Non RFC1122) MTU 1500 Clients # of Clients 10 Model IBM xSeries 330 Processor 1.13Ghz Pentium III # of Processors 1 Memory 256MB Network Controller Alteon ACENIC Operating System Windows 2000 Compiler Visual C++ 6.0 Benchmark Configuration Requested Connections 1170 Fileset Size (MB) 3864.96 =============================================================================== Notes/Tuning information SUT Notes 1 disk for OS 5 disk software RAID0, using 64KB chunk size, for web pages 1 disk for logs Operating System Notes Tuning parameters: - net.ipv4.ip_forward=1, default 0 - net.ipv4.conf.all.rp_filter = 1, enables source route verification, default 0 - net.ipv4.tcp_timestamps = 0, turns TCP timestamp support off, default 1 - net.ipv4.tcp_max_tw_buckets = 2000000, sets TCP time-wait buckets pool size, default 180000 - net.core.rmem_max = 10000000, maximum receive socket buffer size, default 65535 - net.core.rmem_default = 10000000, default receive socket buffer size, default 65535 - net.core.wmem_max = 10000000, maximum send socket buffer size, default 65535 - net.core.wmem_default = 10000000, default send socket buffer size, default 65535 - net.core.optmem_max = 10000000, default 10240 - net.core.hot_list_length = 10000, maximum number of skb-heads to be cached, default 128 - net.ipv4.tcp_rmem = 30000000 30000000 30000000, maximum TCP read-buffer space allocatable, default 4096 87380 174760 - net.ipv4.tcp_wmem = 30000000 30000000 30000000, maximum TCP write-buffer space allocatable, default 4096 16384 131072 - net.ipv4.tcp_mem=30000000 30000000 30000000, maximum TCP buffer space, default 31744 32256 32768 - fs.file-max = 81920, maximum number of open files, default 1024 See x440config for kernel build information HTTPS Software Notes Zeus Configuration - tuning!bind_any yes - tuning!cache_files 8192 - tuning!cache_flush_interval 31536000 - tuning!cache_large_file 1048576 - tuning!cache_max_bytes 0 - tuning!cache_small_file 4096 - tuning!cache_stat_expire 31536000 - tuning!num_children 16 - tuning!so_wbuff_size 1048576 - tuning!softservers no - tuning!unique_bind no - tuning!use_poll yes - tuning!cache_cooling_time 0 - tuning!cbuff_size 65536 - tuning!ssl_sessioncache_size 5011 - tuning!ssl_sessioncache_expiry 120 - tuning!ssl_keepalive yes - tuning!ssl_diskcache yes - tuning!keepalive yes - tuning!sendfile yes - tuning!sendfile_minsize 1 - tuning!sendfile_maxsize 2147483647 - tuning!listen_queue_size 8192 - tuning!so_rbuff_size 0 - tuning!modules!cgi!cleansize 0 See Zeus-tuning.txt for a description of the Zeus tuning parameters ISAPI Source code is available in the SPECweb99 support docs as IBM-20011019_1-API.tar.gz =============================================================================== Test Run Details Run Conforming Percent | Throughput Response ops/sec/ Kbits/ Num Connections Conform | ops/sec msec loadgen sec => 1 CD CD | CD CD CD CD 2 CD CD | CD CD CD CD 3 CD CD | CD CD CD CD
