General Notes / Tuning Information




*Following are the OS Tunings only for all the Servers and Clients, not any installation steps

**set rlim_fd_max=1048576: Hard limit on the open file descripters for a single process

**set autoup=36000000: Controls the frequency in seconds of entire physical memory to be scanned for dirty pages

**set tune_t_fsflushr=600: Reduces fsflush daemon overhead

**set rlim_fd_cur=1048576: Defines a "soft" limit on file descriptors that a single process can have open

*Following are the NETWORK Configurations and Tunings

**All the network connections and the routing are resolved using UNIX hosts file

**All total 15 Java load generator instances were configured on the 1 Sun Fire X4600, 1 Sun Fire X4275 and

***1 Sun Fire X4240 Clients at the 1200-1214 ports for all IMAP users

***1 Java load generator instance was configured on the 1100 port for the

***SMTP sink. Following Java options were used for the load generators:

***java -d64 -Xms4096m -Xmx4096m -XX:+AggressiveHeap

**The Benchmark runs through a private network between the load generators

***and the SUT via a Gigabit Ethernet Switch

***The Mailserver is attached to 2 Sun Storage 7310 Unified Storage Systems NAS Appliances

***Each 7310 is equipped with 2 AMD Opteron, Model 2356, 2.3GHz, 32GB memory,

***attached with 1 J4400 (24x1TB 7200RPM SATA disks) JBOD array

***and configured as 2 mirrored devices and 4 shared ZFS volumes on each mirrored device

***The SUT is connected to 7310s via Dual 10 Gigabit Ethernet Fiber

***Total 8 volumes are mounted on the SUT Mail indexes and Mail messages using NFSV4 protocol. Following mount options were used

***nointr,hard,xattr

***Availability of the mailstores maximizes with the UPS protected Storage Systems

***2x146GB, 10Krpm internal SAS disks are used on the SUT for System OS and swap, 4 internal SSDs(32GB each) were configured as 4 seperate ZPOOLs and 4 ZFS file systems used for log, queue, store metadata and LDAP

Errors




    

    There were no errors reported in the raw file.



    

    There were no Quality of Service (QoS) failures.





Warnings




Quality of Service (QoS) warnings do not invalidate the result but are included as additional information:

    

  • IMAP LOGIN: 191 out of 1,506 transactions (12.68%) failed the 5 second response time requirement.
    • 

  • IMAP UID_COPY_RANGE_FOLDER: 280 out of 4,390 transactions (6.38%) failed the 5 second response time requirement.
    • 

  • IMAP UID_COPY_SERIES_FOLDER: 79 out of 644 transactions (12.27%) failed the 5 second response time requirement.
    • 

  • IMAP UID_FETCH_RANGE_UID_BODYPEEK_RFC822SIZE: 54 out of 333 transactions (16.22%) failed the 5 second response time requirement.
    • 

  • Remote Delivery Failure: 15,991 out of 17,400 messages (91.90%) were received by the remote mail sink during the 100% load run. The remote mail sink must receive at least 95% of the remote mail sent during the 100% load run.
