32 cpconfig cpconfig Check Point products are configured using the cpconfig utility. When run, this utility displays a screen with the configuration options. The options that are displayed, depend on the installed configuration and product(s). You can use cpconfig to enable or disable Performance Pack. Once you have selected an acceleration setting, the setting remains configured, until you choose to change it on another occasion. In other words, the settings that you define will remain even after the machine is rebooted. For an alternative method to enable or disable acceleration, see fwaccel on page 28. Usage Execute cpconfig by entering the following command: cpconfig An interactive menu will be displayed providing you with the option to enable or disable the acceleration by selecting Enable/Disable Check Point SecureXL. Select Enable in order to enable acceleration. Select Disable in order to disable acceleration. sim affinity The sim affinity utility controls various Performance Pack driver features and applies only for SecurePlatform. Usage sim affinity [-a -s -l] Parameters Affinity is a general term for binding Network Interface Card (NIC) interrupts to processors. By default, SecurePlatform does not set Affinity to the NIC interrupts, which means that each NIC is handled by all processors. Optimal network performance is obtained when each NIC is individually bound to a single processor. To achieve the above, the sim utility includes an Affinity feature, which has the following operation modes: 32

33 sim affinity Table 3-3 sim Affinity operation modes Option Explanation -a Automatic Mode the Affinity is determined automatically, by analyzing the load on each NIC. If the NICs are not loaded, the Affinity will not be set. This is the default Affinity operation mode, in which the Affinity is re-tuned every 60 seconds. -s Manual Mode allows you to manually specify the Affinity settings. For each interface, you will be asked to enter one of the following: A space-separated list of the processor numbers that are to handle this interface, or The word all, to allow all processors to handle this interface. When setting the Affinity manually, the periodic automatic check will be disabled. After booting, it will remain disabled and the Affinity settings entered manually will be applied. -l View a list of the current Affinity settings. Chapter 3 Command Line 33

34 proc entries proc entries Performance Pack supports SecurePlatform proc entries. These entries are used to display information about the Performance Pack. The proc entries are read-only entries. They cannot be configured. The proc entries are located under /proc/ppk. Usage cat /proc/ppk/[conf ifs statistics drop statistics] Parameters Table 3-4 /proc Parameters Parameter conf ifs statistics drop statistics Explanation Displays the Performance Pack Configuration. Lists the interfaces to which Performance Pack is attached. Displays general Performance Pack statistics. Displays Performance Pack dropped packet statistics. 34

36 Performance Tuning Performance Tuning In This Section Amount of Concurrent Connections and Hash Size page 36 SecureXL Templates page 37 Delayed Notification page 37 Connection Templates page 37 Delayed Synchronization page 39 Multi-Core Systems page 39 Amount of Concurrent Connections and Hash Size Setting the Maximal Concurrent Connections To set the desired number of maximal concurrent connections, open SmartDashboard s Gateway Object Properties window and proceed as follows: 1. Open the Capacity Optimization tab. Make sure that Calculate connections hash table size and memory pool is set to Automatically. 2. Set the desired amount of concurrent connections in the Maximum Concurrent Connections field. Increasing the Number of Concurrent Connections You can increase the actual number of concurrent connections by reducing the timeout of TCP and UDP sessions: TCP end timeout determines the amount of time a TCP connection will stay in the FireWall connection table after a TCP session has ended. UDP virtual session timeout determines the amount of time a UDP connection will stay in the FireWall connection table after the last UDP packet was seen by the gateway. By reducing the above values, the capacity of actual TCP and UDP connections is increased. 36

37 SecureXL Templates SecureXL Templates Verify that templates are not disabled using the fwaccel stat command. For further information regarding SecureXL Templates, see sk32578 at Delayed Notification In the ClusterXL configuration, the Delayed Notification feature is disabled by default. Enabling this feature improves performance (at the cost of connections' redundancy, which can be tuned using delayed notifications expiration timeout). The fwaccel stats command indicates the number of delayed connections. The fwaccel templates command indicates the delayed time for each template under the DLY entry. Connection Templates General Connection templates are generated from active connections according to the policy rules. The connection template feature accelerates the speed at which a connection is established by matching a new connection to a set of attributes. When a new connection matches the template, connections are established without performing a rule match and therefore are accelerated. Connection templates are generated from active connections according to policy rules. Currently, connection template acceleration is performed only on connections with the same destination port. Examples: A connection from /2000 to /80 established through Firewall and then accelerated. A connection from /2001 to /80 fully accelerated (including connection establishment). A connection from /8000 to /80 fully accelerated (including connection establishment). HTTP GET requests to specific server will be accelerated since the connection has the same source IP address. Chapter 4 Performance Tuning and Measurement 37

38 Connection Templates Restrictions In general, Connections Templates will be created only for plain UDP or TCP connections. The following restrictions apply for Connection Template generation: Global restrictions: SYN Defender Connection Templates for TCP connections will not be created. NAT connections. VPN connections. Complex connections (H323, FTP, SQL). NetQuotas. ISN Spoofing. If the Rule Base contains a rule regarding one of the following component, the Connection Templates will be disabled for connections matching this rule, and for all of the following rules: Security Server connections. Services with source port range. Time objects in the rules. Dynamic Objects and/or Domain Objects. Services of type other with a match expression. User/Client/Session Authentication actions. Services of type RPC/DCERPC/DCOM. When installing a policy containing restricted rules, you will receive console messages indicating that Connection Templates will not be created due to the rules that have been defined. The warnings should be used as a recommendation that will assist you to fine-tune your policy in order to optimize performance. Testing To verify that connection templates are enabled, use the fwaccel stat command. To verify that connection templates are generated, use fwaccel templates. This should be done while traffic is running, in order to obtain a list of currently defined templates. 38

39 Delayed Synchronization Delayed Synchronization The synchronization mechanism guarantees High Availability. In a cluster configuration, if one cluster member fails, the other recognizes the connection failure and takes over, so the user does not experience any connectivity issue. However, there is an overhead per synchronized operation, which can occasionally cause a system slow-down when there are short sessions. Delayed synchronization is a mechanism based upon the duration of the connection, with the duration itself used to determine whether or not to perform synchronization. A time range can be defined per service. The time range indicates that connections terminated before a specified expiration time will not be synchronized. As a result, synchronized traffic is reduced and overall performance increases. Delayed Synchronization is performed only for connections matching a connection template. Note - Delayed synchronization is disabled if the log or account are enabled. Currently, delayed synchronization is allowed only for services of type HTTP or None. In order to configure delayed synchronization, proceed as follows: 1. In SmartDashboard, right click on the Service tab. 2. Either edit an existing service or click New and select TCP. The TCP service properties window is shown. 3. After defining TCP parameters, click Advanced in the TCP service properties window. The Advanced TCP Service Properties window is shown. 4. Select the HTTP or None protocol from the Protocol Type list. 5. Check Start synchronizing. 6. Define the duration value Seconds after connection initiation. The duration value is specified in seconds. Multi-Core Systems Running Performance Pack on multi-core systems may require more advanced configurations to account for core affinity and IRQ behavior. For more information, see sk33250 at Chapter 4 Performance Tuning and Measurement 39

40 Performance Measurement Performance Measurement TCP State and Benchmarking Certain testing applications (SmartBits or Chariot) generate invalid TCP sequences. The Security Gateway s TCP state check detects these faulty sequences, and drops the packets. As a result, the benchmark fails. Since these TCP sequences are invalid, they may affect overall Firewall performance. To disable this type of TCP state check, perform the following operations in SmartDashboard: 1. In the IPS tab, select Protections > By Protocol > Network Security > TCP > Sequence Verifier. 2. Select the profile assigned to your gateway and click Edit. 3. In the Action field, select Inactive. 4. Click OK to close the Protections Settings window. 5. Click OK to close the Protections Details window. 6. Click Install Policy to apply the changes. Non-accelerated traffic analysis Use the fwaccel stats command to verify the amount of non-accelerated traffic compared to accelerated traffic. Use the sim dbg + f2f command to understand the possible reasons for the non-accelerated traffic. Performance Troubleshooting Additional CLI commands, such as ethtool, are available to monitor the performance of the gateway. For a list of these commands and explanation of their usage, see sk33781 at 40
