摘要： Systems and media for detecting outbound Nagling on a TCP network connection are disclosed. Embodiments may include creating by a sender computer one or more segments to be transmitted to a receiver computer and determining by the sender computer whether any of the one or more segments to be transmitted are small segments and determining whether a previously transmitted small segment is unacknowledged by the receiver computer. If the previously transmitted small segment is unacknowledged by the receiver computer and at least one of the segments to be transmitted is a small segment, embodiments may also include detecting by the sender computer a Nagling condition on the network connection. Further embodiments may include modifying a Nagle algorithm configuration of the network connection in response to the detected Nagling condition by turning off the Nagle algorithm or reducing a delayed acknowledgement timer for the network connection.

摘要： Systems for detecting Nagling on a TCP network connection are disclosed. Embodiments may generally include a system with a Nagle detection threshold determiner for determining a Nagle detection threshold based on the network connection. The system may also generally include a Nagle detection module in communication with the Nagle detection threshold determiner for observing a small segment at a second time following an acknowledgement indicative of a Nagling condition at a first time, wherein the Nagle detection module also may detect a Nagling condition if the difference between the second time and the first time is less than or equal to the Nagle detection threshold. The system may be a receiver computer or a network computer. The system may also generate and transmit a notification of the Nagling condition, increment a Nagle monitor counter, or save an indication of the Nagling condition in a log.

摘要： Some embodiments provide a method for identifying an event for a particular category. The method classifies several documents as relevant to several different categories. The method identifies a number of documents relevant to the particular category for a current time period and a background time period. Based on a comparison of the number of documents from the current time period relevant to the particular category and the number of documents from the background time period relevant to the particular category, the method identifies an event for the category for the current time period. Some embodiments calculated a score for the event, and normalize the score based on an average number of documents relevant to each of a set of related categories including the particular category.

摘要： A data processing system performs a multithreaded performance benchmark with a rampup interval and a rampdown interval. The master thread signals a start test event and begins the rampup interval. After the rampup interval, the master thread signals a start measurement event. In response to the start measurement event, the worker threads record the units of work they complete. After the measurement interval, the master signals the workers to stop measuring, but to continue running. This begins the rampdown interval. After the rampdown interval, the master thread signals a stop test event. The rampup and rampdown intervals are long enough to ensure that measurements are not recorded during skew intervals. Thus, thread skew does not impact the results.
