Techniques for logging performance data are described herein. According to one embodiment, in response to a request for logging performance data, where the request includes a data type indicating a type of performance data and an actual performance data value, a non-linear mathematical operation is performed on the performance data value to generate an index value. The performance data represents a performance measurement of a predetermined operation performed by a data processing system. Thereafter, a value of a data field in a performance data store that stores the performance data is updated based on the type of the performance data and the index value. The value of the data field is updated without having to lock the data field for purpose of simultaneously accesses.

Performance logging framework

An email server receives an email sent to an email account and including one or more attachments. The one or more attachments are extracted from the email into one or more temporary storage elements. Content from the temporary storage elements is indexed. The indexed content is stored along with an identifier of the email in an index corresponding to the email account. The one or more temporary storage elements is disposed of after the indexing.

Server-side search of email attachments

The invention provides a cryptographic method which includes receiving at a first entity a second public key M. At least one of a first session key Kand a first secret Smay be generated based on the second public key M. A first random nonce Nmay be generated which may be encrypted with at least one of the first session key Kand the first secret Sto obtain an encrypted random nonce. The encrypted random nonce may be transmitted from the first entity. In response to transmitting the encrypted random nonce, the first computer may receive a data signal containing a modification of the first random nonce N. If the modification of the first random nonce Nwas correctly performed, then at least one of (i) opening a communication link at the first computer, and (ii) generating a first initialization vector Iis performed.
