Phoenix Performance and Anti-virus software

How anti-virus scanners could impact software performance 1) Launching executables Some anti-virus software can be configured to do threat assessment on executables prior to the operating system executing. How a particular virus scanner does this could affect performance. It may have a hook into the Operating System to prevent execution of an executable until it identifies it as a threat. This hook could incur a performance penalty. How it identifies could incur an additional penalty on performance. 2) Scanning files on read/write/close Some anti-virus software can be configured to scan any file on read, write and/or close. It could inject itself into the file open/close process, as well as the stream read/write. All of this would likely incur a performance penalty, especially if it is scanning a lot of data. 3) Socket communication Some anti-virus software can be configured to do threat assessment on socket connect and streaming of data. This could also incur performance hits on applications using TCP/IP communications. Items 1) and 2) can affect Phoenix overall performance. The more intensive calculating engines leverage the file system and external executables to process the data. Item 3) can impact performance with PKS If performance on a system is suspect, someone familiar with the anti-virus software should check to see if it can be configured to turn of certain anti-virus features as they relate to Phoenix.
