Nonetheless it is possible to empirically adjust parameters to improve performance.
To the point of crashing. Some guidance is needed. Initial Windows client 1.3.87 crash tests with default settings are acceptable. The same cannot be said for Linux. I need to set up Tripwire to verify the round-trip data. See: ftp://creedon.biz/pub/afs_stress_tests/run1 (and 0) for details on crashing Linux. The test script is included. Close but no cigar. tedc -----Original Message----- From: Jeffrey Altman [mailto:[EMAIL PROTECTED] Sent: Saturday, August 13, 2005 5:16 PM To: ted creedon Cc: [email protected] Subject: Re: [OpenAFS] OpenAFS speed over the net With or without encryption? Increasing the number of threads will not necessarily increase performance. It may very well slow it down. There is a careful balance that must be kept between the SMB/CIFS and RX thread pools.
