Asked a question about my poor DFSKERN SMB performance; few takers. So let me pose it another way.
Who is running z/OS using SMB and it is running just fine as far as CPU usage. 1. Are you using HFS or zFS files. 2. Would the SMB share being accessed by Windows Servers or UNIX/LINUX 3. Are any of you zFS or HFS files large with a bunch of small files. 4. Are you running in a Parallel Sysplex on just have one system. My hunch is still it is a zFS issue although this is being worked by the SMB people in IBM. I am not sure how well they talk. Attending SHARE in Orlando early in the year, I sat in almost a full day of USS sessions where each IBM speaker spent a portion of the session (it was not written on the handouts) apologizing for the poor performance of large zFS systems with many small files. They said they understood the issue and were working to improve it. Reviewing the SHARE presentations for both Orlando and San Jose on the SHARE web site, to learn if there was any progress. Then a couple of additional questions: 5. If anyone attend the San Jose SHARE, did they mention the issue and also any progress. 6. In general has anyone been involved with IBM to look at the performance issues of large zFS files with many, many, many small files. jim ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
