To preface this, this all started when our z/OS tcp/ip person tested z/OS to z/OS hipersocket performance and found it nearly the same as using GBE osa connection. I immediately went 'huh' and went on to get hipersockets configured in the z/VM Linux guests.
I then ran some testing after doing so, to get some sort of benchmarks. Since I had trouble believing the numbers this person was getting (2.70 MB/sec for hipersocket xfer from z/OS LPAR to z/OS LPAR) I did my own testing and got the following: I'm surprised by the Linux to z/OS and z/OS to z/OS performance. If I am going to use this to whip db2 data about at warp speed, i have GOT to fix something. Any ideas/interpretations of this are welcome. results of sending file from z/VM Linux guest pepin to Linux LPAR nokomis using GBE OSA (z/900 to z/800) 100% |*************************************| 593 MB 13.45 MB/s 00:00 ETA 226 File receive OK. 621993984 bytes sent in 00:44 (13.45 MB/s) results of sending the file from z/VM Linux guest pepin to z/VM Linux guest calhoun using the hipersocket interface address of calhoun 100% |*************************************| 593 MB 39.02 MB/s 00:00 ETA 226 File receive OK. 621993984 bytes sent in 00:15 (39.02 MB/s) results of sending the file from z/VM Linux guest pepin to z/VM Linux guest calhoun using the OSA IP address of calhoun 100% |*************************************| 593 MB 16.18 MB/s 00:00 ETA 226 File receive OK. 621993984 bytes sent in 00:36 (16.18 MB/s) results of sending the file from z/VM Linux guest pepin to z/OS LPAR owl0 using the OSA IP address for owl0 125 Storing data set /it/public/Su810_001.iso 100% |*************************************| 595 MB 2.68 MB/s --:-- ETA 250 Transfer completed successfully. 624885855 bytes sent in 03:41 (2.68 MB/s) results of sending the file from z/VM Linux guest pepin to z/OS LPAR Owl0 using the hipersocket interface address for Owl0 125 Storing data set /it/public/Su810_001.iso 100% |*************************************| 595 MB 2.86 MB/s --:-- ETA 250 Transfer completed successfully. 624885855 bytes sent in 03:28 (2.86 MB/s) Just to compare, I allocated a flat file of sufficient size and tried the send again, after allowing for MVS dataset naming conventions. This was to factor out the performance factor of the HFS file system vs native.
