Problem Note 58811: When using SAS/ACCESS® Interface to the PI System to read snapshots for many tags, you might experience slow performance
 |  |  |  |  |
When you use the TAGLIST option to read snapshots for many tags, SAS/ACCESS Interface to the PI System might perform quite slowly. Even when bulk reading is used, performance in reading the tags is poor.
The problem occurs because each tag is handled individually, causing numerous network round-trips and long network lags as SAS processes the hundreds of tags.
