For SQL Servers that happen to be depending on SAN (Storage Place Community) or NAS (Network Hooked up Storage) storage programs which are community dependent, every single network latency or network slowness may possibly/will lead to too much PAGEIOLATCH_SH (but in addition the other PAGEIOLATCH_XX waits) wait around type values due to incapability in the SQL Server to retrieve data from Actual physical storage to a buffer pool rapid adequate In case the PAGEIOLATCH_SH hold out type values are continuously greater than ten-fifteen seconds, this could be a trusted indicator of pressure on I/O subsystem and three previously mentioned outlined leads to must be carefully investigated Overloaded I/O subsystem by An additional processes which might be making the high I/O action
