I'm working with a production database connecting remotely. All the datafiles, index files and log is placed on the same disk but in different filegroup names based on separate physical files. But I expect if I place the index files or/add log files separate from the datafiles I mean in different disk it will improve the performance.
If my expectation is correct then can I change the place of the index and log files in separate location while the database is on-line yes the database is implemented with log-shipping too.
Please evaluate my query and do give a proper suggestion.
Thanks in advance
Sunilsurely it will improve the performance if the log files are placed seperate
from the data files (different disks).
for the indexes u can delete the existing index and recreate it specifying
the new location.

Creating new files doesn't automatically improve
performace, it also depends upon the raid configuration of
the disk its going on.
For instance putting a log file on a RAID 0 disk will make
it faster than putting it on a raid 5 disk.
Although its different for every type of application a
normal implementation with cost constraints its to put the
log files on a raid 0 or raid 0+1 with the data files on
raid 5.
