So you have 195,000 times the reading of 5,000 records. One thing that
would cause the nine-fold increase in time might be a reduction in buffer
size. Another thing that might affect performance tremendously (much more
than buffer size) is file caching. Does the new system cache files as much
as the old one? We don't know the actual byte size of the records of either
file, so it's a lot of guesswork, but a record of 100 bytes would make the
employee file 500,000 bytes, which might or might not remain in the file
cache, depending on some system configuration parameter.
