Why is gmail search slower than google search.
What determines search speed and differences in the functionality and features.
Search query -> indexed information -> locates set of documents -> returns URL and snippets -> displays the same
lets us examine the indexed info and set of documents aspects.
What adds latency is essentially when the record needs to be located, and the time it takes to locate.
And that is based on volume of information and how it is stored and how it is queried.
When I search for a search query on web search, the volume of indexes is essentially the entire world information. So the data volume is HUGE.
When i search for email , the volume of indexes is very small as we already know we are searching within an individual index. For this specific email account.
However there are millions of email accounts, and there is always the step of having to find your email account. Google likely does not have a static IP location or server dedicated to just your account, so it does have to go through accounts of millions of people and find your account, and then find your email.
The result has to be always pulled mostly from a server unless you are searching the same thing again.
Your search cannot apply to someone else , so caching will be highly limited cache hit ratio would be low for gmail, and very high for google.com queries.
