How much time are we talking about here? I suppose by 'time' we mean
loading time (load binary and signatures) + processing time (comparing
signatures).

Now, for loading time, when I start firefox within 5-6 seconds it
immediately fills up 250+ Mb memory so for 950+ Mb (clamd) loading time
shouldn't be that of an issue.

Please note that processing time will be the same doesn't matter whether
you keep clamd and signatures loaded *all the time* or load on demand.

Yes. The difference is hogging memory *all the time* and loading *on
demand*

Of course, at scanning time those signs/dbs need to be in memory. At
scanning time not *all the time*. e.g. I am expecting an email at 6 PM.
I don't mind clamd taking that much of a memory *at* 6 PM and then
release it. I find it absolutely inconvenient to having to forgo ~1GB
memory since the morning. As I said, a poor bargain.
