Probably in this case it takes reasonable amount of time...

Well, your questions forced me to do my own investigation of gzip
performance in one real-life scenario which I hope to use really soon. I
took my Neo FreeRunner and tested gzip decompression speed there. Time
to read 10Mb file is about ~ 2.15s. But if I need to read and decompress
it at the same time it takes ~ 9.90s. So this makes times slower read of
compressed files. Since stardict reads all index files on each startup
and currently index files of my dictionaries occupy more than 20M this
makes much longer startup time. I have not checked runtime performance.
It'll be affected too but, probably, not too much since stardict will
decompress only required parts of data. But anyway gzip is not free and
it's better to have it optional.
