For instance, the token filter is significantly faster than the Snowball implementation of the Porter stemmer.Hunspell stemmers have to load all words, prefixes, and suffixes into memory, which can consume a few megabytes of RAM.Algorithmic stemmers, on the other hand, consist of a small amount of code and consume very little memory. While more-formal words tend to follow a regular pattern, the most commonly used words often have irregular rules.
If your collection is large, you likely will get good matches with lighter stemming. If it works well enough, there is no need to change it.Algorithmic stemmers are typically four or five times faster than Hunspell stemmers.“Handcrafted” algorithmic stemmers are usually, but not always, faster than their Snowball equivalents.Although the Lovins stemmer is the oldest stemmer by far , I'd say that Martin Porter's Porter Stemming  algorithm is by far the most popular one (i.e., the mostly used one).Note that Martin Porter updated the original Porter stemmer (see for more info).
