The Tchernobler minhag (al-pi Eliyahu Hanovi) is to complete the entire Sefer T’hillim, ‘bli-hefsek’ and before davening on Shabbos morning. This is 1 of the 3 most important minhagim of Skver and Rachmistrifka Chassidus.
I have done so more than a thousand times (every Shabbos for more than 20 years). With proper concentration, one can get quite proficient and complete it in less than 1 1/2 hours (I usually do it in 70-80 minutes – every word).
I look forward to Shabbos morning probably more than anything else.
