Word composition
The word is made up of 'Best-' (superlative of 'gut' (good)) and 'Leistung' (performance). So it literally means the 'beste Leistung' (best performance) that someone has achieved.
EXAMPLE
Mit diesem Sprung erreichte er seine persönliche Bestleistung.
With this jump, he achieved his personal best.
Typical verbs
'Bestleistung' (best performance) is often combined with certain verbs that describe achieving or improving something. Typical verbs are: eine Bestleistung 'aufstellen' (to set), 'erzielen' (to achieve), or 'verbessern' (to improve).
EXAMPLE
Der Athlet konnte seine bisherige Bestleistung um zwei Sekunden verbessern.
The athlete was able to improve his previous best performance by two seconds.
Typical collocation

Bestleistung vs Rekord
record
'der Rekord' and 'die Bestleistung' both have to do with the best result. 'Rekord' often means the best value overall in a particular area, for example in a competition or a sport. 'Bestleistung' refers more strongly to a specific person or group: it is the best result that this person or group has achieved. That is why a personal best performance can be very good without being a general record. The words can be confused especially in sports. Remember: 'Rekord' is often bigger and more public, while 'Bestleistung' is often more personal.
Bestleistung
Beim Training erreichte Max heute eine neue persönliche Bestleistung.
