Installing OS lion upgrade

Hi, My Mac is slow enough and I am afraid that the 10.7.5 update may make it even slower. Appreciate an advice in this regard.

MacBook Pro, Mac OS X (10.7.5)

Then, you're running OS X 10.7.4. if you failed to retain a bootable backup/clone of your previous Snow Leopard (10.6) installation, then you're probably stuck with Lion, unless you reinstall SL onto an empty volume, boot with it, and reinstall the apps and reset your user and network settings. See Kappy's going back to SL from Lion guide or ds store's How to revert your Mac to Snow Leopardguide for more details. Otherwise, fix the 10.7.4 volume following the steps in the articles I mentioned above.
