php - Improving query run time (Takes more than 20seconds to load a page) -

-

i've got query loaded everytime user open profile page. , slow. takes more 20 seconds load page. kinda simple query, alot of lines don't scared looking @ it. :)

i appericiate on improving query.

select      `h`.`login` `login`,     sum(if(((`h`.`cmd` = 0) or (`h`.`cmd` = 1)),`h`.`pips`,null)) `total_pips`,     count(if(((`h`.`cmd` = 0) or (`h`.`cmd` = 1)),`h`.`position_num`,null)) `total_trades`,     (count(if(((`h`.`pl` > 0) , ((`h`.`cmd` = 0) or (`h`.`cmd` = 1))),`h`.`pl`,null)) / count(if(((`h`.`cmd` = 0) or (`h`.`cmd` = 1)),`h`.`position_num`,null))) `winning_trades_percent`,     sum(if(((`h`.`cmd` = 0) or (`h`.`cmd` = 1)),`h`.`gain`,null)) `total_gain`,     (select avg(`wg`.`weekly_gain_all`) `gt_view_weekly_gain` `wg` (`wg`.`login` = `h`.`login`) group `wg`.`login`) `weekly_gain`,     avg(if(((`h`.`pips` > 0) , ((`h`.`cmd` = 0) or (`h`.`cmd` = 1))),`h`.`pips`,null)) `average_profit_pips`,     avg(if(((`h`.`pips` <= 0) , ((`h`.`cmd` = 0) or (`h`.`cmd` = 1))),`h`.`pips`,null)) `average_lose_pips`,     avg(if(((`h`.`cmd` = 0) or (`h`.`cmd` = 1)),`h`.`pips`,null)) `average_pips`,     avg(time_to_sec(if(((`h`.`cmd` = 0) or (`h`.`cmd` = 1)),timediff(`h`.`close_time`,`h`.`open_time`),null))) `average_trade_time`,     std(if(((`h`.`cmd` = 0) or (`h`.`cmd` = 1)),`h`.`pips`,null)) `volatility`,     max(if(((`h`.`cmd` = 0) or (`h`.`cmd` = 1)),`h`.`pips`,null)) `best_trade`,     min(if(((`h`.`cmd` = 0) or (`h`.`cmd` = 1)),`h`.`pips`,null)) `worst_trade`,     (ceiling(((ceiling(to_days(now())) - ceiling(to_days(min(if(((`h`.`cmd` = 0) or (`h`.`cmd` = 1)),`h`.`open_time`,null))))) / 7)) - 1) `running_weeks`,     (select `fn`.`followers_num_all` `gt_view_followers_num` `fn` ((`fn`.`guru_id` = `h`.`guru_or_guru_user_id`) , (`h`.`is_guru_history` = 1))) `followers_num`,     sum(if(((`h`.`cmd` = 0) or (`h`.`cmd` = 1)),`h`.`pl`,null)) `total_profit_loss`,     sum(if(((`h`.`cmd` = 6) , (`h`.`pl` > 0)),`h`.`pl`,null)) `deposits`,     sum(if(((`h`.`cmd` = 6) , (`h`.`pl` < 0)),`h`.`pl`,null)) `withdrawls`,     count(if((((`h`.`cmd` = 0) or (`h`.`cmd` = 1)) , (`h`.`pl` > 0)),`h`.`position_num`,null)) `total_winning_trades_count`,     abs((avg(if(((`h`.`pips` > 0) , ((`h`.`cmd` = 0) or (`h`.`cmd` = 1))),`h`.`pips`,null)) / avg(if(((`h`.`pips` <= 0) , ((`h`.`cmd` = 0) or (`h`.`cmd` = 1))),`h`.`pips`,null)))) `average_profit_loss_ratio`       `gt_history` `h`      `h`.`is_closed` = 1 group     `h`.`login`

it seems query computes values users. if wish display 1 user, might faster add and (login='xxx') in clause.

otherwise, mihai suggested, caching might best approach.

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
